More than 80 per cent of concrete produced in developed nations is used as ready- mix. In India, however, it is less than nine per cent. What is stopping the RMC market from taking off? ICR interacts with Bankat Mandhania, Director, Ashtech (India), a leading cement and ready- mix concrete manufacturer in the country, to get some insights. Excerpts from the interview.

How is the RMC market performing?

If you talk about growth, yes it is there as more people are realising the advantages of using RMC. Once someone uses RMC, he is bound to be convinced of the advantages. After this, he will be ready to shell out extra for the product since what is gained in return is good service along with a good product. As per sustainability, the business goes on as there is no entry barrier to the RMC sector. Anybody can set up a RMC unit. So it is open to competition. We do not get premium for a brand name. Leading cement companies are out there in the RMC business, but if you see the revenues, they are not making too much money there. But they are there for sure.

Why is the demand for RMC so little in India compared to foreign countries?

Though the demand is less in India, the RMC market is growing. Yes, it is true that in foreign countries today, 90 per cent of the concrete manufactured is sold in RMC form. Here things are a bit different. If you check Indian markets, almost 70 per cent of the cement is sold in bags. That gives you a comparison between the two. Masons and builders here need to be updated and that takes time. But once the builder uses RMC, he understands the advantage. It also requires some volume of work to be done over a period of time. But those into constructing small buildings and two floor apartments are will not go for RMC. Once we start doing sizeable projects, the construction community will experience the benefits of RMC first- hand.

Is the equipment readily available for RMC production?

You have the entire spectrum of manufacturers in India. You have players from Ahmedabad-based companies catering to local markets and foreign multinationals. There is a vast spectrum of RMC equipment to choose from. All the standard equipment is from standard manufacturers worldwide so you are not compromising on quality of equipment for sure. Availability is not a problem, the choice is there, and any type or size is there.

It is said that crushed sand is not as good as natural sand. What is your take on this?

The natural sand that we are talking about is no longer available. There is no river sand anymore in the area of Mumbai. We are using creek sand which is by itself, never recommended. It is as an alkaline material. River sand was used in the British era, ferried from Gujarat. So Marine Drive and everything that is British- built, was all done with river sand. They got it 60 years back to ensure quality construction; there is no river sand as such in India today. Also, in the name of manufactured sand, we are using powder and that is stone dust. For manufactured sand you need a VSI plant, which has come into Mumbai just a few years ago. Pune is more mature in terms of sand use. They are using crushed sand for plasters too. Now crushed sand manufactures here too, have fantastic gradations available with them.

Are we stuck with the minimum grades of concrete?

The grade of concrete depends on the end application. The more challenging the structural demand, the higher the grade of concrete used is. It is wrong to say we cannot do it. M70 is what we used for the JJ flyover about seven years ago. The Bandra-Worli Sea link is made with M60 grade concrete. All Metros have got M60 specified material. So we are able to manufacture a wide range of concrete. The biggest market here is the residential market where buildings are from four floors to 40 floors. M30 grade concrete will satisfy the structural demands of a four- floor building. The higher the building, the higher the grade requirement is. World One (the world´s tallest residential tower by the Lodha Group) is using M90; they are producing it and they are doing a good job. We have variations in grade available to suit our requirements and we also have a good knowledge base.

Is skilled workforce available adequately?

We are definitely falling short of good quality manpower. There is a shortage of quality control people, too. We are nowhere near the international standards of an available workforce in terms of quality and in sufficient quantity. In India, people have little option but to compromise on a lot of things. Although the country sees large numbers of engineers graduating every year, very few of them are employable. Whether we can handle this type of concrete demand is a question mark. You have enough civil engineers but are they really employable?

How do you deal with it? Do you have a separate training module for them?

We take two to three civil engineers every year and we mould them. You have to nurture them. Employability or job requirement is something you have to pay attention to and you have to take that effort and make sure that they understand and learn the industry´s requirements. Then, a couple of years down the line, you can give them additional responsibilities. We take fresh engineers every year. When we see candidates with good potential, we create opportunities for them and ensure that they stay with us. Skill shortage is an issue in RMC.

What are the other challenges encountered in the RMC sector?

Logistics is the biggest cost component in the whole chain. The transit mixer costs almost Rs 30 lakh and it can deliver only that much quantity in a day. The stronger the asset base, the better the company, and it can be relied upon by the consumer as a supplier. It works both ways. You have to ensure that the deliveries are made on time and that the material is poured as per schedule irrespective of hassles such as traffic or roadblocks. The system must be robust enough to absorb and respond to any issue that can pop up on the fly.

So how do you manage this?

We have 74 transit mixers and 24 pumps. We follow a process of sending a questionnaire to our consumer that asks for all the details including the peak requirement for the material. Based on this, we design equipment required for the work. That determines if there are going to be two slabs every day for one site, so a minimum of two pumps and seven transit mixers are required, and that too, if the site is close. But if the same site is far away, I will need 12 transit mixers. So having a complete understanding of the customer`s requirement and a solid contingency plan in place is key in this business.

Efficient Oil Cooling for Gearbox in the Cement Industry. How a High-Performance Plate Heat Exchanger Ensured Thermal Stability and Operational Continuity.

Contributed by: Narendra Joshi and Sourabh Mishra

Application: Gearbox Oil Cooling
Objective: To maintain optimal oil temperature in high-viscosity lubrication systems for gearboxes in cement plants, ensuring uninterrupted operations and minimizing production losses due
to overheating.
Challenge: A prominent cement manufacturing company’s conventional cooling systems were failing to maintain the oil temperature within the optimal range, jeopardizing equipment performance and leading to avoidable downtime.

Background with the Existing System
In heavy-duty industrial applications, particularly in the cement industry, gearboxes are critical components that must operate under high mechanical loads and harsh conditions. These gearboxes rely on lubrication systems where oil plays a dual role, lubrication and heat dissipation. A recurring challenge in such setups is managing the temperature of the gearbox oil. When oil heats beyond a critical limit, its viscosity drops, reducing its ability to form a protective film. This leads to increased friction between components, heat generation, and eventual damage to gearbox components — directly impacting plant uptime and production output.

Delivering Sustainable Heat Transfer Solution with HRS FUNKE High Efficiency Heat Exchanger
This system was selected for its:

  • Excellent thermal performance, ensuring rapid and efficient oil cooling even with high-viscosity fluids.
  • Leakage-proof operation, with no cross-contamination between cooling water and lubrication oil.
  • Robust design, capable of withstanding high operating pressures and variable flow conditions.

The plate exchanger was custom configured based on the oil’s properties, desired outlet temperature, and ambient heat load, ensuring that the oil remained within the specified viscosity range necessary for maintaining gearbox operation and lubrication integrity.

Performance Benefits Delivered

  • Oil temperature control and maintained consistently within target range
  • Viscosity stability and prevented breakdown of lubrication film
  • Equipment reliability and reduced risk of gearbox overheating or failure
  • Production continuity and eliminated unplanned stoppages
  • Long-Term savings and lower maintenance costs and extended oil life

Solution: To address the problem, HRS Process Systems Ltd recommended the installation of a Funke Plate Heat Exchanger a compact, high-efficiency thermal solution engineered specifically for industrial lubrication oil cooling.

Conclusion: The customer achieved precision oil temperature control, ensuring that the gearboxes operated at optimal conditions. This not only safeguarded the mechanical integrity of the gearbox but also directly contributed to higher plant uptime and improved production efficiency in heavy industries like cement manufacturing.

How Upgrades Can Deliver Energy Savings Across the Cement Process

Published

Jacob Brinch-Nielsen, Vice President of Professional Services, FLSmidth Cement, brings together recommendations from experts across the flow sheet to demonstrate the role of upgrades in optimising the cement manufacturing process.

Improving energy efficiency in material transport
Pneumatic conveying offers a cleaner and more contained alternative to mechanical conveying. However, pneumatic systems can also be energy-intensive, with inefficiencies arising from air leakage, pressure losses, and outdated equipment designs. Optimising these systems can significantly reduce energy consumption and operating costs.
“One major challenge is maintaining efficient air-to-material ratios, as excessive air use leads to unnecessary power consumption,” explains Emilio Vreca, Manager of PT Product Engineering “Leaks in piping and inefficient compressors further compound energy losses. To address these issues, upgrading to the latest pneumatic conveying solutions can yield substantial improvements.”
The latest pump design—the Fuller-Kinyon® (FK) ‘N’ Pump—provides power savings of up to 15 per cent thanks to an improved seal, while an extended barrel and screw design have improved volumetric efficiency by more than 15 per cent. Similarly, the latest generation Ful-Vane™ Air Compressor has been engineered for increased energy efficiency, with an improved inlet area for capturing larger air flows and compatibility with variable frequency drives.

Optimising energy efficiency in packing and dispatch
Even minor inefficiencies in bagging and palletising can lead to higher maintenance demands, increased material waste, and unnecessary energy use. Reducing these inefficiencies is yet another lever to improve overall plant performance and sustainability.
Upgrading rotary packers enhances weighing accuracy, reduces spout-to-spout variations, and lowers reject rates, improving both product consistency and energy efficiency. Similarly, replacing pneumatic drive systems in palletisers with electric alternatives eliminates compressed air dependency, leading to more precise bag handling and reduced energy demand. These targeted upgrades help streamline operations while minimising environmental impact.
A key development in dust control is the FILLPro™ Dust Reduction Kit for GIROMAT® EVO. “By refining material flow and fluidisation, FILLPro reduces dust emissions at the source, improving bagging efficiency and plant cleanliness,” explains Gabriele Rapizza, Proposal Engineer. “This reduces material loss, prevents blockages, and cuts down on maintenance, helping plants achieve a more stable and energy-efficient packing operation.”

How services contribute to increased energy efficiency
In the past, many viewed the role of the supplier as a “sell-and-move-on” model. Things have certainly changed. As cement producers face challenging markets, heightened competition, and increasingly ambitious decarbonisation targets there is little room to tolerate inefficiencies within the plant. The paradigm has shifted such that the value of expert services is as essential as the initial equipment supplied. Furthermore, as digital solutions progress at speed, a fluid, long-term partnership gives cement plants the best platform to take advantage of the latest tools.
Whether it’s an audit to identify why energy efficiency has decreased from one year to the next, or even an optimisation package preparing your plant for carbon capture solutions – we are believers in the principle that there is always more we can do to improve efficiency. For example, our Online Condition Monitoring Services (OCMS) provide continuous monitoring of critical equipment such as the kiln, mills, cooler and fans, aggregating data and utilising advanced algorithms to identify potential trouble spots. As the OEM and an experienced full solutions provider, we can support these services with expert advice, not only alerting you to a problem but also providing recommendations as to how to remedy it or attending site to support you in person.

Small upgrades, big impact
Energy efficiency is a critical factor, influencing both operational costs and sustainability goals. While large-scale innovations such as carbon capture will play an essential role in long-term decarbonisation (and steal the headlines), incremental mechanical upgrades offer an immediate pathway to lower energy consumption with minimal disruption.
By optimising key process areas — grinding, dosing, combustion, cooling, and material transport — you can achieve measurable energy savings while improving performance and flexibility. These solutions provide a strong return on investment and pave the way for a more sustainable cement industry.
