Precast concrete technology adds value and reduce cost of the project as compared to cast in-situ built.
In India, there is a huge demand for housing which neither the cities nor the housing sector is prepared for. The construction industry is also facing problems such as shortage of skilled labour, poor workmanship, low productivity and quality of construction plus time and cost overruns, to name a few. Using precast (pre-engineered pre-cast) concrete method improves the speed of construction and saves huge cost.
Concept of precast construction includes those buildings, where the majority of structural components are standardised and produced in bulk quantity which, later, together with other pieces, becomes part of a larger structure. These precast concrete elements are prepared, cast and hardened at specially-equipped plants with a permanent location in plants at project site or in a location away from the building site, and then transported to the site for assembly.
In order to get the best result from the precast concrete technology, experienced precast architects or structural engineers are required, along with well-trained and experienced erection crews are also must to carry out the site work with utmost satisfaction. Precast concrete products do not need any finishing (such as plastering) on site. By using coloured aggregates and form liners beautiful patterns can be achieved on facades/outer load bearing walls of building.
The precast concrete building technology can be efficiently and effectively used for townships, affordable and low-cost mass housing, IT/ITES parks and SEZs at a much competitive cost and on-time schedule to be adopted in the construction sector of India.
Advantages of precast concrete elements
- Production in controlled environment results in high quality of factory-made strong durable products
- Repetition of standard precast elements will lead to cost reduction
- Plastering on precast walls and floor slabs is not needed because of smooth finishing
- Production can continue in any weather condition
- Better health and safety standards as compared to the conventional construction methods
- Project can be better planned, managed and controlled. High speed can be achieved
- Fast construction, less manpower required on site, and no shuttering required on site
- Door and window frames can be installed in the wall panels before erection
- Electricity conduits, pipes and boxes can be embedded in precast panels
- Large span floor system leads to more flexibility as internal columns are avoided
- Thin precast walls and facade panels increase the carpet area and reduced self-weight, increased life load
- Precast concrete is a durable material, which requires less maintenance
- Precise reinforcing during prefabrication saves steel
- Precise consumption of all material used
- Precast plant at site can reduce transportation distance and increase speed of erection
Precast concrete technology adds value and reduce cost of the project as compared to cast in-situ built versus precast:
- Construction time cost = 50-60 per cent
- Labour numbers on site cost = 50-60 per cent
- Waste material on site cost = 40-45 per cent
- Cost due to less snagging = 40-50 per cent
Indiapreacast.com gives full support for complete range of precast plants and machinery for manufacturing all types of precast concrete elements, including that of affordable/mass housing (even for on-site plants) like:
- Load bearing hollow core planks
- Lightweight non-load bearing wall panels, boundary wall, etc.
- Can manufacture panels at project site
- Saves transportation and government taxes
Project investment for 100 x 600 mm: Less than Rs 1 crore at Indiaprecast plant. European plants: Rs 8-12 crore. Project requirement: Land required: 1.5 acre plus, having length to width ratio 5:1. Power: 50 Kw is required for only wall panel production. Water: 10,000 liters per day. Labour: Average skilled labours 12 to 15. Raw Material: Cement, sand, aggregate 6 to10 mm/LECA: 2 to 10mm. Speed of Extruder m/c. -1.6 m/min.
Plant capacity: 400 m2/12 hours shifts.
Plants for pallet circulating system (PCS)/carousel system
In hi-tech and high-capacity computer controlled pallet circulating system/carousel system, the production of solid and sandwich elements is highly flexible. The system has been optimised for production of elements up to 12m in length and 4m in height. The employees specialise on individual working steps and are therefore more reliable and competent at their supervising workstations.
Production pallets are transported between the workstations using two side shifters, two concrete spreaders supplying concrete in either grey or coloured form, two vibrating units ensure that the concrete is compacted correctly and power trowels are used to guarantee smooth surfaces, insulated curing racks with 30 places provide the ideal conditions for element curing. A plotter, cleaning and oiling equipment and tilting station all serve to boost the efficiency of the system.
Concept of a carousel system
- Concrete elements are produced on work tables (pallets)
- Pallets are transported to the working stations, shuttering, reinforcement, concreting and compaction
- After the curing time of eight hours at the curing places the finished elements will be removed and the empty pallet will be transported to the next working station
- There are various methods for making affordable/mass/EWS/LIG housing by precast technology. Some of the most comm-only used are:

ABB reconditions 25 drives at ACC’s Jamul cement plant, avoiding 16 tonnes of CO₂ emissions while improving reliability through predictive maintenance.
Chhattisgarh
ABB has signed a multi-year Motion OneCare service agreement with ACC Limited, part of the Adani Group, to modernise ageing industrial drives at its Jamul cement plant in Chhattisgarh, improving operational reliability while avoiding approximately 16 tonnes of carbon dioxide (CO₂) emissions without disrupting production.
Announced on 27 October 2026, the agreement combines scheduled drive reconditioning, digital condition monitoring and energy appraisals to extend equipment lifespan, improve plant uptime and optimise maintenance costs. The initiative marks a shift from conventional equipment replacement towards a more resource-efficient approach to industrial asset management.
The first phase, completed in April 2026, involved the on-site reconditioning of 25 ABB ACS800 variable speed drives without a major plant shutdown. By retaining the existing cabinets and restoring the drive modules rather than replacing entire panels, ABB helped ACC preserve capital investment, minimise material consumption and avoid approximately 16 tonnes of CO₂ emissions.
A second phase, covering an additional 25 ACS800 drive modules, is scheduled for the fourth quarter of 2026. The programme is designed to improve long-term equipment reliability while allowing maintenance activities to be aligned with the plant’s operational schedules.
The ACS800 drives, installed at Jamul in 2010, had delivered more than a decade of near-continuous service in demanding cement manufacturing conditions. However, ageing electrical components and changing fault patterns had begun to affect their ability to meet the plant’s reliability requirements.
Rather than opting for complete equipment replacement, ACC engaged ABB’s certified engineers to conduct a comprehensive asset health assessment. The evaluation found that the existing cabinets and enclosures remained structurally sound, making targeted reconditioning a technically viable and cost-effective alternative to full replacement.
Drawing on nearly two decades of experience with ACC’s equipment and operating requirements, ABB developed a maintenance framework tailored to the plant’s shutdown windows, budget cycles and production priorities.
The Motion OneCare agreement incorporates planned equipment restoration, condition-based monitoring and energy assessments, enabling ACC to adopt a more systematic approach to maintaining critical electrical infrastructure.
As part of the programme, ACC has implemented ABB Ability™ Digital Powertrain Insights to monitor drive performance and identify emerging operational issues before they result in equipment failures.
The digital platform provides continuous visibility into parameters such as temperature, current, vibration and fault patterns. These insights allow maintenance teams to detect early signs of equipment deterioration, schedule interventions more effectively and reduce the likelihood of unexpected downtime.
Amit Gupta, Local Division Manager, Motion Services, ABB India, said: “We know what unchecked wear costs over time: a small inefficiency that eats away at ROI for years. At Jamul, the evidence pointed clearly to assets with productive life still in them.”
“Our job was to restore them properly and give the team the tools to stay ahead of the next problem. At ABB, we don’t just fix what fails. We want to protect what works.”
The initiative also demonstrates the growing relevance of circular economy principles in cement manufacturing, where extending the service life of existing industrial equipment can reduce capital expenditure, material consumption and the environmental impact associated with manufacturing replacement components.
According to ABB, drive reconditioning can reduce lifecycle emissions by 50 to 80 per cent compared with complete equipment replacement. By preserving functional components and restoring critical modules, the process helps retain the economic and material value of existing industrial assets.
The addition of energy appraisals in subsequent phases will further expand the programme beyond equipment restoration, enabling ACC to assess drive performance, identify energy-saving opportunities and improve operating efficiency.
For cement manufacturers, variable speed drives play an important role in controlling motors and optimising energy consumption across production processes. Maintaining their reliability and efficiency is essential for minimising operational disruptions and managing electricity costs.
Vinod Bahety, CEO – Cement Business, Adani Group, said: “Moving from reactive firefighting to a structured maintenance plan was exactly what this operation needed. That kind of peace of mind doesn’t come easily. It comes from a partner that understands how your business runs.”
“We didn’t need a full system overhaul; we needed expert support, actionable insights, and a plan we could execute around our schedule. That’s what we got.”
The project supports ACC’s broader strategy to improve manufacturing efficiency through digital transformation, preventive maintenance and sustainable asset management.
ACC, a subsidiary of Ambuja Cements and part of the Adani Group, operates 20 cement manufacturing facilities and 119 ready-mix concrete plants across India. The company has been advancing initiatives focused on renewable energy, circular economy practices and technology-driven operational improvements.
Alongside Ambuja Cements, ACC is part of a large-scale building materials business committed to achieving net-zero emissions by 2050, with near-term and net-zero targets validated by the Science Based Targets initiative (SBTi).
The Jamul initiative aligns with these sustainability objectives by demonstrating how equipment life extension and digital monitoring can contribute to resource efficiency without requiring large-scale replacement of existing infrastructure.
ABB, a global technology company specialising in electrification and automation, brings more than 140 years of industrial expertise and employs approximately 110,000 people worldwide. Its Motion Services business supports industrial customers through equipment maintenance, modernisation, digital monitoring and lifecycle management solutions.
The agreement also reflects a wider shift in industrial maintenance practices, with manufacturers increasingly adopting predictive technologies to improve equipment availability, manage costs and reduce unplanned shutdowns.
With 25 drives already reconditioned and another 25 scheduled for restoration, ABB’s collaboration with ACC illustrates how targeted modernisation, digital monitoring and circular maintenance practices can extend the operational life of critical equipment while supporting more efficient and sustainable cement production.
