Rais Khan, CEO, Dynamic Precast, talks about catering to the changing demands of designers and architects with innovative solutions in precast shapes to take India’s construction industry onto the next level.

Tell us about the process of casting concrete in shapes.
In precast, with the help of mould, concrete and steel skeleton, any shape can be cast as required. It may be a designer flower pot, fountain, pole, pillars, drain, covers, garden benches, paving tiles, column, beam, roof, boundary wall or even a complete house. For precasting, the mould could be of cement, wood, Fibre Reinforced Plastics (FRP), aluminium and mild steel.
Concrete mix is prepared in a mixer and then poured in mould, and it vibrates on a vibrating table or by surface and needle vibrator. Demoulding process is done after some time or after complete setting in 24 hours.

Are concrete shapes made with a variety of concrete grades?
Yes. It depends on the product’s quality. As per standard of BIS precast products, cast in different concrete grades from M-10 to M-50 grade.

What are the standard sizes and shapes of precast made by your organisation?
We make paver blocks and chequered tiles as well as cable covers, which are smaller products. Other products are kerbstone, dividers SFRC frame cover, gratings of different sizes, drain with covers of any size, precast and prestressed wall panel with columns, hollow core slabs in heavy and light duty in imported semi-automatic plant, precast toilets, house, prestressed electric poles and spun pipes with septic tank, etc.

Explain the moulds used to make these shapes. Do you customise moulds if the requirement arises?
Always! As our products are for roads, infrastructure and housing, customers have different choices for size, shapes and shades. For that we customise the size and shape of moulds as per choice and selection of the customer. All designers and architects want innovation in their projects. We create as per their requirement.

What are the quality standards followed while making precast shapes?
We have a Quality Manual Plan in our system. Presently, a testing laboratory is active in our manufacturing premise. Regular tests for raw materials and concrete and quality checks are done here using tools, equipment and calibrated testing machines.
Quality checks in our factory starts from system update, raw materials, measurements and weighing process, compaction and ultimately in finished goods. The required curing process used for these products is standard. Channels and sections are not compromised with quality aspects. Quality fabrication is an important part, where we follow the standards.

How does automation and technology contribute towards this process and does that make it less labour intensive?
Automation and technology are very important for the precast industry. Today, there are labour crises in each industry, but in the precast industry, it is too much because of its heavy elements and mostly working in open areas.
While we have a lot of shaded areas in our production premises and many mobile and lifting equipment, it’s necessary to make the system more and more automated.

What are the major challenges you face in the process of making precast shapes and in their transportation?
Major challenges in this industry that we face are in making proper mould to make good quality products or elements as per required by the customer. Secondly, availability of proper raw materials and procurement of subsidiary materials are useful for quality. No doubt packing and transportation of finished products are tough jobs in the precast industry.

How do precast shapes help in the profitability of a construction activity?
In the construction industry, precast elements and products have a big contribution in speedy completion of projects. Projects get finished before time because of precast and prestressed elements. Columns, beams and slabs have a bigger role to play in fast construction and economic growth. In India, acceptability for precast housing is quite slow, but only this industry can fulfil the requirement of infrastructure and housing sector in the country.

What kind of innovations can be seen in the near future in your industry?
The market is moving towards a precast, prestressing system. Systems and equipment are becoming available in the market. High grade concrete and PC wire will change the scenario of this industry. We are preparing for mass housing elements for the middle and low class on a priority basis, especially in towns and rural sectors.

HeidelbergCement India (HeidelbergCement India) has received regulatory consent to establish a cement blending and grinding unit at Village Dongaliya, Tehsil Punasa, District Khandwa in Madhya Pradesh. The consent was granted by the Madhya Pradesh Pollution Control Board under the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981 and is dated 17 May 2026. The company disclosed the development in a filing made under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

The project plan envisages procurement of long term availability of fly ash and the allotment of land on lease for setting up the unit. The proposed facility is described as a blending and grinding installation which will process cementitious materials sourced from nearby operations and suppliers. Company filings state the measures required to secure raw material logistics and statutory compliance before commencing construction.

The addition of a grinding unit in Khandwa is intended to strengthen regional supply and improve logistical efficiency by reducing haulage distances for finished product. The unit is expected to complement existing capacities in central India and to offer flexibility in product mix through blending operations. The reliance on fly ash as a supplementary cementitious material will necessitate long term supply agreements with thermal power producers and coordination with waste utilisation policies.

The disclosure to the regulator and to the stock exchanges follows standard corporate governance practice and aims to keep investors apprised of capital expenditure initiatives. The company indicated that subsequent permits and clearances would be sought in accordance with applicable environmental and land use rules. The project is presented as part of HeidelbergCement India’s broader strategy to optimise capacity distribution and to respond to regional demand dynamics.

The new solution promisescontinuous, real-time tertiary air flow measurement in cement plant operations.

PROMECON GmbH has launched the McON IR Compact, an infrared-based measuring system designed to deliver continuous, real-time tertiary air flow measurement in cement plant operations. The system addresses the longstanding process control challenge of accurate tertiary air monitoring under extreme kiln conditions. It uses patented infrared time-of-flight measurement technology that operates without calibration or maintenance intervention.

Precise tertiary air measurement is a critical requirement for stable rotary kiln operation. The McON IR Compact is engineered to function reliably at temperatures up to 1,200°C and in the presence of abrasive clinker dust. Its vector-based digital measurement architecture ensures that readings remain unaffected by swirl, dust deposits or drift. Due to these conditions conventional measurement systems in pyroprocess environments are often compromised.

The system is fully non-intrusive and requires no K-factors, recalibration or periodic readjustment, enabling years of uninterrupted operation. This design directly supports plant availability and reduces the maintenance overhead typically associated with process instrumentation in high-temperature zones.

PROMECON has deployed the McON IR Compact at multiple cement facilities, including Warta Cement in Poland. Plant operators report that the system has aided in identifying blockages, optimising purging cycles for gas burners, and supplying accurate flow data for AI-based process optimisation programmes. The practical outcomes include more stable kiln operation, improved process control, and earlier detection of process disturbances.

On the energy side, real-time tertiary air data enables reduction in induced draft fan load and helps flatten process oscillations across the pyroprocess. This translates to lower fuel and energy consumption, fewer unplanned shutdowns, and a measurable reduction in NOx peaks. This directly reflects on the downstream cost implications for plants operating SCR or SNCR systems for emissions compliance.
