鈥淚mprovement in road construction infrastructure, increasing urbanisation rate, and higher investment to boost infrastructure activities serve as the major determinants for the growth of concrete construction equipment in India. With better road transportation infrastructure and a rise in urban population, there exists a greater demand for convenience in personal mobility, healthcare, sanitation, and water supply, among others, which in turn contributes to the boosting demand for construction equipment, attributing to the growth in the construction sector across India,鈥� said Soni.

The Indian market offers a wide selection of batching plants, from both overseas and domestic brands. However, Pramod B Joshi, Additional General Manager (P&M Head, All India), Ahluwalia Contracts India, observes certain features are missing. 鈥淭he water quality should be automatically checked and we also need an indicator showing the quality of concrete 鈥� that is, is it pumpable? Any abnormal size of aggregate coming through the weighing system of the plant should be flagged and the machine should stop automatically. The system of adding ice to the concrete should be simplified. We need more safety features. Incorporating a pollution control system would make the plant more environment-friendly. We also need the plant to show the slump of concrete after it has been mixed, at the time of discharge to the transit mixer.鈥�

As for boom pumps, Joshi says the industry needs 鈥渃ompact boom placers capable of placing concrete at greater heights and boom placers that are economical to use. When the pump starts, it must show the slump of concrete so operators know whether to proceed. Also, the pump must show the quantity of concrete pumped. Lightweight booms and pipelines of a higher quality that last longer are other essentials.鈥�

An expectation that will grow in value in the years to come is the soundproof working of concrete pumps because they are often used in existing or built-up residential areas where noise is a concern, adds Prashant Jha, Chief, Ready-Mixed Concrete & Modern Building Materials, Nuvoco Vistas Corp.

At present, the mixer of RMC plants and the hopper of the boom placer must be cleaned manually, continues Joshi. 鈥淭his cleaning must be automated; it should happen without human intervention. Most accidents happen owing to human negligence at the time of cleaning the mixer. Pumps often break down when the operator hasn鈥檛 properly greased them. As a preventive measure, a pump should not work if it hasn鈥檛 been greased.鈥�

For his part, Satish R Vachhani, Consultant Concrete Technologist, Advanced Concrete & Construction Consultants, would like to see high-quality moisture sensors incorporated in the aggregate and sand bins of concrete batching plants for better control on the water-cement ratio of concrete, the most important factor in maintaining quality of concrete.

鈥淎t present, barely 3-5 per cent of contractors and RMC manufacturers ask for high-quality moisture sensors to be installed in new plants,鈥� he continues. 鈥淏ut moisture meters being installed in concrete batching plants are not very accurate. Now that high and ultra-high grade concrete is being manufactured in most metros, and durability is a major concern, it is imperative to maintain the water-cement ratio as per the mix design parameters. Checking the sand moisture manually once or twice in a shift does not achieve the purpose, especially in rainy weather. Even a very small 2 per cent error can change the water-cement ratio of the mix and marinating W/C is a very important factor in maintaining the quality of concrete. For the best result, microwave moisture sensors may be installed to measure moisture levels in material being discharged from bins, on conveyor belts or vibratory feeders. Sensors are placed directly in the flow of the material, and take 25 measurements per second as the sand and aggregate flows over the ceramic measurement surface. These measurements are then transmitted to the plant control system in real time.鈥�

Vachhani would like major contractors and RMC producers to use rheometers to check the concrete rheology at the concrete mix design stage. Concrete pump manufacturers can help in this for mutual benefit.

鈥淎t present, we are testing concrete for workability and flow properties but the same workability mixes can have different rheology, viscosity and pump pressure and mixes can be finetuned by changing the proportions of ingredients and different PCE-based plasticisers and VMA to address the issues of frequent choking, high pump pressure and pump maintenance,鈥� he explains. 

鈥淗ands-on experience or qualitative estimations of pumpability through simple material tests such as slump and flow tests are insufficient. Concrete pump manufacturers should collaborate and invest in R&D with users like contractors and RMC players to study the effect of concrete mix rheology properties on pump pressure. Intensive research actions in this respect will hopefully bring an improvement in poured concrete quality and performance of equipment.鈥�

The concrete equipment market in India is poised for substantial growth, driven by urbanisation, government initiatives, and infrastructural development. The shift towards automation, sustainable practices, technological integration, and customised solutions are key trends shaping the market. To meet the evolving requirements of the construction industry, manufacturers must focus on delivering high-quality, efficient, durable, and technologically advanced equipment. As the market continues to expand, the emphasis on sustainability and cost-effectiveness will play an increasingly important role in shaping the future of the concrete equipment industry in India.
