Nuvoco came in the light when it acquired L&T?? ready-mix concrete business in 2008. Since then it has established itself not only as a cement producer but a player with innovative construction materials. It has successfully transformed itself from cement manufacturer to a building material supplier with a wide range of products. Prashant Jha, Chief of Ready Mixed Business, Nuvoco, speaks on one of the innovations he has recently launched.

Explain the idea behind introducing a new product during the pandemic. What is the market size, and what kind of growth do you expect from this product?

Through our interactions with customers and market studies, we observed that the construction industry is facing challenges of manufacturing concrete at the site due to the non-availability of superior quality raw materials like cement, sand, and aggregates. In the current scenario, the majority of small concrete work is done by mixing cement, aggregates, and water at the site. Then there is the issue of wastage of raw materials.

Most of the sites are still using the volumetric batching method, which generally results in poor quality concrete at site. Further due to the pandemic situation, there is a shortage of labour, moreover getting labour to do small jobs is generally a problem. All these factors resulted in an increased demand for well-graded pre-mix bag concrete. Although there are no published records, we are estimating the all India market size is more than 10,000 tonne per month, and it would be growing at 15 per cent per annum.

What is the manufacturing process ??is it the same as wet concrete? What is the batch size?

InstaMix Xpress is a pre-blended mixture of cement, sand, and aggregates with special admixtures, requiring only the addition of water before pouring the concrete. It is produced in a controlled environment and is fast, easy-to-use, and ready-to-pour in just three steps ??open, mix, and pour.

One needs to do is open the bag in a pan or mechanical mixer as per the requirement; add four to five litres of potable water per bag and mix the concrete uniformly; and finally, pour the preparation without making a mess. The manufacturing process of Instamix Xpress is entirely different as compared to wet concrete. In InstaMix Xpress, we have to ensure that there is 0 per cent moisture at any stage of production till packaging of the product. It is available in 50 kg special moisture-proof sealed bags, which are tested for quality. Batch size depends on the transit mixer capacity, which varies from 500 kg to 2,000 kg.

Is there any shelf life for the product?

Yes, it is good for use till three months of production.

Is the product covered under any BIS code? OR is the code in the draft stage?

No at this stage it is not covered under any BIS codes; however drafting of code for dry concrete is under process.

What has been the response from the users?

Initially, we have launched InstaMix Xpress in East and Northeast markets and the response is very encouraging. Structural consultants and contractors prefer to use the M-30 and M-40 grade of concrete, which is not possible to produce at the site and ready-mix concrete is not available in remote areas. InstaMix Xpress is an ideal solution as it is a pre-mixed, ready-to-use, bagged, dry concrete, which can be easily transported to these far-flung areas. Looking at the response, we are planning to launch this product in Northern and Western India very soon.

Does any other cement manufacturer cater the consumers with a similar product?

Yes, a few cement manufacturers tried to produce at the local level ready-mix plants but they were not able to control the quality of the product.

To what extent the strength will be compromised if more water is used or if the product is used beyond stipulated period?

It all depends on how much excess water has been added or how long InstaMix Xpress has been stored beyond the three months shelf life. We recommend using four to five litres of water per 50 kg bag (depending on the grade of concrete). If the product is used beyond the stipulated period, [definitely] the compressive strength will reduce from 10 to 50 per cent.

The Department of Civil Engineering at Dhanekula Institute of Engineering & Technology, Ganguru, organised an industrial interaction programme under the Adani FutureX Programme on Thursday. The programme focused on strengthening engagement between the institute and the cement industry while giving students greater exposure to professional practices.

Yedukondalu, technical head for Andhra Pradesh and Telangana at Adani Cement, delivered a technical lecture on concrete as a man-made material. The session covered the importance of concrete in construction, its properties and applications, and its significance in modern infrastructure development.

The lecture also addressed the role of quality cement and suitable concrete technology in supporting durable and sustainable construction. The discussion connected classroom learning with the technical considerations involved in infrastructure projects and construction practices.

A key part of the programme was the signing of a memorandum of understanding (MoU) between the Department of Civil Engineering and Adani Cement under the Adani FutureX Partnership Agreement. The agreement is intended to strengthen industry-academia collaboration through opportunities for student internships and industrial visits.

The initiative is expected to provide students with practical exposure, improve their understanding of industrial practices and help bridge the gap between theoretical knowledge and real-world applications. Dhanekula Institute Chairman Dhanekula Ravindranath Tagore, Secretary Dhanekula Venkata Bhavani Prasad and Director DKRK Ravi Prasad supported the initiative, with the institute leadership highlighting the importance of industry-institution interaction in enhancing students’ technical employability.

JK Lakshmi Cement has laid the foundation stone for Project Kamakshi, its first integrated cement manufacturing facility in Assam, marking the company’s entry into Northeast India. The groundbreaking ceremony took place at Umrangso village in Dima Hasao district in the presence of Assam Chief Minister Himanta Biswa Sarma.

The project involves an investment of Rs. 110 bn, including the mining lease. It will have annual cement production capacity of 2.5 mn t and a 1 mn t clinkerisation unit, with completion scheduled for FY2029.

The facility is expected to create more than 2,000 jobs and will primarily serve the growing Northeast market. It will also include dedicated railway sidings for transporting raw materials and finished cement, supporting supply chain reliability and regional distribution.

Chairperson and Managing Director Vinita Singhania said the project represented the beginning of a long-term relationship with Assam and the wider Northeast. She said the plant would help provide locally produced cement, employment and dependable supplies as the region’s infrastructure development accelerated, while enabling the company to grow alongside the communities it serves.

The investment supports JK Lakshmi Cement’s strategy of expanding into high-growth markets beyond its established presence in Northern, Western and Eastern India. The company expects the project to contribute to regional economic development and infrastructure growth while pursuing its long-term objective of achieving net-zero emissions by 2047.
