Modular Concrete Curing: A green alternative to curing process

The traditional process of curing concrete is cumbersome, requires extensive labour work and leads to significant quantities of water loss. Ambuja has introduced a waterless curing technique in India that is economical and environment friendly.

Any cement concrete product or structure has to go through a curing process when the product or structure gains strength. The process of curing is done mainly with water. The chemical action between cement and water helps in hardening of concrete.

Curing must be done for a certain period of time so that concrete achieves its potential strength. It is very important to do curing properly as it crucial for the strength and durability of the concrete product or structure. The amount of time curing is to be done depends on the purpose of the concrete product or structure, temperature and humidity of the atmosphere.

Traditional curing process

Traditionally, curing is done by pouring or spraying water on concrete or mortar surfaces for an adequate period of time. Water has to be continuously replenished as and when it evaporates due to high temperature and low humidity. If the water dries out the strength of the concrete structure or surface will be impacted.

On flat surfaces such as pavements, roads, sidewalks and floor slabs curing is done by ponding water on the exposed top surface. This is done by making small bunds a few hours after the concrete work is over.

Typically, masons and labourers build bunds with cement and sand on flat concrete surfaces. Water is then poured on the surface and retained for a few days. On surfaces that cannot hold water, labourers spray water several times during the day for several days.

History and description of the technology

Ambuja Cements has come up with an alternative to combat difficulties in managing the traditional method of curing, the Ambuja Modular Curing Solution (AMCS). AMCS entails the use of a plastic sheet to prevent water losses due to evaporation, protects against strong winds, low humidity and high ambient temperatures.

How it can be used/ installed

Surfaces, which are concreted or cemented, are covered by plastic sheets primarily to prevent loss of humidity. All that the contractor has to do is to inform the service providers at Ambuja. The site engineer from Ambuja visits the premises where concrete is being poured and makes necessary arrangement at the site to cover the laid concrete. Once concrete is poured the cover is laid on top. The polymer covering comes in standard sizes that can be joined end to end to make a larger sheet. The joint is strong and water tight and does not let water or moisture to seep out. It is a quick and hassle free process.

Advantages for the construction industry

The biggest benefit is saving of water. About 12,000 litres of water required for curing 100 square metres of slab surface could be saved on an average. In India, many places are extremely hot and arid. Water availability is a serious issue. Under these circumstances curing process is not always done well. Also, labourers are required to build bunds on cemented surface or spray water several times during the day. Many a times the slab may have dry patches due to inappropriate/insufficient water application on the surface. AMCS is a service that helps reduce water usage and lower labour and other costs.

Its availability in India

At present AMCS is a service and is being expanded through its channel partners. The response to AMCS has been quite encouraging as curing is done effectively without hassles, water or labour. For Ambuja Cements, AMCS is yet another initiative towards sustainability.

JK Lakshmi Cement has recently laid the foundation stone for Project Kamakshi, its first integrated cement manufacturing facility in Assam, marking its entry into Northeast India. The groundbreaking ceremony was held 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 billion, including the mining lease, and will have an annual cement production capacity of 2.5 million tonnes, supported by a 1 million tonne clinkerisation unit. Scheduled for completion by FY2029, the facility is expected to generate employment for over 2,000 people while catering primarily to the growing Northeast market.

The integrated plant will feature dedicated railway sidings to facilitate efficient transportation of raw materials and finished cement, strengthening supply chain reliability and regional distribution.

Vinita Singhania, Chairperson and Managing Director, JK Lakshmi Cement, said, “”Project Kamakshi is the start of a long-term relationship with Assam and the wider North East. This is a region that is building fast, and it deserves quality cement made close to home. With this plant, we want to bring scale, jobs, and dependable supply to the region. At JK Lakshmi Cement, we believe that building a stronger India goes beyond infrastructure. It is also about growing together with the communities we serve.””

The investment aligns with the company’s strategy to expand into high-growth markets beyond its established presence in Northern, Western and Eastern India. The project is also expected to support regional economic development and infrastructure growth.

JK Lakshmi Cement aims to pursue its expansion plans while working towards its long-term target of achieving net-zero emissions by 2047.

JK Lakshmi Cement has deployed more than 70 electric vehicles (EVs) across its logistics network and plans to increase the fleet to 120 vehicles by March 2027. The expansion is part of its decarbonisation strategy, which aims to reduce transport-related emissions and improve operational efficiency.

The company has achieved nearly 100 per cent EV-based clinker dispatches from its Sirohi plant in Rajasthan to the Kalol Grinding Unit in Gujarat. The transition marks an increased use of electric mobility for long-haul cement transportation and is intended to lower the environmental impact of logistics operations.

The existing fleet operates on routes connecting the Sirohi plant with the Kalol Grinding Unit, Palanpur Unit and Surat Grinding Unit. JK Lakshmi Cement is working with electric vehicle logistics providers SwitchLabs and Billion E to support fleet deployment and manage transportation requirements across these routes.

The company expects the planned expansion to increase the use of electric mobility throughout its logistics network for moving cement and clinker. Chairperson and Managing Director Vinita Singhania said the programme reflected the integration of sustainable practices with the company’s focus on long-term business efficiency, while describing the Sirohi–Kalol transition as an important step in its wider decarbonisation strategy.

The EV programme forms part of JK Lakshmi Cement’s green logistics and sustainability roadmap, alongside initiatives to improve efficiency and reduce emissions across its value chain. The company has set a long-term target of achieving net-zero emissions by 2047. It is part of the JK Organisation and operates integrated cement plants in Rajasthan and Chhattisgarh, along with grinding units in Gujarat, Haryana and Odisha. The company has an annual turnover of more than Rs. 60 bn, combined cement capacity of approximately 18 mn t per annum and a target to raise capacity to 30 mn t by 2030. Its portfolio includes ready-mix concrete, gypsum plaster, wall putty, primer, adhesives and fly ash blocks.
