Modular Concrete Curing: A green alternative to curing process

Published

Shares

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.

Indian Steel Ministry Seeks $1.7 Bn for Low-Carbon Steel Production

India is actively working on a green steel policy

India’s Ministry of Steel has requested 150 billion rupees (approximately $1.74 billion) from the federal budget to incentivise mills to produce low-carbon steel, according to two government sources familiar with the matter.

As the world’s second-largest steel producer after China, India is actively working on a green steel policy aimed at reducing emissions in steel production. This initiative forms part of the country’s broader efforts to meet its net-zero target by 2070, as outlined by Prime Minister Narendra Modi.

The steel ministry plans to use the funds to offer incentives that encourage emissions reduction, improve research and development, increase raw material efficiency, and incentivise banks to offer lower interest rates on renewable energy loans. These details were shared by the sources, who requested anonymity as the discussions are private.

The steel ministry did not respond to an email seeking comment.

Once the funds are allocated, the ministry will submit the proposal for the cabinet’s approval. In December, the government defined ‘green steel’ as steel produced with emissions lower than 2.2 metric tons of CO2 per tonne of finished steel.

The proposed incentives would remain in place until 2030, with green steel potentially being used in government projects.

India’s steel production generates 2.55 metric tons of carbon dioxide per tonne of crude steel, 38% higher than the global average of 1.85 tons, according to Global Energy Monitor.

Cement Industry Needs 35-45% Emissions Cut for Net-zero by 2070

This need was highlighted at a workshop organised by NITI Aayog at Vigyan Bhawan.

The Indian cement sector, responsible for 5.8 per cent of the country’s total CO? emissions, requires the adoption of carbon capture, utilisation, and storage (CCUS) technologies to achieve a 35-45 per cent reduction in emissions and meet the net-zero target by 2070. This need was highlighted at a workshop organized by NITI Aayog at Vigyan Bhawan.

Titled “Carbon Capture, Utilization, and Storage (CCUS) in the Indian Cement Sector,” the workshop brought together government officials, industry leaders, researchers, and academicians to discuss decarbonisation strategies. The Indian cement industry, with an installed capacity of 600 million tonnes and an annual production of 391 million tonnes, plays a critical role in the country’s infrastructure development and economy.

Prof Ajay Kumar Sood, Principal Scientific Adviser to the Prime Minister, stated that CCUS is an essential tool for addressing emissions in the cement sector, which is crucial for meeting India’s long-term climate goals. He stressed the need to balance economic growth with environmental targets and advance research and development to overcome challenges in decarbonizing this hard-to-abate sector.

Dr VK Saraswat, Member of NITI Aayog, noted that the cement industry is a key player in the Asia-Pacific region, which is witnessing rapid growth in the global cement market. He emphasised that carbon capture and utilization technologies, along with clean energy initiatives, are vital for reducing emissions in the cement sector. He also highlighted the role of carbon pricing and climate finance in supporting decarbonisation efforts.

India holds significant potential for CCUS, with regions like the Krishna-Godavari Basin, Deccan Traps, and mature oil and gas fields offering substantial CO? storage capacity. Innovative utilisation pathways, such as producing methanol, biodegradable plastics, and value-added chemicals, were discussed as potential solutions for creating a low-carbon future.

Pankaj Agarwal, Secretary of the Ministry of Power, shared that the government is preparing a comprehensive CCUS Mission to support these efforts. Ranjith Rath, CMD of Oil India, emphasised the need for innovative solutions and geo-sequestration techniques to mitigate emissions effectively.
