Our Research Group

The mission of the MatERIAL Group is to contribute to India's stride of transitioning into low-carbon economy through innovation in material development and design. The long-term vision of the group is to create a lasting impact on the built environment through enhanced durability and reduced environmental impacts.

Transitioning to low- and zero-carbon building and construction materials is complex because of the size, significance and emissions associated with this sector. Construction contributes to 9 - 10% of India's GDP with consumption of cement increasing steadily over the last few years barring the effect of COVID in 2020 - 2021. Cement production is associated with 8% of global carbon dioxide emission besides several other environmental impacts. However, the transition to low-carbon built environment has begun, necessitating actions from agencies and material manufacturers to produce low-carbon durable concrete with reduced environmental impacts.

 

The Centre for Sustainable Technologies (CST) has a long-standing record of making societal impacts through innovation in sustainable material and energy technologies. As part of CST, MatERIAL Group is rightly positioned to continue efforts in developing sustainable material technologies that support the country's push towards a "green" future.

 

MatERIAL Group is at the forefront of addressing these challenges through innovation in low-carbon concrete and smart constructions. We have expertise in formulating cementitious composites using a range of synthesized biomaterials and inorganic fillers, which enhance carbon sequestration, self-healing and durability under aggressive environments. The group PI has lead development of several cutting-edge building material technologies, to name a few, i) engineering additives and material porosity to enhance carbon sequestration and stability, ii) modifying composition to enhance self-healing of cracks under multiple loading cycles, and iii) tailoring particle size distribution of bio-based and lightweight additives to improve rheology, hydration and durability under elevated temperature conditions and aggressive fluids.

 

Building up on the existing expertise, the group is now involved in additive manufacturing of materials of special designs and compositions (for example, using alternative binders), that can remediate the environment, improve durability and promote smart functionalities in buildings.
