India: A Bangalore-based startup formed at the Indian Institute of Science (IISc) has developed an ‘eco-friendly’ cement alternative using geopolymer technology. The product claims to reduce CO₂ emissions by 21.5kg/m2 of pavers produced compared to ordinary Portland cement, according to The Economic Times. It also claims to eliminate water use and offer a 15-20% cost advantage. The product achieves full strength in just three days, compared to the 28 days required for Portland cement.
Nanjunda Rao, one of four cofounders of Novacret and chief research scientist at IISc, said “The benefits are significant, geopolymer-based materials achieve full strength in just three days in tropical climates like India, compared to the 28 days required for Portland cement.”
