Indian Institute of Science (IISc) scientists in Bengaluru have devised a construction material that can partially replace natural sand. IISc's Centre for Sustainable Technologies (CST) is investigating ways to repurpose industrial waste gas CO2.
They use CO2 to turn excavated dirt and construction waste into sand. The research shows that incorporating CO2-treated building waste in a mortar and curing it in a CO2-rich atmosphere increases strength development.
This revolutionary method boosts compressive strength by 20-22%. The researchers have also investigated using collected CO2 to build cement-lime-soil composites that might replace half of the mortar's tiny particles. They also made 3D-printable materials from stabilized excavated soil and cement, slag, and fly ash. Research on how industrial flue gas affects these materials' qualities may enable industrial uses and possibly revise cement-based construction material regulations.

Technology is a useful servant, but a dangerous master, it was rightly said. Electronic devices have grown into an inevitable part of our daily lives.
