REDUCTION OF GREENHOUSE GAS EMISSION BY CARBON TRAPPING CONCRETE USING CARBONCURE TECHNOLOGY

Abstract

The growing concern about climate change and global warming, resulting from the increased concentration of carbon-di-oxide in the atmosphere has created considerable interest in carbon sequestration. Carbon is usually sequestered in the ocean or deep in the earth's crust. but these processes require a lot of time and need additional energy investment for carbon to be sequestered. It is noted that cement industries contribute to 7% of global CO2 emission and it's estimated that 50% of global cement production will be from India and china by 2050. Also in the current time when trees are being cleared for construction of the building, which is estimated to release 1.5 billion tons of CO2 into our atmosphere every year. Some measures must be taken to give back to the environment. Thus if carbon is stored in concrete it is likely to stay for a longer time. The carbon cure technology enables the production of some reliable concrete but with the reduced carbon footprint. The technology injects a precise dosage of CO2 in concrete during mixing where it mineralizes. The mineralized CO2 improves the concrete compressive strength, enabling reduced cement content in their mixes and achieve further carbon reduction without compromising quality. Concrete made with carbon cure technology provides 4-6% reduction to the global warming potential
