Description
Summary:– Geopolymer concrete is an effective alternative to reduce adverse impacts of cement manufacturing on environment and achieving sustainable development. Road construction is a major sector, which utilizes concrete in large volume, having significant effect on environment. The present work is presented in two parts. In the first part, evaluation of CO 2 emission for 1m 3 of geopolymer and ordinary Portland cement concrete has been carried out and further compared. In the second part the results of first part are used to evaluate the CO 2 emission for various types of road construction, National highway, State highway, Major District Road, Other District Road, Village Road for 1km of road. About 18 % of reduction in CO2 emission can be obtained by using geopolymer concrete instead of ordinary Portland cement concrete in road construction, just in 1km of stretch. Significant reduction in CO 2 emission can be obtained in road sector by utilising geopolymer concrete leading to sustainability.
