Abstract
The use of conventional materials in building construction results in increased emission of carbon dioxide and consumption of more energy. The replacement of sustainable materials with conventional materials can help in reducing the overall energy consumed while making it more eco-friendly. The aim of the study is to replace the cement used in manufacturing of concrete blocks with sustainable and waste materials such as fly ash, ground granulated blast furnace slag and calcined clay. The compressive strength of these blocks were slightly lesser than the conventional blocks while satisfying the standards’ minimum criteria. The blocks showed 50% reduced thermal conductivity and 35% reduced carbon emission, which suggests that these blocks could be an excellent replacement for conventional materials since it increases the thermal comfort of the building while reducing the environmental impact.
