Study on factors affecting the mechanical properties of dry mixing CDG based geopolymer

Abstract Cement is the main material for the construction industry. But it produces a large amount of greenhouse gases and consumes a lot of resources. As a new type of green cementitious material, geopolymer materials can replace cement. In order to simplify the preparation process of the geopolymer material, dry-mixing CDG geopolymer materials are prepared by using a dry mixing process technique, using a solid activator material, mixing the dry materials, and adding water to the mixture. In this paper, the completely decomposed granite (CDG) and slag are used as the main cementitious materials, and the geopolymer paste and concrete are prepared by the action of alkaline activator, and the systematic study on the mechanical properties of this new geopolymer material has been carried out.
