摘要：

As a relatively new material, geopolymer concrete offers benefits as a construction material for sustainable development. It utilizes waste materials such as recycled concrete sludge, fly ash, etc. It has a very low rate of green house gas emission when compared to ordinary Portland cement. In this study, the components of a geopolymer are concrete sludge and metakaolin, NaOH was used as an alkaline activator. The amount of water glass and the ratio of NaOH/water glass were varied to find an optimal value. To improve the mechanical properties, silica fume was added as a bonding matrix, and the specimens were cured in air, then their mechanical properties such as compressive strength and bending strength were measured and their microstructures were investigated.
