Initial Studies on the Mechanical Properties of Geopolymer Mortar after Additive Stone Powder Treatment

Xiem Nguyen Thang


Concrete is the most commonly used construction material. Its use by communities across the globe is second only to water. Geopolymeric binders appear to be an alternative to ordinary portland cement (OPC), due to high mechanical performances and environmental advantages. However the cost of geopolymer binders is still higher than OPC, it is one of the major factors explaining why this new product is not yet a current alternative. So the purpose of this research was reduced the cost of geopolymer binders by addition stone powder (SP) content but mechanical properties of mortar is still good enough to meet essential requirements of industries. In order to determine the optimal proportion of stone powder content in mortar, the influences of ratio of stone powder/geopolymer cement (SP / GC), effects of stone powder on mechanical properties of mortar were investigated in this study.
