Abstract

Cement masonry units are not considered as sustainable due to consumption of fuel, cement and natural resources and embracing alternatives is mandatory. Geopolymer is a green cementitious material and has excellent mechanical properties, consumes low energy in production and emits less carbon dioxide. The effects of paste volume, proportion of alkaline activator and water/solid ratio were investigated to develop self-standing dry mix of geopolymer hollow block and compared with OPC mix. Factors that require attention in casting geopolymer dry mix are discussed in this article. The optimized mix of geopolymer self-standing dry mix is expected to be found between 30 and 35% of geopolymer paste volume for 7.5% of alkaline dosage and alkaline molar ratio of 1.00.
