摘要：

In this study, the influence of crumb rubber on the properties of geopolymer mortar was investigated. The crumb rubber was used as fine aggregate to reduce consumption of natural river sand. The rubber replacement levels namely 10%, 20%, and 30% by volume of the sand was chosen. The results were compared with the control specimen made with only river sand. It was found that the compressive strength of mortars was decreased with increasing the crumb rubber content. An increase in water absorption was observed. However, the strength of the paving block specimen made with 10% rubber meets the requirements for application in interlocking paving blocks. Its compressive strength at the age of 7 days was 85.0 MPa. Disciplinary: Civil Engineering & Material Technology (Cement, Geopolymer, Construction Materials, Pavement).
