Abstract

Granite powder is a waste product at many quarries and stone processing plants all over the globe. This waste powder, when properly sieved into an appropriate size distribution, can be used as a suitable reinforcement for geopolymers. The goal of this design was to create a sustainable, cost-effective and reliable structural geopolymer composite utilizing resources that are easily attained worldwide. Its properties and viability as a structural material were determined through four-point flexure testing according to ASTM standards and analyzed by Weibull statistics. Its refractory properties were tested by exposing samples to various temperatures, then testing for shrinkage and flexure strengths. Heat treatment of all samples yielded cracking and warping, but the coarse granite samples maintained strengths over 2 MPa while fine samples maintained 10 MPa strengths. Scanning electron microscopy (SEM) was used to characterize the size and geometries of the granite powder, and to determine its viability as a reinforcement for potassium geopolymer.
