Abstract
Crushing strength of granular material plays vital role in major civil engineering structures like offshore constructions, pile driving, mining under the high stresses. Determining the crushing strength of granular materials and also experimental results get influenced by its size, shape of grains, density, load application, strain rate, and its aspect ratio etc. So, crushing strength value differs from material to material. With this in view, here an attempt is made to determine the crushing strength for different granular materials like Natural River sand, Ennore sand, Glass beads and Geopolymer fly ash sand with specially fabricated mold. All materials are tested and characterized for index and engineering properties and also determined crushing strength by strain controlled digital load frame for different aspect ratios. Similar crushing strength values obtained for 12M Geo-polymer sand compared to other granular materials hence Geopolymer sand as an alternative material to natural river sand. Experimental results are tabulated in the paper.
