The Manufacture of the Grinding Wheels Based on the Ca–K Geopolymer Matrix

This article describes the successful manufacture of new grinding wheels based on a binding agent from a clay substance and blast-furnace slag (the Ca–K geopolymer matrix) on industrial presses. Trained factory staff of the company Best – Business, a.s. tested the pressing process for the manufacture of geopolymer-bonded wheels and verified their quality by factory control equipment (Grindo Sonic and Zeiss-Mackensen methods, test of the safe peripheral speed). The results have shown that the Ca–K geopolymer matrix is suitable for grinding-tool preparation and the grinding-wheel properties are comparable with similar products based on the fired ceramic binding agent.
