Mechanical Abrasion of Mortars Containing Clinoptilolite

open access: diamondNevşehir Bilim ve Teknoloji Dergisi, 2019
In this study, it was investigated on the mechanical abrasion of mortars containing natural zeolite clinoptilolite. Bohme surface abrasion tests were carried out to cement mortar samples produced with different cement replacement ratio (0%, 10%, 30% and 50%). The mechanical abrasion of mortars was determined according to TS 2824 EN 1338.
