The Abrasion Resistance of Mortars Containing Natural Zeolite Analcime

Abstract

It is always an expectation that to minimize of damage caused by abrasion as a result of increase of abrasion resistance of construction materials. Therefore, the influence of analcime on the abrasion resistance of cement mortars was investigated in this study. Analcime is a natural pozzolan and is one of the valuable minerals of zeolite group. The cement mortars were produced by using blended cements containing analcime. The abrasion losses by friction at the end of 28 days of the mortar mixtures were determined by Bohme surface abrasion tests in accordance with TS 2824 EN 1338. The abrasion tests were carried out to cement mortar mixtures produced with different cement replacement ratio (0%, 10%, 30% and 50%). The results obtained from test series were compared with each other. The test results showed that, abrasion losses of mortars containing analcime were lower than portland cement mortars as 25% approximately. It is believed that this positive effect of natural zeolite in the development of abrasion resistance is due to pozzolanic reactions.
