EFFECTS OF NATURAL ZEOLITE PARTICLE SIZE ON THE CEMENT
Journal Title: Structure and Environment - Year 2017, Vol 0, Issue 3
Abstract
This paper reports the test results of the Transcarpathian zeolite grain size on the cement-zeolite pastes properties. Materials used in this study included CEM I 42.5R and the zeolite chiefly composed of clinoptilolite. Tests were performed to determine the setting times, hydration kinetics and phase composition of pastes, and the consistency and compressive strength of mortars. It was demonstrated that the degree of fineness of zeolite had a significant effect on its pozzolanic properties, thereby affecting the properties of mortars. Depending on the zeolite gradation, the compressive strength of mortars can increase or decrease. Likewise, the zeolite fineness can contribute to higher or lower flowability of mortars compared to the mortars without the mineral additive.
