Abstract

In this study, influence of blended cements produced with different types of pozzolans on sulfate resistance of concrete was investigated. For this reason, Manisa Enli Mining crushing waste natural zeolite (clinoptilolite) and two different types of volcanic tuff supplied from Eskisehir and Nevsehir region were used in blended cement production According to mechanical performance of these blended cements, sulfate resistance experiments were carried out in accordance with ASTM C 1012 code. The mechanical properties of the blended cements were determined on 40x40x160 mm mortar specimens. The 25x25x285 mm mortar bar specimens were produced in order to determine the length changes of the specimens under sulfate attack. Mortar bar specimens were cured in 10% Na2SO4 solution for 6 months. The length changes and mechanical properties of the mortar specimens with different types of blended cements showed that, zeolite and volcanic tuffs reduces the ettringite formation when compared with ordinary CEM I 42.5 reference specimens.
