This study examins the some experimental works to distinguish the characteristics of concrete mixtures using blended cement; slag cement and ternary cement. In this study, 40%, 50% and 60% replacement ratio of blast furnace slag(BSF) to OPC are used, also 35:45:20, 30:35:35, 30:40:30 and 35:40:25 ratio of OPC:BSF:FA are used. The characteristics tests include slump, air content, compressive strength and thermal properties of concrete. The compressive strength tests are executed at the age of 3, 7, 28, 56, and 91 days. The coefficient of chloride diffusion is determined by NT Build 492 method. |
