Abstract

Temperature rise during cement hydration is still a major problem in the construction of bulk concrete structures. The internal temperature of bulk concrete increases due to the cement hydration process while the external concrete may be cooling and shrinking. When the temperature varies significantly across the structure, it can cause cracks in the concrete. Also, high temperatures can delay the formation of ettringite and reduce the strength and durability of concrete. Replacing natural pozzolans is one of the most effective methods to reduce thermal stresses and control cracking. In this research, the aim is to design cement to make self-compacting bulk concrete with high strength (C50). Based on this and after checking the conditions of the country and the availability of the best natural pozzolan, iron smelting furnace slag and microsilica were used as alternative pozzolans. Thus, three two-component cements with 35%, 40% and 45% replacement of slag and a three-component cement containing 45% slag and 6% microsilica were investigated. For the design of these cements, after conducting physical and chemical tests of cement and cement mortar, the required technical parameters obtained by polling concrete technology experts were checked. The results showed that slag can play an essential role in improving the mechanical, workability and thermal properties of concrete. Based on the results, cement with 45% slag had the best performance.
