Prediction of Heat Evolution of OPC Blended With Silica Fume Using A Multi-Component Hydration Model

Abstract

Due to the pozzolanic reaction between calcium hydroxide and blended components, compared with ordinary Portland cement, hydration process of blended Portland cement is more complex. In this paper, based on a multi-component hydration model, a numerical model which can simulate heat evolution process of OPC blended with silica fumeis built. The influence of water to cement ratio, curing temperature, particle size distribution of cement, and cement mineral components on heat evolution process is considered. The prediction result agrees well with experiment result.
