Silica fume is added with OPC to enhance the strength of HSCC. 50% of fly ash and 50% of GGBS are used for making HSGC. OPC 53 grade cement was chosen for making HSCC. The specific gravity of cement is 3.15. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600 kg/m 3.
