Abstract: HPC can be produced by incorporating fine ground solid materials like Metakaolin and RHA to strengthen the interfacial transition zone and chemical admixtures and also reduces the ratio between water to binder. The pozzolanic reactivity of rice husk ash and Metakaolin are very low at initial ages. So for the production of HPC, along with metakaolin and rice husk ash when silica fume is combined, the slow rate of hydration RHA and metakaolin will be compensated by the silica fume to have a better early strength. Hence, the effect of RHA and Metakaolin is combined together to get the quality of sturdiness attributes of HPC. The fatigue strength of HPC is compared for both the materials.
