Abstract
Traditional concrete used within the manufacture of High-Performance Concrete (HPC) does not provide the essential consistency. To attain the expected workability, structural reliability, high strength, but durability under adverse environmental conditions, generally available concrete materials must be perfectly shaped to a significant level. available Metakaolin (MK) and Rice husk ash (RHA) acquired were used to replace cement by 0%, 5%mk + 10%rha, 7.5%mk + 10%rha, 10%mk + 10%rha, 5%mk + 12.5%rha, 7.5%mk + 12.5%rha, 10%mk + 12.5%rha, 5%mk + 15%rha, 7.5%mk + 15%rha and 10%mk + 15%rha of its weight in different proportioning. Integration of MK and RHA into concrete increases water requirements, when compared with the control ordinary Portland cement (OPC) blend, integration of MK and RHA greatly improves durability properties; thus, by use of MK and RHA will decrease cement consumption while improving the durability characteristics of concrete such as percentage of water absorption, sorpitivity test, effective porosity, permeability, resistance to acid and rapid chloride penetration tests. Hence, this research paper concludes with strength characteristics and durability parameters for MK and RHA based High Performance Concrete (HPC) mixes.
