ACI defines HPC as the concrete that meets special performance and uniformity requirements that may not always be obtained using conventional ingredients, normalmixing procedures and typical curing practice. These requirements may include enhancement of ease of placement without segregation, long term mechanical properties, early age strength, toughness, volume stability and life in severe environments. Secondary raw materials (SRM) have a very significant role indetermining the overall response of any modern concrete.The SRM's that were seclected, included limestone powder, fly-ash, silica...
