Experimental Investigations of Partial Replacement of OPC with PFA and GGBS in cement mortar

Production of cement has been identified as a major source carbon dioxide, particulates, and other gases, where it was reported that the production one ton OPC could produce CO2. These gases particulates exert significant effects on human health environment. Therefore, supplementary cementitious materials (SCMs) are becoming sustainable concrete in comparison with ordinary Portland (OPC) by decreasing consumption dioxide emissions. This experimental study is to focus effect partial replacement pulverized fly ash (PFA) ground granulated blast furnace slag (GGBS). Four mixes were used different values PFA GGBS they tested at 1, 2, 4 weeks. The compressive strength these specimens carried out compression test. test results revealed increasing ratios decrease specimens. SCMs mortar ranged from 20 30%, be an acceptable value.
