Abstract :This study aims to investigate the compressive strength of concrete produced with partial replacement of cement with mango seed ash insert ignore into journalissuearticles values(MSA);. The oxide composition analysis of MSA indicates that the Ash is pozzolanic in nature and contains about fifty-eight insert ignore into journalissuearticles values(58.26%); percent of SiCO2. Consistency, setting times, compressive, Slump, Compacting Factor test were carried out on both the fresh and hard concrete. Mix ratio 1:2:4 was used in preparing each of the samples from which nine concrete cubes were cast at each replacement levels of; 0%, 5%, 10%, 15%, 20%, 25%, and 30%. Compressive strength test performed on the cubes at 7days, 14days, and 28days curing periods showed that the strength of the test cubes decreases with an increase in MSA content. The 28days compressive strength of cement-MSA concrete cubes was observed to have attained its highest compressive strength of 23.70N/mm2 at 5% replacement level. The compressive strength result obtained from the partial replacement of cement with MSA is less than that of the control specimen due to weak bonds, light weight and elemental chemical composition of MSA, which was less than that of cement. Some of the advantages to be derived from this partial replacement are; to promote waste management at little cost, to bring about the low capital cost per tonne production compared to cement, to reduce pollution caused by these waste, to promote conservation of lime stone deposit and reduction in CO2 emission.
