STUDY OF STRENGTH AND DURABILITY ON HIGH STRENGTH CONCRETE BY PARTIALLY REPLACING CEMENT WITH GGBS AND FLY ASH OVER ACID ATTACKS

Concrete is most extensively used material in construction. CO2 is emitted during the manufacture of cement, damaging the environment. By lowering cement usage leads to reduction of CO2 generated. The increasing demand for cement made researchers to think about the supplementary materials for partial replacement of cement. In the same case if these supplementary materials are naturally occurring or any industrial wastes, then it results in both environment sustainability and economical. These materials are called as pozzalonas, which exhibit cementetious properties when combined with calcium hydroxide. Many research works state that materials like fly ash, GGBS, silica fume, metakaolin can be used as partial replacement for cement. The present work focuses on investigating characteristics of M60 grade concrete with partial replacement of cement with GGBS and fly ash. GGBS replacing cement via 10%, 15%, 20% and fly ash replacing cement as 5% constant. The cubes, cylinders and prisms are tested for compressive strength, split tensile strength, flexural strength. Durability studies with sulphuric acid and hydro chloric acid were also conducted.
