Development of Eco Friendly Cement Concrete Using Ground Granulated Blast Furnace Slag

摘要

Cement is the most commonly used construction material. Now, cement production is increasing rapidly. In order to minimize the production and usage of cement, an alternative solution is to be implemented as either or partial replacement of cement. GGBS is the waste byproduct produced during the manufacturing of Steel. GGBS is used as a replacement for cement for every 5 and the optimum mix is found out by studying the mechanical properties. Replacement of GGBS was carried out up to 50 against cement. The presence of GGBS in the concrete mix exhibits notable achievement in the compressive strength of the concrete, however the presence of GGBS reduces the performance of concrete in split tensile stress and flexural stress due to increase in brittleness of the material. Modulus of elasticity of GGBS concrete shows prominent performance when compared with conventional concrete. From the above mixes, GGBS with 45 replacement against cement in concrete shows a better performance.
