Durability Study on Self Compacting Concrete with Mineral Admixture
Self compacting concrete can be placed and compacted under its own weight without any vibration and without segregation or bleeding. The use of mineral admixture such as fly ash, GGBS, etc. as partial replacement of cement in SCC can bring down cost. The use of industrial waste such as fly ash, GGBS, etc in the binder of concrete reduces the storage, disposal and environmental problems. The most beneficial property with M SAND addition to the concrete in the hardened state are the tensile strength, impact strength, the toughness and the energy absorption capacity. In the present study the mix design for M50 grade SCC was first carried out in accordance with EFNARC guidelines. The cement will be replaced with GGBS and fine aggregate get replaced with manufacturing sand Test such as slump flow,V funnel were carried out on fresh concrete and the optimum dosage of super plasticizer was found and cubes were cast for 7,28,56 days for the mix ratio 1 1.40 1.27 0.34. The influence of GGBS on the workability, mechanical strength and durability aspects like water absorption test, sulphate attack test, acid resistance test,rapid chloride penetration test , sorptivity test , linear polarization resistivity test and alkalinity test of self compacting concrete are studied.
