Effect of mineral Admixure on self compacting concrete. Mineral Admixure applications in self compacting concrete

      Аннотация: This research work represents a preliminary consider on self compacting concrete (SCC). SCC is a spilling strong mix, that can join under its very individual emerge weight. The basic fluid nature of SCC makes it sensible for putting in gravely structured conditions and in zones with a blocked stronghold. Fly ash can be used as a mineral admixture in concrete. Substitution of fly ash stays to bond in concrete. It is a widely adopted construction practice underlain by the aim to reduce CO2 emissions of cement production. In this examination, cement, fine aggregate, coarse aggregate, water and fly ash materials are used to prepare the SCC. Fly ash replaced with an interval of 10% up to 40%, with the help of polycarboxilic ether based super plasticizer and viscosity modifying admixture to achieve fresh properties of SCC. By using M60 Grade concrete the examinations had carried out by adopting an optimum water-cement ratio. Workability tests on the fresh concrete by using slump flow, T50, V funnel, L box, U box tests and the durability of concrete is tested by chloride attack and sulphate attack at 90 days.
