Experimental Study on Self Compacting Concrete Using Partial Replacement of Cement by Corncob Ash

Self Compacting Concrete that is able to flow under its own weight and completely fill the form work, even in the presence of dense reinforcement, without the need of any vibration, whilst maintaining homogeneity).SCC can also be used in situations where it is difficult or impossible to use mechanical compaction for fresh concrete, such as underwater concreting, cast in-situ pile foundations, machine bases and columns or walls with congested reinforcement The composition of SCC is similar to that of normal concrete but to attain self flow ability admixtures, such as fly ash, glass filler, limestone powder, silica fume, Super-pozzolonas, etc; with some superplasticizer is mixed.The addition of corncob ash can improve ductility, post crack resistance, energy absorption capacity and bleeding resistance. .The various properties of the materials to be used in the experimental programme were determined.The specifications of glass corncob ash and the advantages of using them along with concrete were studied.A detailed review of literature on glass powder concrete was also done.Cement will be replaced with corncob ash by 5%, 10%, 15%, 20%, 25%, to the weight of cement.The cubes, cylinders and prisms were casted of size 150x150x150mm, 150mm diameter x 300mmhigh, 700x150x150mm.Superplasticizer will be added for better workability and optimum dosage was determined by using marsh cone test.Thus various strength and durability test will be conducted.
