An Experimental Study On Effect Of Ratio Of Different Sized Coarse Aggregates On Compressive Strength Of Self Compacting Concrete

GEORGE LEO ANAND. G

Abstract


Concrete is the most widely used man made material, with constituents of cement, fine aggregate, coarse aggregate and water. In which the coarse aggregate occupies three fourth of the volume of concrete and influences the properties and performance of concrete with various physical, chemical and thermal properties. In this study an attempt is made to investigate experimentally, the effect of various nominal maximum sizes of coarse aggregate (10mm, 12.5mm, 16mm and 20mm) in concrete. Specimens were prepared with concrete designed using IS method. To study the fresh concrete properties tests are conducted such as slump, Vee-Bee and Compacting Factor. To determine the properties of hardened concrete, tests such as Compression, Tension and Flexure are conducted. It is concluded that the fresh and hardened concrete properties are increased with the increase in nominal maximum size of coarse aggregate.
