EXPERIMENTAL INVESTIGATION ON MODULUS OF ELASTICITY OF SELF - COMPACTING CONCRETE

Concrete is a mostly used construction material in the world. As the use of concrete becomes more widespread, the specifications of concrete like durability, quality, compactness and optimization of concrete becomes more important. Self-compacting concrete (SCC) is a very fluid concrete and a homogeneous mixture that solves most of the problems related to ordinary concrete. Self-Compacting Concrete gets dense and compacted due to its own self-weight. An experimental investigation has been carried out to determine different characters like workability and strength of Self-Compacting Concrete (SCC). Test involving various fly ash proportions for a particular mix of SCC. Test methods used to study the properties of fresh concrete were slump test, U – tube, V – funnel and L – Box. The property like modulus of elasticity of SCC was also investigated. The stress-strain relationship was studied for the M20 concrete mix using cylinders of size 150mmX300mm. The specimens were cured and tested for 7 and 28 days. Test Results shows that the workability characteristics of SCC are within the limiting constraints of SCC. The variation of different parameters of hardened concrete with respect to various fly ash contents was analysed.
