Comparative Study of the Mechanical Behavior of Self Compacting and Conventional Concreteswith Strength of 20-80 MPa

Abstract

The aim of this study is to find a correlation between strength of different concrete specimen shapes and sizes of self-compacting concrete, to evaluate the mechanical properties (compressive strength, splitting tensile strength and modulus of elasticity) and compare them with conventional concrete. Self-compacting concrete mixes and conventional concrete mixes with different compressive strengths (20, 40, 60 and 80)MPa are used to determine the effects of: compressive strength, splitting tensile strength and modulus of elasticity on these relations. Water curing condition is used and the age tests are 7, 28 and 90 days for self-compacting concrete and 28 days for conventional concrete. The result obtained from this study indicates: The difference between results of cylinders/cubes of self-compacting concrete compressive strength are lesser than the difference of conventional concrete related to the slenderness of specimens.
