【 摘 要 】

The application of Self-Consolidation concrete is needed for casting the concrete element with close-fitting reinforcement. This study was conducted to examine the effect of fly ash utilization on Self-Consolidation concrete properties and also to discover the optimum amount of fly ash as partially cement substitution in increasing mechanical properties of Self-Consolidation concrete. To coop with the problem three different mix design of Self-Consolidation concrete specimens were prepared to accomplish the laboratory experimental program. The mix proportion variation of fly ash replacement is 0%, 15% and 35% from cement weight. The specimens were prepared to test the properties of Self-Consolidation concrete, i.e.: slump flow test, flexural strength test, compressive strength test, and modulus of elasticity. Except slump flow test that was conducted for fresh concrete, the other tests were conducted after 28 days of curing time. After finishing testing programs, it is found that the utilization 15% of fly ash in production of Self-Consolidation concrete improve flexural strength of concrete whereas only a slightly decrease in compressive strength was found.
