The main objective of this research is to investigate the properties of fresh and hardenedself-compacting concrete (SCC) made from locally available materials in Basrah
governorate-Iraq. The study consists of investigation the influence of volume ratio of
coarse aggregate, limestone powder (LSP) to total powder ratio, and powder/water
ratio. This is to obtain more information which will contribute to a better understanding
to the use of local materials in production of SCC. To achieve these aims, 18 different
mixes (17 SCC mixes and one normal concrete (NC) mix were prepared, tested and
evaluated. It has been noticed that, with the same W/C ratio, SCC mixes prepared with
higher coarse aggregate volume ratio showed higher strengths and modulus of elasticity
than mixes prepared with lower coarse aggregate volume ratio. The increment of LSP
as a replacement of cement leads to lower strengths and static modulus of elasticity.
For the same compressive strength at 28 days, SCC showed 11%, 20% and 26.4%
higher flexural, splitting tensile and bond strengths than NC respectively.
