Engineering properties of sustainable selfcompacting concrete with clay bricks waste aggregate

الملخص EN

The present study covers the use of different percentages (25, 50, 75 and 100%) of clay bricks waste as replacement by volume of coarse natural aggregates to produce sustainable selfcompacted concrete (SCC).

All mixes used containing 10% silica fume as a replacement by cement weight.

The properties of SCC studied were, workability, fresh density, dry density, water absorption, compressive strength, splitting tensile strength, flexural strength, modules of elasticity and thermal conductivity.

The results show that the flow ability, filing ability, and passing ability of self -compacted concrete through steel reinforcement are decrease with the increase of clay brick waste content.

In addition, the segregation resistance decreases with the increase of clay brick waste content of SCC.

The use of clay brick waste aggregate causes reduction in density, compressive strength, splitting tensile strength, flexural strength, modules of elasticity and thermal conductivity of SCC.

The percentage reduction increases with the increase of clay bricks waste content in self-compacted concrete
