Properties of alkali activated self-compacting concrete containing of cement kiln dust.

The idea of the research revolves around the use of by-products of industries (cement kiln dust, fly ash) and their consumption in production of a binder using in manufacture of sustainable concrete with good specifications that exceed the specifications of Portland cement concrete. On the other hand, reducing the manpower, using equipment and tools in casting or compacting of concrete is another factor of sustainability. In this paper, the possibility of using cement kiln dust (CKD) as a percentage of fly ash in the production of alkali activated self-compacting concrete (AASCC) and its effect on the fresh properties, compressive and splitting tensile strength of the resulting concrete was studied., It was observed that the replacement ratios of cement kiln dust CKD instead of fly ash did not affect the workability properties for resulting concrete, where the proportion of (10%) of CKD replacement caused increase in compressive and tensile strengths about 5%, while, (20, 30)% caused decrease in the compressive and splitting tensile strengths about (30, 44)% respectively.
