Fly-ash Concrete Pavement

Abstract

Fly-ash Concrete Pavement experiment study is aimed to investigate the physical, chemical and mechanical properties of fly ash cement concrete for road construction. From research, it has been observed that the use of 30% of fly ash and 70% of cement possess a superior performance. Moreover, in construction, the use of fly ash would result in the reduction of the cost of materials and the reduction of greenhouse gas emission. High strength of concrete can be prepared and the incorporation of admixture or substitute to improve the properties of concrete. Test result of specimens indicates the bonding strength of properties, workability, and different reaction when the water ratio a change its content. Slump test having an appropriate workable mixing the slump of a concrete, gave sufficient compressive strength.

Conclusion

In present study physical properties of cement, fly ash, and fine aggregates determined, and then slump test conducted to check concrete workability, and compressive strength test to check its quality and compressive strength. Specific gravity of cement was 3.148 and fly ash 2.27, so specific gravity of fly ash is less than to cement.Standard consistency increased as amount of fly ash increased in cement fly ash mix that means less water quantity need to make cement fly ash mix paste.
