Abstract:energy safly ash of all concre structural Three major factors, namely ings, and inherent technical controlled quality and compo te construction. This paper quality containing fly ash, environment protection, advantages, demand that sition be incorporated shows that concrete of steel fibres, normal in weight or lightweight aggregates and a plasticizing/water-reducing admixture or a superplasticizer can be designed to produce cohesive and workable mixes that enable easy transportation, pumping f compaction and finishing of the material. It is also shown that such mixes can be easily and satisfactorily vibrated into place in structural members with bar reinforcement and thin sections. Mixes designed by partial but direct replacement of 30% by weight of cement can have early strength and elasticity properties comparable to concrete without fly ash, and exhibit structural behaviour similar to normal concrete. Extensive data are presented to demonstrate the applicability of these materials in practice.
