摘要：

The presence of self-compacting concrete (SCC) mix offers many advantages to the structural elements that cast by this type of mix. This paper presents the results on an experimental program carried to explore the possibility of fly ash and alccofine as partial replacement of cement in self-compacting concrete. SCC mixes were designed and cement was replaced with fly ash (i.e. 25%) and alccofine (5, 10 and 15%). Tests were performed to evaluate the compressive strength, split tensile strength and modulus of rupture of SCC. Results indicated that compressive strength, split tensile strength and modulus of rupture of self-compacting concrete improved with incorporation of 25% of fly ash and 10% of alccofine at all the curing ages.
