| Abstract | ||
| Superplasticizers are considered to be a new class of generic material. They have an efficient capability of increasing the workability without changing the mixture proportions, or reducing the required water content at equal slump. The present study reports results of laboratory experimental works for the evaluation of the given admixture performance on some properties of a plain and a microsilica concrete. In addition, the study shows the effect of both superplasticizer and microsilica in producing a high strength concrete with moderate cement content. The findings indicate that the addition of superplasticizers provides appreciable increase in concrete strength and durability. As well as the ability of production a high strength concrete due to the presence of the mentioned agents combination. | ||
