In this study super plasticizers admixtures were used for the grades of concrete 15 N/mm2 to improve the properties of fresh and harden concrete in hot weather to achieve these properties in the summer season: • Increase the workability • Increase the compressive strength by adoption super plasticizers admixtures which increase the workability and hence the strength is increased through the reduction of water content. • Reduce the cement content and hence cost saving. The experimental work was divided into two phases: 1. Tests on basic materials (cement, aggregate, sand, water) and the effect of recommended dose of admixture on the properties of fresh and hardened concrete. 2. Concrete testing program for the grade which contain four mixes for each grade. The results of tests for the basic materials were carried to ensure that their results conforming to their standards and can be used. • Ordinary reference mix • Same mix with admixture to increase strength • Same mix with admixture to reduce water content and hence increase strength. • Same mix with admixture to reduce the cement content keeping same workability and strength.
