This project have been made an trial to study the impact of superplasticezer dosage of 0.5, 0.7, 0.9, 1.1 and 1.2 percentage on execution of set and estimate the optimum ratio of superplasticizer. The experiential tests new and properties hardened of specific for M25 grade are studied and compared the data with concrete ordinary . considerer of the tests in this study , slump test and compressive force test .display the results rise of superplesticizer dosage in set leads to get of better capacity in adding to slump. Furthermore, there is too slightly rise in compressive force than that of concrete ordinary. The experimental results showed a significant increase in the value of compressive strength in comparison with the normal mix. The compressive strength increased about (47.43) percent in comparison with the normal mix. Also, the experimental results showed the optimum ratio of the superplasticizier is (0.7%).
