To Study the Characteristics of Concrete by using High Range Water Reducing Admixture

Super plasticizer admixtures interact chemically with the ingredients of concrete and affects concrete properties in the fresh and hardened state. Theobjectives of this research were to study the effects of super plasticizer admixture on concrete properties such as workability, compressive strength and split tensile strength. A total of five mixes with super plasticizer in proportion of 0%, 0.5%, 1%, 1.5% and 2% by weight of cement for 1:1.5:3 concrete with w/c 0.45. From results it has been concluded that slump is increased with the addition of super plasticizer while strength is increased up to 1% dosage and then decreased gradually. Based on the workresults 2% super plasticizing admixture have shown higher value of workability and 1% super plasticizing has been provided optimum results on strength. Further addition of admixture beyond 1% dosage shown better result on workability, but the strength wasdecreased.”
