Properties of Concrete Incorporating Low Quantity of Cement and High Volumes of Ground Granulated Slag
This paper presents the results of a study carried out on superplasticized, air-entrained concretes incorporating low quantities of ASTM Type I cement and high volumes of ground granulated blast furnace slag. The properties of fresh concretes including the time of setting were determined and a large number of concrete specimens were subjected to the determination of autogeneous temperature rise, compressive and flexural strengths, Young's modulus of elasticity, drying shrinkage, resistance to chloride ion penetration and sulfate resistance. The details of the study and the results are presented and discussed, particularly with regard to workability, compressive strengths, and flexural strengths.
