A STUDY ON OPTIONAL DESIGN OF EARLY-STRENGTH CEMENT CONCRETE FOR PAVEMENTS

Z Wang, Seunggun Yu

Open publisher page 1 citations

Abstract

This paper focuses on optimal concrete mix design, including the determination of w/c ratio (water over cement in quantity), amount of admixtures, and grading of course aggregate for the cement concrete. Through this research, a special methodology for the concrete mix design was developed, which is capable of adapting to changeable temperature, environment and climate, surface characters of the course aggregate, and concrete curing time for pavements. In addition, this paper presents new ideas in the design of concrete containing admixtures and in the study of surface characteristics of the coarse aggregate. The method is also applicable to the design of ordinary Portland cement concrete.
