High Strength Concrete Orthogonal Test of Employing Twin Admixture Technique of Grade II Fly Ash and S95 GGBS

Abstract:

This paper focuses on experimental investigation to produce high strength concrete by employing twin admixture technique of grade II fly ash and S95 GGBS. Different regions have different characteristic of the material, so the strength of high strength concrete would be influenced. At present most of the domestic studies about high strength concrete use the first class powered coal ash and rarely grade II fly. In this study, grade II fly ash is chosen. The dosage of grade II fly ash, S95 GGBS and the water reducing agent are given as the influencing factors of high-strength concretes compressive strength and collapsed slump, and determined the optimum mix amount of the components. The data of strength about the age of 3 day, 7 day and 28 day are analyzed. The results are showed the optimum content of grade II fly ash is between 15% and 20%, S95 GGBS is 15% and water reducing agent is 2%.
