Research on Performance Concrete Made with Slay-Fly Ash and Ground Limestone

Abstract:

Base on experimental studying, early strength and work performance of portland cement, slay cement and fly ash cement improves and enhances when added ground limestone into and the adding content is beyond 8% .The strength of concrete is better than ordinary concrete, early strength increases by 16.9% when added ground limestone into and the adding content is beyond 10%. By studying on experiment, the strength of concrete which has been added slay and fly ash into when added ground limestone into and the adding content is 10% improves more than strength of concrete that has only adds slay or fly ash into. The fluidity of concrete that has added slay and fly ash into when added ground limestone into and the adding content is 10% lose small, this character is good at concrete construction. This experiment provides help for us to select concrete additive admixture and make good use of industrial waste.
