- Abstract
A kind of desert sand steel-PVA fiber high performance concrete is researched. The high performance concrete is composed of water, cement, fly ash and sand. Desert sand instead of part of the river sand, the replacement rate of 30%; fly ash instead of part of the cement, the replacement rate of 15%. The water-binder ratio is 0.19. The content of the steel fiber is 1.2% of the volume of the concrete, and the PVA fiber content is 0.8% of the volume of the concrete, based on the total volume of water, cement, fly ash and sand. The effect of desert sand on the properties of the specimens is obtained by comparing the properties of the specimens with desert sand and the properties of the specimens without sand. The desert sand replacement rate of 30% can increase the compressive strength and the splitting tensile strength, accompanied by a small degree of loss of bending strength. The desert sand steel-PVA fiber high performance concrete presented by this experiment does not contain coarse aggregate, and the properties meet design requirements of the concrete structure. This high performance concrete has the advantages of light weight, environmental protection, and good ductility.
