Abstract

Using superfine sand as the main raw material and the superfine sand concrete without coarse aggregate was made by method of semi-dry moulding in this paper. The compressive, splitting tensile and immersion strength of the concrete material was studied to determine the influence of mix proportion of the binding materials. The results show that the optimal mixing ratio for materials used is 70% superfine sand, 15% cement, 9% ground granlated blastfurnace slag( GGBS), 2% gypsum and 4% lime. The compressive, tensile and immersion strength of this concrete at 28 days is 20MPa, 2.5 MPa and 20 MPa respectively, meeting the demand of civil engineering .In areas with an abundance of superfine sand but a shortage of ordinary aggregate, the material mentioned will have prominent economic value as well as promising application prospects.
