Self-compacting modified rubber concrete doped with fly ash and preparation method of self-compacting modified rubber concrete

The invention relates to the field of green building materials in civil engineering, and discloses self-compacting modified rubber concrete doped with fly ash. Comprising the following materials in parts by weight: 363.61 parts of ordinary Portland cement, 158.85 parts of fly ash, 651.24 parts of natural river sand, 29.38 parts of modified rubber powder, 1085.4 parts of natural gravel, 158.84 parts of urban tap water, and a polycarboxylic acid water reducer accounting for 0.5% of the total mass of the Portland cement and the fly ash. The self-compacting modified rubber concrete doped with fly ash and the preparation method thereof aim at solving the problems that rubber concrete is poor in pumping capacity, low in workability, low in mechanical property and the like. The wet stacking density and the water film thickness of the rubber concrete are improved by adopting the coal ash with volcanic ash and filling effects, so that the workability of the rubber concrete is remarkably improved. The slump of the self
