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-compacting modified rubber concrete doped with fly ash reaches 270 mm, the expansion degree is 740 mm, and the requirement of the self-compacting concrete for workability is met.
本发明涉及土木工程绿色建筑材料领域，且公开了一种掺粉煤灰的自密实改性橡胶混凝土，包括以下重量配比材料：普通硅酸盐水泥363.61份、粉煤灰158.85份、天然河砂651.24份、改性橡胶粉29.38份、天然碎石1085.4份、城市自来水158.84份、聚羧酸减水剂占硅酸盐水泥和粉煤灰总质量的0.5％。该掺粉煤灰的自密实改性橡胶混凝土及其制备方法，针对橡胶混凝土泵送能力差，工作性低、力学性能低等问题。本发明采用具有火山灰、填充效应的粉煤灰改善了橡胶混凝土的湿堆积密度和水膜厚度，使得橡胶混凝土的工作性得到了显著的改善。本发明提出的掺粉煤灰的自密实改性橡胶混凝土的坍落度达到了270mm，扩展度为740mm，满足了自密实混凝土的对工作性的要求。
