Self-leveling concrete and preparation method thereof
The invention discloses self-leveling concrete which comprises the following components in parts by weight: 15-20 parts of cement, 8-12 parts of superfine slag powder, 40-45 parts of sand, 20-30 partsof gravel, 10-15 parts of a cementing material, 6-10 parts of fly ash, 3-5 parts of slag, 1-3 parts of quartz sand, 0.5-1 part of citric acid, 0.3-0.7 parts of lithium carbonate, 0.3-0.7 parts of a superplasticizer, 0.3-0.7 parts of an air entraining agent and 7-7.5 parts of water. The invention belongs to the field of concrete, and particularly provides self-leveling concrete and a preparation method thereof. Small-fineness fly ash and slag are doped to replace cement, on one hand, the comprehensive performance of concrete and cement products is improved, the strength, seawater erosion performance, compactness, bleeding amount and hydration heat of the concrete are improved, meanwhile, the shearing stress of slurry can be effectively reduced, the fluidity is improved, and on the basis oftraditional concrete, the fluidity of the concrete is improved by increasing the dosage of the cementing material.
本发明公开了一种自流平混凝土，包括下列重量份数的组分：水泥15～20份、矿渣微粉8～12份、砂40～45份、碎石20～30份、胶凝材料10～15份、粉煤灰6～10份、矿渣3～5份、石英砂1～3份、柠檬酸0.5～1份、碳酸锂0.3～0.7份、超塑化剂0.3～0.7份、引气剂0.3～0.7份、水7～7.5份。本发明属于混凝土领域，具体提供了一种自流平混凝土及其制备方法，通过掺加细度小的粉煤灰和矿渣替代水泥用量，一方面改善混凝土和水泥制品的综合性能，提高混凝土的强度、海水侵蚀性能、致密性、泌水量和水化热，同时，可以有效减小浆体的剪切应力，增大流动性，并且在传统的混凝土的基础上通过增加胶凝材料的用量，改善混凝土的流动性。
