Porous aggregate modified reinforcing agent and preparation method of concrete by use of porous aggregate modified reinforcing agent
The invention discloses a porous aggregate modified reinforcing agent and a preparation method of concrete by use of the porous aggregate modified reinforcing agent, and particularly relates to the porous aggregate modified reinforcing agent, porous aggregate concrete and the preparation method thereof. The porous aggregate modified reinforcing agent is prepared from the following ingredients in parts by weight: 20 to 30 parts of microsphere powder, 10 to 20 parts of nano silicon dioxide, 50 to 60 parts of superfine limestone powder, 1 to 2 parts of redispersible latex powder and 0.05 to 0.01part of hydroxypropyl methyl cellulose. The porous aggregate concrete comprises 30-60 kg of the porous aggregate modified reinforcing agent, 300-400 kg of Portland cement, 80-120 kg of II-grade fly ash, 700-800 kg of corallite, 550-650 kg of coral sand, 190-240 kg of mixing water and 3.0-5.5 kg of a polycarboxylate superplasticizer, and the preparation process comprises the following steps: screening two grades of corallite with the size of 4.75 mm-9.50 mm and the size of 9.50 mm-26.5 mm, mixing the two grades of corallite according to the weight ratio of 3:7, screening the coral sand with thegrain size of less than 4.75mm, weighing the materials , mixing and stirring. According to the invention, workability of coral reef concrete can be effectively improved, bleeding rate of the concreteis reduced, and strength and durability of the concrete are improved.
本发明公开了一种多孔骨料改性增强剂及用于混凝土的制备方法，包括一种多孔骨料改性增强剂和一种多孔骨料混凝土及其制备方法；多孔骨料改性增强剂包括按重量份计的如下配料：20～30份微珠粉、10～20份纳米二氧化硅、50～60份超细石灰石粉、1～2份可再分散乳胶粉、0.05～0.01份羟丙基甲基纤维素；多孔骨料混凝土包括多孔骨料改性增强剂30～60kg，硅酸盐水泥300～400kg，II级粉煤灰80～120kg，珊瑚石700～800kg，珊瑚砂550～650kg，拌合水190～240kg，聚羧酸高效减水剂3.0～5.5kg，其制备过程为：筛选4.75mm～9.50mm、9.50mm～26.5mm两个级配的珊瑚石，按3：7的比例混产、筛选小于4.75mm的珊瑚砂、称取各组分材料，混合搅拌。本发明可以有效改善珊瑚礁混凝土的和易性、降低混凝土的泌水率，提高混凝土的强度和耐久性。
