Self-compacting concrete
The invention relates to self-compacting concrete. The self-compacting concrete comprises the following components in parts by mass: 600-780 parts of gravel; 300 to 390 parts of cement; 70 to 90 parts of fly ash; 700 to 900 parts of aggregate; 120 to 156 parts of water; 80 to 104 parts of mineral powder; 10 to 13 parts of a water reducing agent; 5-7 parts of a defoaming agent; 120 to 140 parts of modified anti-aging rubber; 45 to 60 parts of modified hydrophilic polypropylene fiber; the modified anti-aging rubber raw materials comprise modified anti-oxidation mesoporous silica and styrene butadiene rubber. The modified anti-aging rubber is added into the concrete system, the mechanical property and the anti-aging property of the concrete are improved, and meanwhile, the modified hydrophilic polypropylene fiber is added, so that the effect of further improving the mechanical property of the concrete system can be achieved.
本申请涉及一种自密实混凝土，其包括包括如下质量份的组分：砂石600‑780份；水泥300‑390份；粉煤灰70‑90份；骨料700‑900份；水120‑156份；矿粉80‑104份；减水剂10‑13份；消泡剂5‑7份；改性抗老化橡胶120‑140份；改性亲水聚丙烯纤维45‑60份；改性抗老化橡胶原料包括改性抗氧化介孔二氧化硅、丁苯橡胶。本申请在混凝土体系中添加改性抗老化橡胶，改善了混凝土的力学性能与耐老化性能，同时添加有改性亲水聚丙烯纤维，可进一步提升混凝土体系的力学性能的效果。
