Ultra-high performance concrete and preparation method thereof
The invention relates to the technical field of concrete, and provides ultra-high performance concrete. The ultra-high performance concrete is prepared from the following ingredients in parts by weight: 800 to 1000 parts of cement, 300 to 350 parts of silica fume, 100 to 200 parts of composite fibers, 150 to 200 parts of ground quartz sand, 10 to 15 parts of a polycarboxylic acid water reducing agent, 1 to 3 parts of sodium 2,3-bis(tetradecanamide)propyl-2-trimethylammonioethyl phosphate, 3 to 5 parts of tetramethyl tetraphenyl tripolysiloxane and 150 to 200 parts of water. Through the above technical scheme, the problem that fluidity is not matched with strength and toughness in the prior art is solved.
本发明涉及混凝土技术领域，提出了一种超高性能混凝土，按照重量份包括以下组分：水泥800～1000份、硅灰300～350份、复合纤维100～200份、磨细石英砂150～200份、聚羧酸类减水剂10～15份、2,3‑二(十四碳酰氨基)丙基2‑三甲基铵乙基磷酸酯钠1～3份、四甲基四苯基三聚硅氧烷3～5份、水150～200份。通过上述技术方案，解决了现有技术中流动性和强度韧性不匹配的问题。
