Underwater low-water-bleeding concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses underwater low-water-bleeding concrete and a preparation method thereof. The underwater low-water-bleeding concrete is prepared from the following components in parts by weight: 370 to 420 parts of cement, 650 to 700 parts of sand, 1060 to 1100 parts of stones, 40 to 55 parts of fly ash, 140 to 190 parts of water, 60 to 80 parts of mineral powder, 5 to 10 parts of a flocculating agent, 10 to 15 parts of a water reducing agent and 18 to 30 parts of an anti-dispersing agent. The anti-dispersing agent comprises an early strength agent, a tackifier and silica fume in a mass ratio of 1: (2-3): (1-2); the tackifier comprises betaine, hexadecyl trimethyl ammonium bromide and 4-tributyl methyl ammonium bromide; the early strength agent comprises potassium bromide, sodium 2,2'-dithiodibenzoate and sodium cinnamate. The underwater low-water-bleeding concrete has the advantages of being small in bleeding rate, high in underwater cohesiveness, not prone to dispersion and capable of effectively preventing algae plants from growing.
本申请涉及建筑材料领域，具体公开了一种水下用低泌水混凝土及其制备方法。水下用低泌水混凝土包括以下重量份的组分：370‑420份水泥、650‑700份砂子、1060‑1100份石子、40‑55份粉煤灰、140‑190份水、60‑80份矿粉、5‑10份絮凝剂、10‑15份减水剂、18‑30份抗分散剂；抗分散剂包括质量比为1:2‑3:1‑2的早强剂、增粘剂和硅灰；增粘剂为包括以下组分：甜菜碱、十六烷基三甲基溴化铵和4‑三丁基甲基溴化铵；早强剂包括以下组分：溴化钾、2,2’‑二硫代二苯甲酸钠、肉桂酸钠。本申请的水下用低泌水混凝土具有泌水率小，水下粘聚性高，不易分散，有效防止藻类植物生长的优点。
