Concrete slurry and preparation method thereof, and application of concrete and polymer
The invention discloses concrete slurry which comprises the following components in parts by weight: 285 parts of cement, 20-50 parts of fly ash, 613-750 parts of sand, 950-1150 parts of gravel, 85-120 parts of slag powder, 4-15 parts of a polymer, 20-45 parts of an expanding agent and water, wherein the polymer is obtained by carrying out polymerization reaction on raw materials including isopentenol polyoxyethylene ether, acrylic acid and gamma-aminopropyltriethoxysilane; the number-average molecular weight of the isopentenol polyoxyethylene ether is 2100 to 2800, and the molar ratio of the isopentenol polyoxyethylene ether to the acrylic acid to the gamma-aminopropyltriethoxysilane is 1: (3 to 6): (0.05 to 0.5). The concrete slurry is less in hydration heat release and relatively slow in hydration heat release rate.
本发明公开了一种混凝土浆料，包括：水泥285重量份、粉煤灰20～50重量份、砂613～750重量份、碎石950～1150重量份、矿渣粉85～120重量份、聚合物4～15重量份、20～45重量份膨胀剂和水；其中，所述聚合物由包括异戊烯醇聚氧乙烯醚、丙烯酸和γ‑氨丙基三乙氧基硅烷的原料经聚合反应得到；所述异戊烯醇聚氧乙烯醚的数均分子量为2100～2800，所述异戊烯醇聚氧乙烯醚、丙烯酸和γ‑氨丙基三乙氧基硅烷的摩尔比为1:(3～6):(0.05～0.5)。该混凝土浆料水化放热少，水化放热速率较慢。
