Preparation method of high-performance concrete containing superfine sand
The invention discloses a preparation method of high-performance concrete containing superfine sand, and belongs to the technical field of substance purification processing. Comprising the following steps: step S1, preparing the following raw materials in parts by weight: 50 to 65 parts of Portland cement, 68 to 90 parts of fine aggregate, 150 to 200 parts of coarse aggregate, 9 to 13 parts of active admixture, 0.6 to 0.7 part of water reducing agent, 0.1 to 0.3 part of defoaming agent, 0.06 to 0.3 part of coagulant, 12.5 to 18.5 parts of damping emulsion, 15 to 25 parts of anti-shrinkage reinforcing component and 0.08 to 0.4 part of retarder; s2, preparing concrete; the shrinkage-resistant reinforced component and the damping emulsion are added, the shrinkage-resistant reinforced component contains a carbon nanofiber structure, a quinoline ring, a benzene ring and a cellulose structure, the damping emulsion is prepared by compounding hydrophobic silane modified silicon dioxide and styrene-acrylic emulsion, and through the combined action of the hydrophobic silane modified silicon dioxide and the styrene-acrylic emulsion, the shrinkage resistance, durability and damping performance of the concrete are improved.
本发明公开了一种含特细砂的高性能混凝土制备方法，属于物质纯化加工技术领域，包括以下步骤：步骤S1、准备以下重量份原料：硅酸盐水泥50‑65份、细集料68‑90份、粗骨料150‑200份、活性掺合料9‑13份、减水剂0.6‑0.7份、消泡剂0.1‑0.3份、促凝剂0.06‑0.3份、阻尼乳液12.5‑18.5份、抗缩增强组分15‑25份和缓凝剂0.08‑0.4份；步骤S2、混凝土制备；本发明加入了抗缩增强组分和阻尼乳液，抗缩增强组分中含有纳米碳纤维结构、喹啉环、苯环和纤维素结构，阻尼乳液由疏水硅烷改性的二氧化硅和苯丙乳液复配制得，通过它们的共同作用，提高了混凝土的抗收缩性、耐久性和阻尼性能。
