High-performance artificial sand concrete and preparation method thereof
The high-performance artificial sand concrete is prepared from the following components in parts by weight: 540 to 570 parts of coarse aggregate, 390 to 410 parts of fine aggregate, 80 to 100 parts of mineral admixture, 16 to 28 parts of coarse aggregate admixture, 700 to 760 parts of artificial sand, 330 to 350 parts of cement, 145 to 170 parts of water, 0.1 to 0.5 part of polymerizing agent, 5.5 to 7.5 parts of water reducing agent and 0.03 to 0.06 part of air entraining agent, according to the high-performance artificial sand concrete, the mineral admixture, the coarse aggregate admixture and the artificial sand graded mixture are added to replace natural sand, so that a pouring structure is stable in filling and good in compactness, the detected slump value and the slump amplitude are small, the structural appearance quality of the high-performance artificial sand concrete can be improved, and the service life of the high-performance artificial sand concrete is prolonged. The improved compressive strength ensures the durability of the high-performance artificial sand concrete, and can meet the strength requirements of higher-grade high-performance artificial sand concrete.
本发明公开了一种高性能人工砂混凝土，包括以下重量份数的组分：粗集料540‑570份、细集料390‑410份、矿物参合料80‑100份、粗骨参合料16‑28份、人工砂700‑760份、水泥330‑350份、水145‑170份、聚合剂0.1‑0.5份、减水剂5.5‑7.5份、引气剂0.03‑0.06份；本发明高性能人工砂混凝土中通过加入矿物参合料和粗骨参合料，人工砂级配混合料代替天然砂，使得浇筑结构填充稳定，且致密性较好，检测塌落度数值以及塌落幅度较小，以及可以改善高性能人工砂混凝土的结构外观质量，提升的抗压强度保证了高性能人工砂混凝土的耐久性，可以满足更高级别的高性能人工砂混凝土强度需求。
