Self-compacting lightweight aggregate machine-made sand concrete and preparation method thereof
The invention discloses self-compacting lightweight aggregate machine-made sand concrete and a preparation method thereof. The self-compacting lightweight aggregate machine-made sand concrete is prepared from the following raw materials in parts by weight: 260 to 300 parts of cement, 120 to 150 parts of fly ash, 80 to 100 parts of admixture, 120 to 150 parts of lightweight aggregate, 360 to 400 parts of machine-made sand, 280 to 330 parts of pottery sand and 10 to 15 parts of water reducing agent. According to the self-compacting lightweight aggregate machine-made sand concrete, the performance of a concrete mixture of the lightweight aggregate can be optimized by pre-wetting the lightweight aggregate, the maximum particle size of the lightweight aggregate is strictly controlled, and the floating phenomenon of the concrete is effectively improved; by adding a composite material in the concrete, the composite material is obtained by magnetically dispersing and compounding the ethylene-vinyl acetate copolymer and the pottery sand according to the mass ratio of 4: 1, and after the composite material is applied to the concrete, the toughness of the concrete can be greatly improved, and the dead weight of the concrete can be greatly reduced.
本发明公开了一种自密实轻骨料机制砂混凝土及其制备方法，包括以下重量份原料：260‑300份水泥、120‑150份粉煤灰、80‑100份掺合料、120‑150份轻骨料、360‑400份机制砂、280‑330份陶砂、10‑15份减水剂。该自密实轻骨料机制砂混凝土，通过对轻骨料进行预湿可以使其混凝土拌合物性能得到优化，严格控制轻骨料最大粒径，使其混凝土上浮现象得到有效改善，通过在混凝土中加入复合料，复合料采用乙烯‑醋酸乙烯共聚物和陶砂按照质量比4:1进行磁力分散复合得到，在复合料进行应用到混凝土中后，可以较大程度上提高混凝土的韧性，并且对于混凝土的自重也能够起到较大程度上的降低。
