Lightweight high-strength low-shrinkage concrete and preparation method thereof
The invention discloses lightweight high-strength low-shrinkage concrete and a preparation method thereof, and belongs to the technical field of building materials. The lightweight high-strength low-shrinkage concrete is prepared from the following components in parts by weight: 480 to 500 parts of cement, 200 to 230 parts of a composite admixture, 40 to 50 parts of glass beads, 250 to 300 parts of quartz sand, 250 to 300 parts of coarse lightweight aggregate, 230 to 260 parts of waste hard plastic particles, 20 to 60 parts of a modifier, 140 to 160 parts of water and 5 to 15 parts of a polycarboxylic acid water reducing agent. The lightweight concrete is prepared by using the glass beads, the coarse lightweight aggregate and the waste hard plastic particles, meanwhile, a high-strength mortar system of the cement, the mineral admixture, the quartz sand and the glass beads is prepared by using a close packing theory, and the lightweight, high-strength and low-shrinkage concrete is prepared by using an optimized construction process.
本发明公开了一种轻质高强低收缩混凝土及其制备方法，属于建筑材料技术领域。其中，轻质高强低收缩混凝土，包括以下重量份数的组分：水泥：480份‑500份，复合掺合料：200份‑230份，玻璃微珠：40份‑50份，石英砂：250份‑300份，粗轻骨料：250份‑300份，废弃硬质塑料颗粒：230份‑260份，改性剂：20份‑60份，水：140份‑160份，聚羧酸减水剂：5份‑15份。通过使用玻璃微珠、粗轻骨料和废弃硬质塑料颗粒来制备轻质混凝土，同时利用紧密堆积理论制备水泥、矿物掺合料、石英砂、玻璃微珠的高强砂浆体系，使用优化后的施工工艺制备得到一种轻质高强低收缩的混凝土。
