Premixed concrete for building and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to premixed concrete for buildings and a preparation method of the premixed concrete. The invention discloses premixed concrete for buildings. The premixed concrete is prepared from the following raw materials in parts by weight: 200 to 300 parts of cement, 600 to 700 parts of machine-made sand, 50 to 60 parts of mineral powder, 40 to 60 parts of fly ash, 900 to 1100 parts of gravel, 120 to 150 parts of natural sand, 50 to 80 parts of modified rubber particles, 6 to 8 parts of water reducing agent and 150 to 170 parts of water, the modified rubber particles are waste rubber tire particles loaded with silicon and phosphorus elements and thioether groups. According to the premixed concrete for the building, the waste rubber tire particles serve as aggregate, waste rubber tires are effectively utilized, meanwhile, the problem of scarcity of building materials is solved to a certain degree, and meanwhile the defects that due to introduction of the rubber particles, the flame retardant property and the anti-aging property of the concrete are poor are effectively overcome through the modifier.
本申请涉及水泥基建筑材料的技术领域，更具体地说，它涉及一种建筑用预拌混凝土及其制备方法。一种建筑用预拌混凝土，包括以下重量份的原料：水泥200‑300份、机制砂600‑700份、矿粉50‑60份、粉煤灰40‑60份、碎石900‑1100份、天然砂120‑150份、改性橡胶颗粒50‑80份、减水剂6‑8份及水150‑170份；所述改性橡胶颗粒为负载有硅磷元素及硫醚基的废旧橡胶轮胎颗粒。本申请的建筑用预拌混凝土将废旧橡胶轮胎颗粒作为骨料，在对废弃橡胶轮胎进行有效利用的同时，还在一定程度上改善建筑材料稀缺的问题，同时通过改性剂有效改善橡胶颗粒引入而产生的混凝土阻燃性能及抗老化性能较差的缺陷。
