Low-cost high-strength sprayed concrete and preparation method thereof
The invention discloses low-cost high-strength sprayed concrete and a preparation method thereof, and belongs to the technical field of sprayed concrete production. The invention discloses low-cost high-strength sprayed concrete, which is prepared from the following raw materials in parts by weight: 400 to 600 parts of cement, 100 to 200 parts of coarse aggregate, 50 to 100 parts of admixture, 300 to 600 parts of fine aggregate, 10 to 20 parts of water reducing agent, 10 to 20 parts of accelerator and 250 to 350 parts of water. The concrete disclosed by the invention can solve the problems of low compressive strength, cracks and the like of the traditional concrete, and is produced by adopting a large amount of industrial and agricultural wastes, so that various properties of the concrete are maintained on the basis of greatly reducing the production cost, the construction wastes are effectively treated, and natural resources are saved; the development of green and environment-friendly building materials is deduced.
本发明公开了一种低成本高强度喷射混凝土及其制备方法，属于喷射混凝土生产技术领域。本发明公开的低成本高强度喷射混凝土，包括以下重量份的原料：水泥400‑600份、粗骨料100‑200份、掺合料50‑100份、细骨料300‑600份、减水剂10‑20份、速凝剂10‑20份以及水250‑350份。本发明公开的混凝土可以解决传统混凝土存在的抗压强度低、存在裂缝等问题，并且采用大量的工业和农业废弃物进行生产，在大幅度降低生产成本的基础上保持混凝土的各项性能，有效处理了建筑垃圾，节约自然资源，推断绿色环保型建筑材料的发展。
