The invention relates to the technical field of concrete, and provides environment-friendly high-strength concrete and a preparation method thereof. The environment-friendly high-strength concrete is prepared from the following components in parts by mass: 30 to 40 parts of cement, 50 to 60 parts of waste concrete, 40 to 50 parts of sand, 30 to 40 parts of pebbles, 10 to 20 parts of silica fume, 3 to 12 parts of 2-[(hydroxymethyl) amino] ethanol modified fibers, 0.5 to 1 part of a water reducing agent, 0.8 to 1.5 parts of a thickening agent and 10 to 20 parts of water. By means of the technical scheme, the problem that in the prior art, concrete prepared from waste concrete is low in strength is solved.
本发明涉及混凝土技术领域，提出了一种环保型高强度混凝土及其制备方法。一种环保型高强度混凝土，包括以下质量份的组分：水泥30~40份、废弃混凝土50~60份、砂40~50份、石子30~40份、硅灰10~20份、2‑[(羟甲基)氨基]乙醇改性纤维3~12份、减水剂0.5~1份、增稠剂0.8~1.5份、水10~20份。通过上述技术方案，解决了现有技术中的废弃混凝土制备出的混凝土强度低的问题。
