一种高强度混凝土
摘要：
本发明涉及一种高强度混凝土的制备方法，按重量计使用以下重量份的原料制成：水泥350‑380份、水200‑250份、黄砂600‑800份、减水剂12‑15份、石680‑750份，本发明提供的高强度混凝土中使用大量的废旧混凝土回收料作为粗骨料，废旧混凝土的再生方法简单，可以将废旧混凝土中的石块进行分离回收，并可以再次用于混凝土的制备，可以减少混凝土制备时新石块的使用量，减少混凝土的成本。
摘要（英）：

The invention relates to a making method of high-strength concrete. The high-strength concrete is prepared from the following raw materials in parts by weight: 350-380 parts of cement, 200-250 parts of water, 600-800 parts of yellow sand, 12-15 parts of a water reduction agent and 680-750 parts of stone. A great amount of a waste concrete recycling material is used as coarse aggregate in the high-strength concrete provided by the invention, the regeneration method of waste concrete is simple, stone blocks in the waste concrete can be separated and recycled and can be reused in preparation of the concrete, then the amount of new stone can be reduced when the concrete is made, and the cost of the concrete can be reduced.
