Cavern slag stone powder admixture concrete and preparation method thereof
The invention discloses cave slag stone powder admixture concrete and a preparation method thereof. The cave slag stone powder admixture concrete is prepared from the following components in parts by mass: cement, sand, stone, water, a copper slag stone powder admixture, a water reducing agent and an additive, wherein the additive is prepared from calcium oxide, polyacrylamide, wood fiber and boric acid; the preparation method of the cave slag stone powder admixture concrete comprises the following steps: uniformly mixing the components of the concrete; the admixture prepared from calcium oxide, polyacrylamide, wood fiber and boric acid is added into the concrete, on one hand, absorption of the copper slag stone powder to water in the concrete can be inhibited, and on the other hand, the obvious dry shrinkage phenomenon caused by evaporation of water in the hole slag stone powder admixture can be relieved.
本发明公开了一种洞渣石粉掺合料混凝土及其制备方法，一种洞渣石粉掺合料混凝土包括以下质量份数的组分：水泥、砂、石、水、铜渣石粉掺合料、减水剂、外加剂；其中，所述外加剂由氧化钙、聚丙烯酰胺、木质纤维、硼酸制备而成；一种洞渣石粉掺合料混凝土的制备方法包括将混凝土各组分混匀；本申请通过在混凝土中加入由氧化钙、聚丙烯酰胺、木质纤维、硼酸制备而成的外加剂，一方面能够抑制铜渣石粉对混凝土中水分的吸收，另一方面能够缓解由于洞渣石粉掺合料中水分蒸发导致的明显干缩现象。
