Basalt fiber reinforced reactive powder concrete cover plate and preparation method thereof
The invention discloses a basalt fiber reinforced reactive powder concrete cover plate and a preparation method thereof. The concrete comprises the following components in parts by weight: 50-200 parts of Portland cement, 200-800 parts of quartz sand, 20-50 parts of fly ash, 50-200 parts of mineral powder, 5-90 parts of steel fibers, 5-40 parts of basalt fibers and 1-5 parts of a polycarboxylic acid water reducer. The basalt fiber is selected as a reinforcing material and replaces part of steel fiber in the RPC concrete, the basalt fiber and the steel fiber cooperate to improve the durability of the RPC cover plate concrete, the durability and freeze-thaw resistance of the RPC active concrete are improved, the service life of the RPC concrete is prolonged, and the service life of the RPC active concrete is prolonged. And the RPC performance reduction caused by steel fiber corrosion is avoided. Basalt fibers are easily dispersed in concrete and mortar after being mixed with cement, so that the basalt fiber reinforced concrete has the effects of reinforcement, crack prevention and crack resistance. And the basalt fiber is stretched and formed at a high temperature, and has good ductility and corrosion resistance.
本发明公开了一种玄武岩纤维增强活性粉末混凝土盖板及其制备方法。以重量计，包括以下组分：50‑200份的硅酸盐水泥，200‑800份的石英砂，20‑50份的粉煤灰，50‑200份的矿粉，5‑90份的钢纤维，5‑40份的玄武岩纤维，1‑5份的聚羧酸减水剂。本发明选取玄武岩纤维作为增强材料，在RPC混凝土中替代一部分钢纤维，玄武岩纤维与钢纤维协同提高了RPC盖板混凝土的耐久性能，提高了RPC活性混凝土的耐久性能以及抗冻融性能，有利于延长RPC混凝土的使用寿命，避免因钢纤维腐蚀导致的RPC性能下降。玄武岩纤维与水泥混合容易分散在混凝土和砂浆中，因此玄武岩纤维增强混凝土起到加固作用、防裂、阻裂的作用。且玄武岩纤维在高温下拉伸成型，具备良好的延展性和耐腐蚀性。
