Unfired self-compacting concrete and preparation method thereof
The invention discloses a preparation method of unfired self-compacting concrete, wherein the unfired self-compacting concrete comprises the following production raw materials: cement, a mineral admixture, water, polyacrylonitrile-based carbon fibers, a water reducing agent, dolomite coarse aggregate and dolomite fine aggregate, wherein the per-square mixing amount of the dolomite coarse aggregateis 756 to 810 kg, and the per-square mixing amount of the dolomite fine aggregate is 835 to 859 kg. According to the invention, the self-compactness of the unfired concrete material is remarkably improved, and the unfired property of the material is further improved.
本发明公开了一种不发火自密实混凝土的制备方法，生产原料包括水泥，矿物掺合料，水，聚丙烯腈基碳纤维，减水剂，白云石粗集料，白云石细集料；其中，所述白云石粗集料的单方掺量为756～810kg，白云石细集料的单方掺量为835～859kg。其优点是：显著提高不发火混凝土材料的自密实性，并进一步提高材料的不发火性。
