Impermeable concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses impervious concrete and a preparation method thereof. The impervious concrete is prepared from the following raw materials in parts by weight: 10 to 13 parts of bentonite, 15 to 20 parts of fly ash, 0.05 to 0.08 part of air entraining agent, 10 to 15 parts of Portland cement, 6 to 10 parts of natural river sand, 8 to 10 parts of modified basalt fiber, 0.5 to 0.7 part of thickening agent and 30 to 40 parts of mixing water, wherein the modified basalt fiber is polyacrylamide modified basalt fiber; the preparation method comprises the following steps: heating the mixing water to 60-70 DEG C, adding the weighed fly ash, bentonite, Portland cement, natural river sand and modified basalt fiber, uniformly stirring, sequentially adding the air entraining agent and the thickening agent, continuously stirring, pouring into a mold, carrying out vibration molding, demolding, and curing. The composition disclosed by the invention can be used for structural parts which are in contact with pressure water all the year round, and has the advantages of good impermeability and durability.
本申请涉及建筑材料技术领域，具体公开了一种抗渗混凝土及其制备方法。一种抗渗混凝土包括如下重量份原料：膨润土10‑13份、粉煤灰15‑20份、引气剂0.05‑0.08份、硅酸盐水泥10‑15份、天然河砂6‑10份、改性玄武岩纤维8‑10份、增稠剂0.5‑0.7份、拌合水30‑40份，所述改性玄武岩纤维为聚丙烯酰胺改性玄武岩纤维；其制备方法为：将拌合水加热到60‑70℃后加入称量好的粉煤灰、膨润土、硅酸盐水泥、天然河砂与改性玄武岩纤维搅拌均匀，然后依次加入引气剂与增稠剂继续搅拌，浇筑到模具后振动成型，脱模养护后得到。本申请的组合物可用于常年与压力水接触的结构部位，其具有抗渗性、耐久性好的优点。
