High-strength impervious anti-freezing concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-strength impervious anti-freezing concrete and a preparation method thereof. The high-strength impervious anti-freezing concrete is prepared from the following raw materials in parts by weight: cement, gravel, medium sand, fly ash, silica fume, an additive, water, filling fibers and a coating material, the coating material is prepared by coating propolis particles with paraffin; the preparation method comprises the following steps: weighing the gravel and the medium sand, and uniformly mixing to obtain a primary mixture; weighing coal ash and silica fume, and uniformly mixing to obtain mixed powder; weighing the primary mixture, adding the primary mixture into cement, uniformly mixing, adding the mixed powder, continuously uniformly mixing, adding filling fibers and a coating material, and uniformly mixing to obtain a mixture; weighing an additive and water, adding the additive and the water into the mixture, uniformly mixing to obtain a mixed material, and pouring, curing and demolding the mixed material to obtain a finished product of concrete; meanwhile, the concrete has the advantages of high strength, permeability resistance and freezing resistance.
本申请涉及混凝土领域，具体公开了一种高强抗渗抗冻混凝土及其制备方法；一种高强抗渗抗冻混凝土，由包含以下重量份的原料制成：水泥、碎石、中砂、粉煤灰、硅灰、外加剂、水、填充纤维、包膜料；包膜料由石蜡包覆蜂胶颗粒制备而成；其制备方法为：称取碎石、中砂混合均匀制得初混料；称取粉煤灰、硅灰混合均匀制得混粉料；称取初混料添加到水泥中混合均匀，然后添加混粉料继续混合均匀，再添加填充纤维、包膜料混合均匀，制得混合料；称取外加剂、水添加到混合料中混合均匀，制得拌和料，拌和料经浇筑、养护、脱模，制得成品混凝土；同时具有高强、抗渗、抗冻的优点。
