Fair-faced concrete and production process thereof
The invention relates to bare concrete and a production process thereof. The bare concrete comprises the following raw materials in parts by weight: 416-436 parts of cement; 37 to 57 parts of mineral powder; 726 to 746 parts of machine-made sand; 966 to 986 parts of broken stone; 165 to 185 parts of water; 9.88 to 11.88 parts of a water reducing agent; 10 to 15 parts of polyvinylidene chloride fiber; 20-30 parts of a dense filler; 5-10 parts of an organic silicon resin emulsion; 3 to 5 parts of hydroxypropyl cyclodextrin; and 1-3 parts of methyl cellulose. The production process comprises the following steps: S1, uniformly mixing the organic silicon resin emulsion, the hydroxypropyl cyclodextrin, the methyl cellulose and the dense filler to obtain a dense mixture; s2, uniformly mixing cement, mineral powder, a water reducing agent and water to obtain cement slurry; s3, uniformly mixing the machine-made sand, the gravels, the dense mixture, the polyvinylidene chloride fibers and the cement slurry to obtain the concrete mixture. The method has the effect of improving the impermeability of the fair-faced concrete.
本申请涉及一种清水混凝土及其生产工艺，清水混凝土原料包括以下重量份的组分：水泥416‑436份；矿粉37‑57份；机制砂726‑746份；碎石966‑986份；水165‑185份；减水剂9.88‑11.88份；聚偏氯乙烯纤维10‑15份；密实填料20‑30份；有机硅树脂乳液5‑10份；羟丙基环糊精3‑5份；甲基纤维素1‑3份。生产工艺为：S1，将有机硅树脂乳液、羟丙基环糊精、甲基纤维素和密实填料混合均匀，得密实拌合料；S2，将水泥、矿粉、减水剂和水混合均匀，得水泥浆液；S3，将机制砂、碎石、密实拌合料和聚偏氯乙烯纤维和水泥浆液混合均匀，得混凝土拌合料。本申请具有提升清水混凝土抗渗性的效果。
