Concrete for slip-form process and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses concrete for a slip-form process and a preparation method of the concrete. The concrete for the slip form process is prepared from the following raw materials in parts by weight: 100 to 115 parts of cement, 40 to 55 parts of fly ash, 45 to 50 parts of slag powder, 260 to 320 parts of fine aggregate, 300 to 400 parts of coarse aggregate, 1 to 2.5 parts of water reducing agent, 1.5 to 4 parts of retarder and 75 to 85 parts of water, each part of the retarder is prepared from the following raw materials in parts by weight: 10 to 15 parts of hyperbranched polymer, 3 to 6 parts of organic acid, 2 to 4 parts of zeolite powder and 1 to 3 parts of porous ceramic powder; the hyperbranched polymer contains hydroxyl and/or carboxyl; the organic acid is one or more of tartaric acid, malic acid, citric acid and amino acid. The concrete for the slip-form process has relatively long initial setting time and relatively high compressive strength.
本申请涉及建筑材料技术领域，具体公开了一种用于滑模工艺的混凝土及其制备方法。一种用于滑模工艺的混凝土，由包含以下重量份的原料组成：水泥100‑115份、粉煤灰40‑55份、矿渣粉45‑50份、细骨料260‑320份、粗骨料300‑400份、减水剂1‑2.5份、缓凝剂1.5‑4份、水75‑85份；每份缓凝剂由包含以下重量份的原料组成：超支化聚合物10‑15份、有机酸3‑6份、沸石粉2‑4份、多孔陶瓷粉1‑3份；超支化聚合物中含羟基和/或羧基；有机酸为酒石酸、苹果酸、柠檬酸、氨基酸中的一种或多种。本申请的一种用于滑模工艺的混凝土兼具较长的初凝时间和较高的抗压强度。
