Super-retarding concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses super-retarding concrete and a preparation method thereof. The super-retarding concrete is prepared from the following raw materials in parts by weight: 165 to 175 parts of water, 160 to 260 parts of cement, 983 to 1000 parts of pebbles, 830 to 845 parts of sand, 110 to 160 parts of admixture, 3 to 6 parts of retarder, 2 to 5 parts of preservative and 10 to 20 parts of lubricant, the retarder is prepared from the following raw materials in parts by weight: 150 to 200 parts of wheat straw alkaline solution, 150 to 200 parts of slump retaining agent, 60 to 80 parts of white sugar, 30 to 50 parts of sodium gluconate, 0.05 to 0.08 part of lauryl sodium sulfate and 0.05 to 0.1 part of hydroxypropyl methyl cellulose. The super-retarded concrete has the advantages that the setting time is prolonged, the fluidity of the concrete is good, the compactness is high, and the drying shrinkage rate is small.
本申请涉及建筑材料领域，具体公开了一种超缓凝混凝土及其制备方法。一种超缓凝混凝土，包括以下重量份的原料：165‑175份水、160‑260份水泥、983‑1000份石子、830‑845份砂子、110‑160份掺合料、3‑6份缓凝剂、2‑5份防腐剂、10‑20份润滑剂；所述缓凝剂包括以下重量份的原料：150‑200份麦秸碱溶液、150‑200份保坍剂、60‑80份白糖、30‑50份葡萄糖酸钠、0.05‑0.08份十二烷基硫酸钠、0.05‑0.1份羟丙基甲基纤维素。本申请的超缓凝混凝土具有凝结时间延长，而且混凝土流动性好，密实度高，干燥收缩率小的优点。
