Concrete suitable for high-temperature construction environment and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses concrete suitable for a high-temperature construction environment and a preparation method of the concrete. The invention discloses concrete suitable for a high-temperature construction environment. The concrete is prepared from 150 to 200 parts of cement, 60 to 75 parts of fly ash, 60 to 80 parts of mineral powder, 720 to 800 parts of machine-made sand, 980 to 1150 parts of gravel, 10 to 20 parts of manganese slag powder, 3 to 5 parts of ethylene-vinyl acetate copolymer, 8 to 12 parts of additive, 110 to 140 parts of water and 100 to 130 parts of ice blocks, the additive is prepared by dissolving hydroxy propyl cellulose, fatty alcohol-polyoxyethylene ether and sodium allysulfonate in water. The concrete disclosed by the invention not only can keep good working performance and strength development under a high-temperature condition, but also has excellent crack resistance.
本发明涉及混凝土技术领域，具体公开了一种适用于高温施工环境的混凝土及其制备方法。一种适用于高温施工环境的混凝土，包括150~200份水泥、60~75份粉煤灰、60~80份矿粉、720~800份机制砂、980~1150份碎石、10~20份锰渣粉、3~5份乙烯‑醋酸乙烯共聚物、8~12份外加剂、110~140份水、100~130份冰块；外加剂是由羟丙基纤维素、脂肪醇聚氧乙烯醚和烯丙基磺酸钠溶于水后制备而成的。本申请的混凝土不仅能够在高温条件下保持良好的工作性能和强度发展，而且具有优异的抗裂性。
