High-durability concrete and preparation method thereof
The invention provides high-durability concrete and a preparation method thereof, and belongs to the technical field of concrete. The concrete comprises the following components in parts by weight: 100-200 parts of cement, 15-35 parts of fly ash, 30-80 parts of nano microspheres, 20-30 parts of mineral powder, 10-18 parts of aluminum oxide, 150-350 parts of sand, 20-30 parts of plastic fibers, 300-600 parts of gravels, 10-15 parts of natural zeolite ultrafine powder, 3-9 parts of sodium sulfate, 5-15 parts of diethanol amine, 4-10 parts of polypropylene fibers, 10-17 parts of a water reducingagent and 50-120 parts of water. By adding diethanol amine, fly ash and polypropylene fiber, the early strength of the concrete is improved, the strength, corrosion resistance, chloride ion penetration resistance, carbonization resistance and impermeability of the concrete are effectively improved, and the concrete has high durability, can be widely used in tall buildings, highways and dams, and has long overall service life.
本发明提供了一种高耐久性混凝土及其制备方法，属于混凝土技术领域。包括以下重量份数的组分：水泥100～200份，粉煤灰15～35份，纳米微珠30～80份，矿粉20～30份，氧化铝10～18份，砂150～350份，塑料纤维20～30份，碎石300～600份、天然沸石超细粉10～15份、硫酸钠3～9份、二乙醇胺5～15份，聚丙烯纤维4～10份、减水剂10～17份和水50～120份。本发明通过加入二乙醇胺、粉煤灰和聚丙烯纤维，提高了混凝土的早期强度，有效提高了混凝土的强度、抗腐蚀性性能、抗氯离子渗透性能、抗碳化性能和抗渗性能，耐久性高，在高楼、公路和大坝可以广泛使用，且整体使用寿命较长。
