High-strength concrete and preparation method thereof
The invention belongs to the field of concrete and provides high-strength concrete and a preparation method thereof. The high-strength concrete is prepared from, by weight, 100-200 parts of cement, 50-100 parts of steel slag, 10-20 parts of sintered balls, 30-50 parts of quartz sand, 3-7 parts of sodium diethylenetriamine pentacarboxylate, 2-5 parts of aluminum sulfate binder, 10-15 parts of boron-modified organic silicon resin particles, 7-14 parts of diatomite, 50-80 parts of aggregates, 1-3 parts of a water reducer, 3-4 parts of reinforcing fibers, and 40-80 parts of water. After sodium diethylenetriamine pentacarboxylate is hydrated, a large number of carboxyl groups and hydroxyl groups can be formed, and the polar groups can be adsorbed to the surfaces of cement particles under the action of intermolecular force, so that the strength of concrete can be improved to the maximum extent; meanwhile, under the combined action of the raw materials and the ratio, the strength and the fracture resistance of the concrete are improved, so that cracking in the use process is avoided, and the service life of the concrete is prolonged.
本发明属于混凝土领域，提供了一种高强混凝土及其制备方法，由包括以下重量份的原料制备而成：水泥100～200份，钢渣50～100份，烧结球10～20份，石英砂30～50份，二乙烯三胺五羧酸钠3～7份，硫酸铝结合剂2～5份，硼改性有机硅树脂颗粒10～15份，硅藻土7～14份，骨料50～80份，减水剂1～3份，增强纤维3～4份，水40～80份。本发明的二乙烯三胺五羧酸钠水化后，会形成大量的羧基和羟基，这些极性基团在分子间作用力的作用下会吸附到水泥颗粒表面，从而能够最大限度提高混凝土的强度；同时，在原料及配比的共同作用下，提高了混凝土的强度和抗折性，进而避免使用过程中发生龟裂，提高了混凝土的使用寿命。
