Concrete containing natural zeolite powder and preparation method thereof
The invention discloses concrete containing natural zeolite powder and a preparation method of the concrete. The concrete comprises the following components in parts by weight: 54-81 parts of light sand, 30-56 parts of lightweight aggregate, 38-60 parts of cement, zeolite powder, a water reducing agent and water, the zeolite powder replaces the cement in an isovolumetric manner in proportion, and the replacement rates are 10%, 20%, 30% or 40% respectively; the mass of the water reducing agent is 0.3% of the total mass; the water cement ratio is 0.3. The light aggregate is selected from natural light aggregate: pumice and volcanic ash; the industrial waste lightweight aggregate comprises expanded slag beads and fly ash pottery ores. According to the invention, the concrete prepared by activating the zeolite powder subjected to water sudden cooling after high-temperature roasting in an acid treatment process can effectively improve the water-retaining property of the concrete, increase the cohesiveness of the concrete, reduce the time loss of the concrete, ensure the good pumpability of the concrete, improve the production efficiency and reduce the production cost. The structure self-weight is effectively reduced, and the structure safety is guaranteed.
本发明公开了一种含天然沸石粉的混凝土及其制备方法，所述混凝土包括如下重量份数的组分：轻砂54～81份、轻骨料30～56份、水泥38～60份、沸石粉、减水剂和水；所述沸石粉按比例等体积代替水泥，替代率分别为10%、20%、30%或者40%；所述减水剂为总体质量的0.3%；水灰比为0.3。所述轻骨料选取天然轻骨料：浮石、火山灰；工业废料轻骨料：膨胀矿渣珠、粉煤灰陶矿。本发明提出通过酸处理工序高温焙烧后水骤然冷却沸石粉进行活化处理后制备出的混凝土能够有效的改善混凝土的保水性、增加混凝土的黏聚性、减少混凝土的经时损失，同时保证混凝土良好可泵送性能，提高生产效率，且有效减轻结构自重，保证结构安全。
