High-flow-state low-shrinkage environment-friendly premixed concrete and preparation method thereof
The invention discloses high-flow-state low-shrinkage environment-friendly premixed concrete and a preparation method thereof, belongs to the technical field of premixed concrete, and aims to solve the problems of low flowability, low durability and poor impermeability and frost resistance of the premixed concrete. The high-flow-state low-shrinkage environment-friendly premixed concrete comprises the following raw materials in parts by mass: 25-30 parts of cement; 55 to 65 parts of sand; 100 to 120 parts of broken stone; 5 to 10 parts of a mineral admixture; a concrete admixture; 0.5 to 1.5 parts of the raw materials; and 10 to 18 parts of water. According to the high-flow-state low-shrinkage environment-friendly premixed concrete and the preparation method thereof, the high-flow-state low-shrinkage environment-friendly premixed concrete has better mechanical property and durability, fluidity can be kept for a long time, the pumping height and the pumping distance of the premixed concrete can be effectively increased, slump loss of the concrete can be effectively controlled, the mixing amount is low, the water-reducing rate is high, shrinkage is small, the anti-permeability performance is improved, and the service life of the concrete is prolonged. The durability of the structure is improved, noise pollution is reduced, cement can be saved, and the environment is protected.
本发明公开了一种高流态低收缩环保型预拌混凝土及其制备方法，属于预拌混凝土技术领域，为了解决预拌混凝土的流动性、耐久性低下且抗渗抗冻性能差的问题，包括如下质量份数的原料：水泥：25‑30份；砂子：55‑65份；碎石：100‑120份；矿物掺合料：5‑10份；混凝土外加剂；0.5‑1.5份；水：10‑18份。本发明的高流态低收缩环保型预拌混凝土及其制备方法，具有更好的力学性能和耐久性能，可长时间保持流动性，可有效提高预拌混凝土的泵送高度和泵送距离，可有效控制混凝土的坍落度损失，掺量低，减水率高，收缩小，提高抗渗性能，提高结构物的耐久性，降低了噪音污染，可以节约水泥，保护环境。
