Lightweight low-shrinkage high-performance concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses light low-shrinkage high-performance concrete and a preparation method thereof. The lightweight low-shrinkage high-performance concrete is prepared from the following components in parts by weight: 900 to 1100 parts of cement, 320 to 360 parts of lightweight aggregate, 240 to 280 parts of mineral admixture, 3 to 8 parts of conditioning agent, 10 to 15 parts of retarder, 5 to 9 parts of water reducing agent and 300 to 360 parts of water, the lightweight aggregate is formed by mixing ceramsite with the particle size of 2-5mm, ceramsite with the particle size of 8-12mm and expanded perlite with the particle size of 1-3mm; the mineral admixture is formed by mixing slag powder, fly ash and silica fume; the regulator is formed by mixing hydroxyethyl cellulose and biological glue according to the weight ratio of 9: (0.4-1.2). By utilizing the technical scheme provided by the invention, the prepared concrete has the advantages of light weight, low shrinkage, high compressive strength and excellent aging resistance.
本申请涉及建筑材料的技术领域，具体公开了一种轻质低收缩高性能混凝土及其制备方法。本申请公开的轻质低收缩高性能混凝土，包括以下重量份的组分：水泥900‑1100份、轻质骨料320‑360份、矿物掺合料240‑280份、调节剂3‑8份、缓凝剂10‑15份、减水剂5‑9份、水300‑360份；轻质骨料由粒度为2‑5mm的陶粒、粒度为8‑12mm的陶粒、粒度为1‑3mm的膨胀珍珠岩混合而成；矿物掺合料由矿渣粉、粉煤灰、硅灰混合而成；调节剂由重量比为9：0.4‑1.2的羟乙基纤维素和生物胶混合而成。利用本申请提供的技术方案，制备的混凝土具有轻质低收缩的高性能，且抗压强度较高及其耐老化性能优异。
