Lightweight 3D printing concrete and preparation method thereof
The invention discloses lightweight 3D printing concrete and a preparation method thereof. The lightweight 3D printing concrete comprises the following components in parts by mass: 200-300 parts of cement, 50-150 parts of fly ash, 50-100 parts of mineral powder, 130-160 parts of fly ash floating beads with a plurality of particle sizes, 2-4 parts of reinforced fibers, 1-2 parts of a water reducing agent, 0.5-1 part of a water-retaining thickener, 1-10 parts of a rheology modifier and 50-80 parts of water. Multiple experiments prove that the light 3D printing concrete can completely use the fly ash floating beads as the aggregate, the density is 1200-1300kg/m < 3 >, the strength is C30 or above, and meanwhile, the light 3D printing concrete has good 3D printing performance.
本申请公开了一种轻质3D打印混凝土及其制备方法,包括以下质量份数配比的组分:水泥200‑300份、粉煤灰50‑150份、矿粉50‑100份,若干粒径的粉煤灰漂珠130‑160份、增强纤维2‑4份、减水剂1‑2份、保水增稠剂0.5‑1份、流变调节剂1‑10份和水50‑80份。经过多次实验证明,本轻质3D打印混凝土可实现完全使用粉煤灰漂珠作为骨料,实现了密度在1200‑1300kg/m3间,强度在C30以上,同时具有良好的3D打印性能。
