Lightweight ultrahigh-strength concrete and preparation method thereof
The invention relates to lightweight ultrahigh-strength concrete and a preparation method thereof. The lightweight ultrahigh-strength concrete comprises, by weight, 630 to 650 parts of cement, 280 to300 parts of ultrafine fly ash, 180 to 200 parts of silica fume, 100 to 120 parts of carborundum powder, 100 to 200 parts of floating beads, 150 to 200 parts of Peek plastic particles, 18 to 23 partsof organic polymer water-absorbent resin and 20 to 30 parts of a polycarboxylate superplasticizer, the water-binder ratio is 0.13 to 0.15, the floating beads are divided into two particle size gradesof 40 to 100 meshes and 20 to 40 meshes. According to the obtained lightweight ultrahigh-strength concrete, the internal structure is fully optimized and improved by the doped powder and aggregate, the volume weight is greatly reduced, the overall strength is improved, the performances are excellent, the preparation is simple, and the lightweight ultrahigh-strength concrete is suitable for popularization.
本发明涉及一种轻质超高强混凝土及其制备方法，该轻质超高强混凝土按重量份数计，包括以下组分：630‑650份水泥，280‑300份超细粉煤灰，180‑200份硅灰，100‑120份金刚砂粉，100‑200份漂珠，150‑200份Peek塑料颗粒，18‑23份有机高分子吸水树脂，20‑30份聚羧酸减水剂，0.13‑0.15水胶比，其中漂珠分为40‑100目和20‑40目两个粒度等级。所得轻质超高强混凝土，其掺入的粉料和集料对内部结构进行充分的优化和改善，在大幅降低容重的同时，提高了整体强度，性能优异，制备简单，适宜推广。
