The invention provides lightweight concrete. The lightweight concrete is prepared from the following raw material components in percentage by weight: 12 to 30 percent of cement, 15 to 30 percent of quartz powder, 2 to 8 percent of glass beads, 25 to 45 percent of ceramsite, 0.1 to 0.5 percent of graphite, 0.05 to 0.2 percent of a foaming agent, 0.1 to 0.3 percent of a foam stabilizer, 0.1 to 0.3 percent of a cement enhancer, 0 to 1 percent of redispersible latex powder, 0 to 0.2 percent of cellulose ether, 0 to 0.1 percent of a water reducing agent and 6 to 15 percent of water. The lightweight concrete provided by the invention has the advantages of light weight, high strength, low heat conductivity coefficient and the like, is uniform in strength, does not have the phenomena of layering and bubble collapse, and can be widely applied to various building parts with low requirements on strength.
本发明提供了一种轻质混凝土。所述轻质混凝土包括如下重量百分比的原料组分：水泥12‑30％、石英粉15‑30％、玻化微珠2‑8％、陶粒25‑45％、石墨0.1‑0.5％、发泡剂0.05‑0.2％、稳泡剂0.1‑0.3％、水泥增强剂0.1‑0.3％、可再分散乳胶粉0‑1％、纤维素醚0‑0.2％、减水剂0‑0.1％、水6‑15％。本发明提供的轻质混凝土具有重量轻、强度高、导热系数低等优点，且强度均匀，没有分层和塌泡的现象，可以广泛用在对强度要求不高的各类建筑部位。
