Core-shell structure lightweight aggregate and preparation method thereof
The invention discloses a core-shell structure lightweight aggregate and a preparation method thereof, and belongs to the technical field of building materials. The core-shell structure lightweight aggregate comprises a core structure and a shell structure, the core structure is prepared from the following components in parts by weight: 0.10 to 0.20 part of recycled fine aggregate, 0.25 to 0.50 part of phosphogypsum, 0.05 to 0.25 part of mineral powder, 0.04 to 0.10 part of cement, 0.01 to 0.03 part of a foaming agent, 0.03 to 0.05 part of a water reducing agent, 0.02 to 0.04 part of an exciting agent and 0.25 to 0.5 part of water; the shell structure is prepared from the following components in parts by weight: 0.5 to 0.9 part of cement, 0.003 to 0.006 part of a water reducing agent, 0.003 to 0.006 part of a water repellent, 0.005 to 0.015 part of redispersible latex powder and 0.12 to 0.28 part of water. The core-shell structure lightweight aggregate disclosed by the invention has the advantages of high solid waste utilization rate, no need of high-temperature treatment, low water absorption and adjustable cylinder compressive strength and density range, and meanwhile, the prepared concrete does not need to be pre-wetted and is particularly suitable for pumping construction.
本发明公开了一种核壳结构轻骨料及其制备方法，属于建筑材料技术领域。所述核壳结构轻骨料，包括核结构和壳结构；核结构包括如下重量份的组分：再生细骨料0.10‑0.20份、磷石膏0.25‑0.50份、矿粉0.05‑0.25份、水泥0.04‑0.10份、发泡剂0.01‑0.03份、减水剂0.03‑0.05份，激发剂0.02‑0.04份，水0.25‑0.5份；壳结构包括如下重量份的组分：水泥0.5‑0.9份、减水剂0.003‑0.006份、憎水剂0.003‑0.006份、可再分散乳胶粉0.005‑0.015、水0.12‑0.28。本发明的核壳结构轻骨料具有固废利用率高、无需高温处理、吸水率低、筒压强度和密度范围可调控的优点，同时配置出来的混凝土无需预湿、特别适合泵送施工。
