Lightweight composite foam concrete and preparation method thereof
The invention belongs to the technical field of building materials. The invention relates to foam concrete, in particular to light composite foam concrete and a preparation method thereof. The lightweight composite foam concrete is prepared from the following raw materials in parts by weight: 120 to 130 parts of shale ceramsite, 15 to 20 parts of large-particle layered organic bentonite, 12 to 16 parts of small-particle layered organic bentonite, 300 to 320 parts of cement, 30 to 35 parts of foaming agent, 4 to 6 parts of foam stabilizer and 10 to 15 parts of water reducing agent, wherein the water cement ratio of the lightweight composite foam concrete is 0.45 to 0.55; the D50 of the shale ceramsite ranges from 20 mm to 25 mm; the shale ceramsite is porous ceramsite, and the average pore size of the porous ceramsite is 0.6-0.8 mm; the D50 of the large-particle layered organic bentonite ranges from 1.5 mm to 2.0 mm; the D50 of the small particle layered organic bentonite ranges from 0.1 mm to 0.12 mm; the large-particle layered organic bentonite at least partially coats the surface of the shale ceramsite and covers at least part of pores in the surface of the shale ceramsite; the shale ceramsite is at least partially filled with the small-particle layered organic bentonite, and at least partial pores in the shale ceramsite are filled with the small-particle layered organic bentonite.
本发明属于建筑材料技术领域。更具体地，涉及一种轻质复合泡沫混凝土及其制备方法。本发明的产品包括以下重量份数的原料：120‑130份页岩陶粒，15‑20份大颗粒层状有机膨润土，12‑16份小颗粒层状有机膨润土，300‑320份水泥，30‑35份发泡剂，4‑6份稳泡剂，10‑15份减水剂，轻质复合泡沫混凝土的水灰比为0.45‑0.55；页岩陶粒的D50为20‑25mm；页岩陶粒为多孔陶粒，并且，多孔陶粒的平均孔径为0.6‑0.8mm；大颗粒层状有机膨润土的D50为1.5‑2.0mm；小颗粒层状有机膨润土的D50为0.1‑0.12mm；大颗粒层状有机膨润土至少部分包覆于页岩陶粒表面，并覆盖页岩陶粒表面的至少部分孔隙；小颗粒层状有机膨润土至少部分填充于页岩陶粒内部，并填充于页岩陶粒内部的至少部分孔隙。
