Preparation process of renewable lightweight concrete
The invention discloses a preparation process of renewable lightweight concrete, which comprises the following raw materials in parts: 120-200 parts of water, 100-180 parts of cement, 80-150 parts of sand, 50-80 parts of expanded polystyrene, 50-70 parts of benzene decale fine aggregate, 90-150 parts of recycled aggregate, 10-20 parts of a water reducer, 15-25 parts of an accelerator, 5-15 parts of a binder and 10-25 parts of an air entraining agent. Thecement is particularly Portland cement, the sand is sand with the average particle size of 0.15-2 mm, the water reducer is prepared by mixing hydroxyethyl acrylate, sodium persulfate and allyl polyoxyethylene ether according to the ratio of (3-7): (4-8): (5-9), the accelerator is prepared by mixing sodium aluminate, potassium silicate and quick lime according to the ratio of (4-7): (2-6): (3-6), and the binder is prepared by mixing polyvinyl alcohol, sodium stearate and sodium sulfinate according to the ratio of (1-8): (1-9): (2-7). Traditional aggregate is replaced by waste gas concrete, and then the additive is added, so that the prepared concrete has the advantages of light weight, enhanced strength along with the addition of auxiliary materials, low cost, reasonable matching, convenient use, and convenient popularization and application.
本发明公开了一种可再生轻质混凝土制备工艺，包括以下份数的原材料：水120‑200份、水泥100‑180份、砂80‑150份、膨胀聚苯乙烯50‑80份、苯脱克细骨料50‑70份、再生骨料90‑150份、减水剂10‑20份、速凝剂15‑25份、粘结剂5‑15份、引气剂10‑25份，水泥具体为硅酸盐水泥，砂为平均粒径为0.15‑2mm的砂石，减水剂的配比为3‑7:4‑8:5‑9的丙烯酸羟乙酯、过硫酸钠和烯丙基聚氧乙烯醚混合制得，速凝剂的配比为4‑7:2‑6:3‑6的铝酸钠、硅酸钾和生石灰混合制得，粘结剂的配比为1‑8:1‑9:2‑7的聚乙烯醇、硬脂酸钠和亚磺酸钠混合制得，本发明通过传统的骨料替换成废气的混凝土，再添加添加剂，使得制备出来的混凝土具备重量轻，并随着辅料的添加，还增强了强度并具有成本低的优点，搭配合理，使用方便，便于推广使用。
