Fabricated aerated concrete plate prepared from concrete recycled aggregate and method
The invention discloses a fabricated aerated concrete plate prepared from concrete recycled aggregate and a method. The fabricated aerated concrete plate is prepared from 300-500 parts of concrete recycled aggregate powder, 100-200 parts of concrete recycled aggregate particles, 200-400 parts of slag powder, 20-60 parts of waste red brick particles, 50-80 parts of an alkali solution, 30-90 parts of a water glass solution, 5-30 parts of aluminum powder, 100-200 parts of a modifier and 100-300 parts of water. The modifier is prepared by mixing 30-50 parts of quick lime, 30-50 parts of zeolite powder, 10-40 parts of magnesium oxide, 1-10 parts of nano titanium oxide, 1-10 parts of sodium hydrogen phosphate and 5-20 parts of sodium carboxymethyl starch according to the steps and then curing to prepare the aerated concrete plate. According to the invention, the problem that alkali-activated aerated concrete is easy to shrink and crack is solved, and the concrete recycled aggregate is utilized.
本发明公开了一种利用混凝土再生骨料制备的装配式加气混凝土板材及方法，由混凝土再生骨料粉300‑500份，混凝土再生骨料颗粒100‑200份，矿渣粉200‑400份，废弃红砖颗粒20‑60份，碱溶液50‑80份、水玻璃溶液30‑90份、铝粉5‑30份，改性剂100‑200份，水100‑300份组成；所述改性剂由生石灰30‑50份，沸石粉30‑50份，氧化镁10‑40份，纳米氧化钛1‑10份，磷酸氢钠1‑10份，羧甲基淀粉钠5‑20份，按步骤混合后养护制成加气混凝土板材。本发明既解决了碱激发加气混凝土易收缩开裂的问题，同时又利用了混凝土再生骨料。
