Sprayed concrete and construction method thereof
The invention relates to sprayed concrete which is composed of a cementing material layer and an interface treatment layer, the cementing material layer is formed by mixing the following components inparts by weight: 200-600 parts of carbon chromium slag, 100-200 parts of magnesium oxide, 100-200 parts of sodium hydrogen phosphate, 50-100 parts of lithium slag powder, 50-100 parts of steel slag powder, 10-50 parts of aluminum powder, 30-60 parts of water glass, 50-180 parts of ASA resin emulsion, 10-50 parts of thickening time control agent, 400-800 parts of recycled aggregate and 100-200 parts of water; the interface treatment layer is formed by mixing the following components in parts by weight: 30-60 parts of acrylic emulsion, 20-40 parts of waterborne polyurethane, 10-30 parts of a silane coupling agent, 5-20 parts of sodium metasilicate, 10-30 parts of limestone powder and 100-200 parts of water. Traditional cement and traditional accelerators are not adopted, environmental protection is facilitated, durability is good, and the rebound rate is low.
本发明涉及一种喷射混凝土，由胶凝材料层和界面处理层组成，所述胶凝材料层由如下重量份的组分混合而成：200～600份碳铬渣，100～200份氧化镁，100～200份磷酸氢钠，50～100份锂渣粉，50～100份钢渣粉，10～50份铝粉，30～60份水玻璃，50～180份ASA树脂乳液，10～50份调凝剂，400～800份再生骨料，100～200份水；界面处理层由如下重量份的组分混合而成：30～60份丙烯酸乳液，20～40份水性聚氨酯，10～30份硅烷偶联剂，5～20份偏硅酸钠，10～30份石灰石粉，100～200份水。本发明没有采用传统水泥以及传统速凝剂，有利于环保，并且耐久性好，回弹率低。
