Interface agent for reducing springback rate of sprayed concrete and construction method
The invention discloses an interface agent for reducing the rebound rate of sprayed concrete, and the interface agent comprises the following raw materials: 20-30 parts of sandstone, 30 parts of an accelerator, 20-30 parts of mineral powder, 20-25 parts of aluminate, 5-15 parts of a water reducing agent, 3-5 parts of a defoaming agent and water, and the interface agent is prepared from the following raw materials in parts by weight: 20-30 parts of sandstone, 30 parts of an accelerator, 20-30 parts of mineral powder, 20-25 parts of aluminate, 5-15 parts of a water reducing agent, 3-5 parts of a defoaming agent and the balance of water. According to the interface agent for reducing the springback rate of the sprayed concrete and the construction method, the springback rate of the sprayed concrete can be effectively reduced during use, the cost is saved, the concrete is easily bonded with the interface agent in the later period, the overall strength is high, and the anti-seepage and waterproof performance is greatly improved.
本发明公开了一种降低喷射混凝土回弹率的界面剂，包括如下原料，砂石、速凝剂、矿粉、铝酸盐、减水剂和消泡剂，其中砂石20‑30份，速凝剂30份，矿粉20‑30份，铝酸盐20‑25份，减水剂5‑15份，消泡剂3‑5份，水；该降低喷射混凝土回弹率的界面剂及施工方法在使用时能够有效降低喷射混凝土的回弹率，节省成本，且后期混凝土容易与界面剂粘结，整体强度大，已成程度上增大了防渗、防水性能。
