Anti-corrosion airtight concrete for gas tunnel secondary lining and preparation method of anti-corrosion airtight concrete
The invention discloses anti-corrosion airtight concrete for a second lining of a gas tunnel. The anti-corrosion airtight concrete comprises a first mixture, a second mixture and quick-setting gel, the first mixture is at least two of the following materials: super absorbent resin and superfine montmorillonite powder; ca (OH) 2 powder and Al2 (SO4) 3 powder; the second mixture comprises cement, water, medium sand, gravel, an auxiliary cementing material and a water reducing agent; the dosage ratio of the first mixture to the second mixture is (1: 500)-(1: 2500). According to the anti-corrosion airtight concrete for the second lining of the gas tunnel and the preparation method of the anti-corrosion airtight concrete, the anti-corrosion airtight concrete for the second lining of the gas tunnel with high airtightness and high corrosion resistance is prepared from the multi-component mineral admixture on the premise that the cement mixing amount and the admixture are not changed.
本发明公开了一种瓦斯隧道二衬用防腐蚀气密性混凝土，包括：第一混合料、第二混合料以及速凝胶；所述第一混合料以下材料中的至少两种：高吸水性树脂、超细蒙脱石粉；Ca(OH)2粉末以及Al2(SO4)3粉末；所述第二混合料包括：水泥、水、中砂、碎石、辅助胶凝材料以及减水剂；所述第一混合料与所述第二混合料的用量比例为1:500～1:2500。本发明提供的一种瓦斯隧道二衬用防腐蚀气密性混凝土及其制备方法，在不更改水泥掺量和外加剂的前提下，通过利用多组分矿物掺合料制备出具有高气密性和高耐腐蚀性的瓦斯隧道二衬用防腐蚀气密性混凝土。
