Tunnel corrosion-resistant concrete and method for determining mix proportion thereof
The invention belongs to the technical field of concrete formula determination, and particularly relates to tunnel corrosion-resistant concrete and a method for determining the mix proportion of the tunnel corrosion-resistant concrete. The determination method comprises the following steps: determining the type of the preservative based on corrosive ions in underground water of a tunnel face and the concentration thereof; based on an accelerated corrosion test method and the formula and preparation strength of the concrete, obtaining a function relationship among the compressive strength of the corrosion-resistant concrete, the mixing amount of a preservative and the concentration of anti-corrosion ions; and obtaining the mixing amount of the preservative based on the function relationship between the compressive strength of the corrosion-resistant concrete, the mixing amount of the preservative and the concentration of the corrosion-resistant ions, the configuration strength of the concrete and the concentration of the corrosion-resistant ions in underground water of the tunnel face. According to different concentrations of corrosive ions in underground water of different tunnel supporting surfaces, the types and mixing amounts of the preservatives giving consideration to the anti-corrosion effect, the production cost and environmental protection are determined, and different corrosion-resistant concrete mix proportions are determined according to different tunnels.
本发明属于混凝土配方确定技术领域，特别涉及一种隧道耐腐蚀混凝土及其配合比的确定方法。所述确定方法包括基于隧道掌子面地下水中腐蚀性离子及其浓度，确定防腐剂种类；基于加速腐蚀试验法、混凝土的配方和配置强度，得耐腐蚀混凝土抗压强度与防腐剂掺量、防腐蚀离子浓度的函数关系；基于耐腐蚀混凝土抗压强度与防腐剂掺量、防腐蚀离子浓度的函数关系，混凝土的配置强度和隧道掌子面地下水中防腐蚀离子浓度，得防腐剂的掺量。本发明针对不同隧道支撑面地下水中腐蚀性离子浓度的不同，确定兼顾防腐蚀效果、生产成本和环境环保的防腐剂种类以及其掺量，实现根据不同隧道，确定不同的耐腐蚀混凝土配合比。
