Sulfate corrosion resistant concrete
The invention discloses sulfate corrosion resistant concrete which is characterized by comprising the following components in parts by mass: 150-200 parts of water, 400-500 parts of a gel material, 700-750 parts of fine aggregate, 1000-1100 parts of graded coarse aggregate, 3-5 parts of a water reducing agent and 1-3 parts of an air entraining agent, the water-binder ratio of the concrete is 0.2-0.5, the sand ratio is 30-50%, and the designed slump is 150-200 mm. The sulfate corrosion resistant concrete for the gypsum layer surrounding rock tunnel is obtained by strictly controlling the quality of the raw materials and screening a large number of tests, and can meet the standard of concrete construction in the gypsum layer surrounding rock tunnel; according to the concrete, through interaction of various raw materials, the prepared finished product can resist erosion of sulfate ions, the durability of the concrete is improved, the service life of the concrete is prolonged, and the concrete has good social benefits and is particularly suitable for constructional engineering with high-concentration sulfate surrounding rocks.
本发明公开了一种抗硫酸盐腐蚀的混凝土，其特征在于，按质量比计，包括水150～200份，凝胶材料400～500份、细骨料700～750份、级配粗骨料1000～1100份，减水剂3～5份、引气剂1～3份，所述混凝土的水胶比为0.2～0.5、砂率为30～50％、设计坍落度为150mm～200mm。本发明通过对各组分原材料进行严格的质量控制和大量试验筛选，得到了一种针对石膏层围岩隧洞使用的抗硫酸盐腐蚀的混凝土，其能够满足在石膏层围岩隧洞进行混凝土施工的标准；混凝土通过各种原料的相互作用，制备的成品可以抵御硫酸根离子的侵蚀，增加了混凝土的耐久性，延长了混凝土的使用年限，具有良好的社会效益，特别适用于具有高浓度硫酸盐围岩的建筑工程使用。
