Sulfate-erosion-resistant concrete admixture, preparation method thereof and concrete
The invention relates to the field of concrete admixtures, in particular to a sulfate-attack-resistant concrete admixture, a preparation method thereof and concrete. The sulfate attack resistant concrete admixture comprises the following components in parts by mass: 90 to 120 parts of barium carbonate, 90 to 120 parts of barium hydroxide, 80 to 100 parts of hydrotalcite, 50 to 100 parts of fly ash and 50 to 100 parts of mineral powder. According to the sulfate-erosion-resistant concrete admixture provided by the invention, the adsorption effect of the admixture on sulfate ions is improved by adding barium carbonate and barium hydroxide, the sulfate-erosion-resistant performance of concrete is remarkably improved, meanwhile, the doping amount of hydrotalcite is relatively small, and the cost of the admixture is greatly reduced; the hydration activity of the fly ash and the mineral powder is improved by utilizing the strong alkalinity of barium hydroxide, so that the influence of the admixture on the mechanical property of the concrete is relatively small.
本发明涉及混凝土外加剂领域，尤其涉及一种抗硫酸盐侵蚀混凝土外加剂及其制备方法和混凝土。所述抗硫酸盐侵蚀混凝土外加剂包括如下质量份数的组分：碳酸钡90～120份，氢氧化钡90～120份，水滑石80～100份，粉煤灰50～100份，矿粉50～100份。本发明提供的抗硫酸盐侵蚀混凝土外加剂通过添加碳酸钡和氢氧化钡提高外加剂对硫酸根离子吸附效果，混凝土抗硫酸盐侵蚀性能得到显著提升，同时水滑石掺量相对较少，外加剂成本大幅降低；利用氢氧化钡的强碱性，提高粉煤灰、矿粉水化活性，使得外加剂对混凝土力学性能影响较小。
