Admixture for inhibiting alkali-silicic acid reaction of aggregate and preparation method thereof
The invention discloses an admixture for inhibiting alkali-silicic acid reaction of aggregate, which is prepared from the following components in percentage by mass: 64.1%-76.9% of tuff powder, 9.1%-15.6% of anhydrous lithium bromide, 3.8%-6.1% of carbon fiber and 7.8%-15.4% of calcium carbonate, and the sum of the mass percentages of the components is 100%. The preparation method comprises the following steps: stirring and mixing the tuff powder, the anhydrous lithium bromide and the calcium carbonate according to the proportion, adding the carbon fibers, and stirring again to prepare the admixture for inhibiting the alkali-silicic acid reaction of the aggregate. The method has the characteristic that the alkali-silicic acid reaction of the aggregate can be remarkably inhibited.
本发明公开了抑制骨料碱硅酸反应掺合料，按照质量百分比由以下组分组成：凝灰岩粉64.1％～76.9％，无水溴化锂9.1％～15.6％，碳纤维3.8％～6.1％，碳酸钙7.8％～15.4％，以上各组分的质量百分比总和为100％；本发明还公开了抑制骨料碱硅酸反应掺合料的制备方法，按照比例将凝灰岩粉、无水溴化锂、碳酸钙搅拌混合后加入碳纤维再次搅拌制备出抑制骨料碱硅酸反应掺合料；本发明具有能显著抑制骨料碱硅酸反应的特点。
