Aggregate alkali active inhibiting material and preparation method thereof
The invention discloses an aggregate alkali activity inhibiting material which is prepared from the following components in percentage by mass: 10-20% of modified polyvinyl alcohol fiber, 10-20% of modified polyformaldehyde fiber, 15-30% of basalt fiber, 10-20% of steel fiber and 25-35% of nano metakaolin, and the sum of the mass percentages of the components is 100%. The invention further discloses a preparation method of the aggregate alkali active inhibiting material. The preparation method comprises the following steps: stirring and mixing the modified polyvinyl alcohol fiber, the basalt fiber and the nano metakaolin, adding the modified polyformaldehyde fiber and the steel fiber, and stirring and mixing again; the invention has the characteristics of inhibiting the harm of aggregate alkali activity reaction to concrete and improving the workability and mechanical properties of concrete.
本发明公开了抑制骨料碱活性材料，按照质量百分比由以下组分组成：改性聚乙烯醇纤维10%~20%，改性共聚甲醛纤维10%~20%，玄武岩纤维15%~30%，钢纤维10%~20%，纳米偏高岭土25%~35%，以上各组分质量百分比总和为100%；本发明还公开了抑制骨料碱活性材料的制备方法，将改性聚乙烯醇纤维、玄武岩纤维和纳米偏高岭土搅拌混合后加入改性共聚甲醛纤维和钢纤维再次搅拌混合；本发明具有抑制骨料碱活性反应对混凝土的危害和提高混凝土的工作性及力学性能的特点。
