Method for inhibiting alkali-aggregate reaction of concrete
The invention relates to a method for inhibiting alkali-aggregate reaction of concrete, which comprises the following steps: S1, preparing the following raw materials in parts by weight: 100 parts of cement, 100-300 parts of aggregate, 5-30 parts of nano cellulose and 25-75 parts of water; s2, adding nano cellulose into the water, and mixing at a low speed to obtain a first mixed solution; s3, adding cement into the first mixed solution obtained in S2, and mixing at a medium speed to obtain a second mixed solution; and S4, adding aggregate into the second mixed solution obtained in S3, and mixing at a variable speed to obtain the concrete for inhibiting alkali-aggregate reaction. By inhibiting the alkali-silicic acid reaction of the concrete, the hydration degree and the compactness degree are improved, the expansion rate of cement mortar is reduced, and the purpose of inhibiting the alkali-aggregate reaction of the concrete is achieved.
本发明涉及一种抑制混凝土碱‑骨料反应的方法，其包括以下步骤，S1准备原料，水泥100份，骨料100~300份，纳米纤维素5~30份，水25~75份；S2在所述水中投入纳米纤维素并低速混合，得到第一混合液；S3在所述S2得到的第一混合液中投入水泥并中速混合，得到第二混合液；S4在所述S3得到的第二混合液中投入骨料并变速混合，得到抑制碱‑骨料反应的混凝土。本发明通过抑制混凝土碱硅酸反应，提高水化程度和致密程度，降低水泥砂浆的膨胀率，达到了抑制混凝土碱‑骨料反应的目的。
