Concrete surface layer reinforcing material and preparation and construction method thereof
The invention discloses a concrete surface layer reinforcing material and a preparation and construction method thereof. The concrete surface layer reinforcing material comprises a component A, a component B and a component C, wherein the component A is prepared from the following components in percentage by weight: 45-50% of organic silicon, 28-30% of epoxy resin, 12-15% of furan resin and the balance of organic solvent; the component B is a mixed aqueous solution of silicate and meta-aluminate; and the component C is an epoxy curing agent. The low-molecular-weight organic silicon material can permeate into concrete capillary channels, and is subjected to hydrolytic condensation reaction under the action of an organic solvent and a silicate alkaline solution (component B) to generate hydrophobic nano silicon dioxide, so that the concrete capillary channels can be fully filled, and the reinforcing effect is achieved; the saltpetering problem of a traditional reinforcing material and the durability problem of an organic silicon resin material can also be solved. The component A, the component B and the component C are constructed in a combined brushing mode, and the reinforcing effect is obvious.
本发明公开了一种混凝土表层增强材料及其制备与施工方法，包括A组分、B组分以及C组分；其中：所述A组分由有机硅45‑50％、环氧树脂28‑30％、呋喃树脂12‑15％和余量的有机溶剂按照重量百分数制备而成；所述B组分为硅酸盐和偏铝酸盐的混合水溶液；所述C组分为环氧固化剂。低分子量有机硅材料可渗透进混凝土毛细孔道内，并在有机溶剂以及硅酸盐碱性溶液(B组分)作用下发生水解缩合反应，生成憎水性纳米二氧化硅，不仅能够充分填充混凝土毛细孔道，达到增强效果，还能解决传统增强材料存在的泛碱问题以及有机硅树脂材料耐久性问题。将A组分、B组分以及C组分通过组合涂刷的方式施工，增强效果明显。
