Concrete reinforcing liquid and preparation method thereof
The invention discloses concrete reinforcing liquid and a preparation method thereof, and relates to the field of building materials. The concrete reinforcing liquid is prepared from the following rawmaterials in parts by mass: 4.0 to 4.2 parts of tetraethoxysilane, 0.9 to 1.1 parts of absolute ethyl alcohol, 1.0 to 1.1 parts of saturated oxalic acid solution and 0.1 part of lauryl sodium sulfate. The preparation method comprises the following steps: 1) mixing tetraethoxysilane, absolute ethyl alcohol and a saturated oxalic acid solution in proportion; 2) fully stirring the obtained mixed solution; and 3) adding a surfactant lauryl sodium sulfate, and fully stirring to obtain the concrete reinforcing liquid. The obtained concrete reinforcing liquid is high in infiltration capacity, high in curing speed and good in compatibility with a concrete base material. The invention is beneficial to reinforcement, repair and reinforcement of the concrete base material, has remarkable technical benefits and social benefits, and is convenient to popularize and apply in existing concrete structure repair and reinforcement engineering.
一种混凝土补强液及其制备方法,涉及建筑材料领域。所述混凝土补强液按质量比的原料组成为：正硅酸乙酯4.0～4.2、无水乙醇0.9～1.1、饱和草酸溶液1.0～1.1、十二烷基硫酸钠0.1。制备方法：1)将正硅酸乙酯、无水乙醇、饱和草酸溶液按比例混合；2)将得到的混合溶液充分搅拌；3)加入表面活性剂十二烷基硫酸钠并充分搅拌，即得所述混凝土补强液。所得到的混凝土补强液渗透能力强，固化速度快，与混凝土基材的相容性好。有利于混凝土基材的补强、修复及加固，具有显著的技术效益和社会效益，便于在既有混凝土结构修复加固工程中推广应用。
