Reinforcing agent for curing-free pervious concrete as well as preparation method and application of reinforcing agent
The invention relates to the technical field of pervious concrete, in particular to a reinforcing agent for curing-free pervious concrete and a preparation method and application thereof.The reinforcing agent for curing-free pervious concrete is prepared from, by weight, 57.5%-64% of cement hydration accelerant, 35.8%-42% of sulfonated melamine water reducing agent and 0.2%-0.5% of defoaming agent; the cement hydration accelerant is prepared from modified nano hydrated calcium silicate, triethanolamine and diethanolisopropanolamine according to the mass ratio of 10 to (0.5 to 1.3) to (0.1 to 0.5); the modified nano hydrated calcium silicate is silane coupling agent modified nano hydrated calcium silicate or dopamine modified nano hydrated calcium silicate; the reinforcing agent for the curing-free pervious concrete is prepared by matching the cement hydration accelerant with the sulfonated melamine water reducing agent, so that the compressive strength and breaking strength of the curing-free pervious concrete can be effectively promoted, and meanwhile, the water permeability is good, and the freeze-thaw resistance is high.
本发明涉及透水混凝土技术领域，具体涉及一种免养护透水混凝土用增强剂及其制备方法和应用，免养护透水混凝土用增强剂包括以下重量百分比的原料：水泥水化促进剂57.5‑64％、磺化三聚氰胺减水剂35.8‑42％、消泡剂0.2‑0.5％；水泥水化促进剂由改性纳米水化硅酸钙、三乙醇胺、二乙醇单异丙醇胺按质量比10：0.5‑1.3：0.1‑0.5组成；改性纳米水化硅酸钙为硅烷偶联剂改性纳米水化硅酸钙或多巴胺改性纳米水化硅酸钙；本发明将水泥水化促进剂与磺化三聚氰胺减水剂配合制备免养护透水混凝土用增强剂，可有效促进免养护透水混凝土的抗压强度、抗折强度，同时透水性好，抗冻融性强。
