水基渗透型无机防水剂试验应用研究
摘要
建筑工程结构的渗漏是长期以来困扰建筑行业的一个难题,高效防水性能的防水材料研制是科研人员多年来研究的重要课题。而水性渗透型无机防水剂是一种防水性能优越、施工简便、具有再生防水功能的环保型防水材料。本课题依据JC/T 1018-2006《水性渗透型无机防水剂》国家标准进行水性渗透型无机防水剂的配制、性能检测和机理研究。
试验结果表明,水性渗透型无机防水剂的活性物质能够随防水剂渗入到混凝土裂缝中,与混凝土内部的Ca(OH)2和f-CaO直接发生反应,生成不溶于水的枝蔓状结晶体添堵裂缝,阻碍混凝土表面自由水渗入混凝土中,起到防水、防渗漏的作用。活性物质与Ca(OH)2的反应可以减少混凝土中Ca(OH)2的含量,减少Ca(OH)2的溶出,从而提高混凝土的强度和耐久性能。该水性渗透型无机防水剂的外观性能、PH值、密度、凝胶化时间和抗渗性能均达到国家标准。防水剂最佳配合比为:水玻璃70%、%、%、%。

Abstract
The leakage of structural building works has long been a problem in the construction industry, research on waterproof materials with high water resistance has always been an important research subject. Waterbased capillary anic waterproofer is green waterproof material, with superior peformance, simple construction, and recycled water resistance features . The topic based on JC / T 1018-2006 "Waterbased capillary anic waterproofer" national standards to explore the preparation, performance measurement and mechanism of waterbased capillary anic waterproofer.
The results show that the active substances of waterbased capillary anic waterproofer can infiltrate into the concrete cracks, and directly react with Ca(OH)2 and f-CaO which in concrete internal to produce insoluble dendrite-like crystals to block crack, hinder the free water at the surface rating the concrete, play a role as waterproofing, anti-leakaging . Active substances react with Ca(OH)2 can reduce the content and dissolution of Ca(OH)2 in concrete , thereby enhancing the strength and durability of concrete. The appearence properties, PH value, density, gel time and impermeability of waterbased capillary anic waterproofer meet the national standard. Optimum mix for the waterproof: sodium silicate 70%, alum % , sodium citrate %, deionized water % .
Key words: waterbased capillary anic waterproofer, ration, crystallization
