Title
(EN) CONCRETE WATERPROOFING AGENT
(FR) AGENT IMPERMÉABILISANT POUR BÉTON
(ZH) 一种混凝土防水剂
Abstract
(EN) A concrete waterproofing agent, made of the following raw materials in parts by weight: 1-60 parts of ferric ammonium sulphate; 1-30 parts of glacial acetic acid; 1-40 parts of 8-hydroxquinoline; 1-50 parts of sodium pyrosulphate. The waterproofing and anti-corrosion agent produces a ferric hydroxide colloid at an appropriate time during cement hydration, and the colloid blocks micro-gaps, so as to achieve good waterproofing performance and an ability to resist corrosive media such as chloride ions, sulphate ions and carbon dioxide, in order to significantly increase the service life of concrete.
(FR) L'invention concerne un agent d'imperméabilisation pour béton, constitué des matières premières suivantes en parties en poids : de 1 à 60 parties de sulfate d'ammonium ferrique ; de 1 à 30 parties d'acide acétique glacial ; de 1 à 40 parties de 8-hydroxquinoléine ; de 1 à 50 parties de pyrosulfate de sodium. L'agent d'imperméabilisation et d'anti-corrosion produit un colloïde d'hydroxyde ferrique à un moment approprié pendant l'hydratation du ciment, et le colloïde bloque les micro-espaces, de manière à obtenir une bonne performance d'imperméabilisation et une aptitude à résister à des milieux corrosifs tels que des ions chlorure, des ions sulfate et du dioxyde de carbone, afin d'augmenter significativement la durée de vie du béton.
(ZH) 一种混凝土防水抗侵蚀剂,其由以下重量份的原料制成:硫酸铁铵1-60份;冰醋酸1-30份;8-羟基喹啉1-40份;焦硫酸钠1-50份。该防水抗侵蚀剂能在水泥水化的适当时机产生氢氧化铁胶体,该胶体能在微缝隙处生成并堵塞缝隙,具有良好的防水性能和抵抗氯离子、硫酸根离子、二氧化碳等侵蚀性介质的能力,能大幅提高混凝土的使用寿命。
