一些化学灰浆由于具有象水一样的粘度而只用于微细裂缝的渗透修补。但是,在灰浆、硅酸盐中最常用的化学物质对于环境来说可能是不安全的。为此,联邦德国已经禁止使用硅酸盐灰浆,因为它会污染地下水。因此,专家们正在研制使用粘度极小的水泥灰浆以代替化学灰浆。法国农泰尔市Soletanche SA公司正在使用一种现场工艺,该工艺可把灰浆中的水泥颗粒从120微米减小到10微米。 Soletanche公司宣称其产品的粘度接近水 Some chemical mortars are only used for the repair of fine cracks by virtue of their water-like viscosity. However, the most commonly used chemicals in mortars and silicates may not be safe for the environment. For this reason, Federal Germany has banned the use of silicate mortars because it pollutes groundwater. Therefore, experts are developing cement pastes with extremely low viscosity to replace chemical mortars. Soletanche SA, a company based in Natur, France, is using an in-situ process that reduces cement particles in mortar from 120 to 10 microns. Soletanche claims its product’s viscosity is close to that of water
