USE OF A MIXTURE OF METAL SOAPS, QUARTZ SAND AND ANIONIC SURFACTANTS AS AIR PORP FOR SALTY MORTAR

摘要

The use of a mixture of 20 to 50 parts wt. of a metallic soap and 40 to 80 parts wt. of finely divided quartz sand to which 0.5 to 10 % wt. of an anionic tenside is added as an air pore former for mortars based on salt-containing sand gives the surfaces coated with this mortar high mechanical stability and long useful life despite the salt content.
