Polymer modified factory-made dry mortars as modern building materials

Abstract

Nowadays modified formulated dry-mix mortars have become inseparable part of the modern building technologies and practice. Currently development in the construction materials industry concerns the use of additives and polymeric binders in order to improve technical properties of mortars, mainly cement-based ones. It is not possible to meet today's technical demands for modern cementitious adhesives and grouts for tiles without using redispersible emulsion powders and cellulose ethers as additives. This paper gives an introduction into the application of redispersible emulsion powders and cellulose ethers in ceramic tiles adhesives and grouts as well as requirements and test methods for ceramic tiles adhesives and grouts specified in Poland. In the paper requirements for ceramic tiles adhesives and grouts specified in the Polish National Standards PN-EN 12004 and PN-EN 13888 have been presented.
