Interactions between cellulose ethers and cements with several main constituents in a model mix formulation for tile adhesives

The interactions between (un)modified methyl hydroxyethyl celluloses and cements with several main constituents were determined using a model mix formulation for tile adhesives. The results show that these clinker-efficient cements with reduced specific CO2 emissions can also be used in complex mortar formulations and in this way increase the sustainability.

1 Introduction

Cements with further main constituents in addition to clinker have already been in use for a long time for concretes and also for plastering and masonry mortars because of their ecological, economic and technical advantages. However, formulations such as tile adhesives, which dominate in the field of premixed dry mortar, still primarily contain Portland cement. This is due to the lack of knowledge concerning the interactions between further cement main constituents additional to clinker and the admixtures that are required for such formulations. These admixtures are mainly water...
