AbstractAbout AuthorsReferences
Normative requirements (compression strength and bending strength, adhesion to the masonry) for plastering mortars for finishing of walls made of autoclaved aerated concrete in the EU countries Ukraine, Russia are contradictory and not always substantiated. The plaster mortar is to be considered as a coating connected with masonry through the contact zone. The design of compositions and properties of plaster mortars should be carried out with due regard for stresses occurring in the plastering coating because of its shrinkage and the difference of deformations with masonry as well as deformations of the wall structure and the coating itself. Components of the mix and their number should be selected with due regard for the processes taking place in the course of plaster coating hardening and destruction of the “masonry–plaster coating” system. The result of selecting the composition should ensure the reducing of stresses in the plaster coating and contact zone up to values lesser than the destructive stress.
