תקציר

The paper deals with results of experimental research on cement glue mortars containing non-milled fly ash and organic-mineral modifiers are given. The organic-mineral modifiers (OMM) include finely dispersed additives like microsilica or milled fly ash and organic substances (naphthalene formaldehyde superplasticizers and redispersed polymers). Glue cement mortars, modified by OMM additives allow reducing Portland cement consumption, stabilizing and improving the mortars' properties, especially their adhesive and cohesive strength. The influence of the modifier compositions on the strength parameters of mortars for masonry stone walls, facing by ceramic tiles or gluing heat isolation materials was studied. The experimental results show that as the silica additives dispersion is higher the positive effect on adhesive and cohesive strength increases. Optimal content of modifiers in mortars is obtained.
