Influence of Natural Organic Polymers upon the Mechanical Properties of Plaster Mortars

The present paper shows the influence of polymer additions (casein, rice, egg) to classical plaster mortars. For the experimental program, we made our own formulas of plaster mortars to which natural organic polymers were introduced as additives; on these mortars the flexural tensile strength, resistance to compression and the adherence to the support layer, according to SR EN. The objective of the paper lies in identifying the natural organic polymer which has the highest impact upon the mechanical characteristics by improving them. (C) 2020 The Authors.
