Abstract

Lime compositions with polysaccharide additives are being studied. The results are aimed at creating a new lime plaster composition with improved performance properties. Materials and methods. Standard methods for studying rheological and technological properties were used. Results. The influence of polysaccharides on changes in the rheological properties of lime compositions has been established. It has been established that the introduction of a polysaccharide additive (hydroxyethylcellulose) helps to accelerate the development of plastic strength. The results of infrared spectroscopy indicate a higher content of calcite in the sample with the addition of polysaccharide. The absence of chemical interaction between lime and polysaccharides has been established. Conclusions. The introduction of polysaccharide additives promotes the formation of a structure that improves the performance properties of the lime composite.
