The Influence of the Structure on the Destruction Mechanism of Polymer-Cement Plaster Coating

Abstract

The article considers the influence of the structure of polymer-cement plaster coating on the nature of its destruction during the operation of the wall structure. It was shown that the use of purposefully selected components of the mixture (RPP, polymer fiber, cellulose ethers, fine aggregate with a low modulus of elasticity, etc.) made it possible to increase the uniformity of its structure and contact area with masonry, reduce the number of cracks during hardening, and slow down their development during operation, increase the durability of it and the wall structure. The durability of the wall structure largely depends on the number of defects in the plaster coating and the contact area between it and the masonry.

A Calculation Model for Determining the Bearing Capacity of Strengthened Reinforced Concrete Beams on the Shear

“…Basalt fiber, aramid fiber, and carbon fiber mesh were selected as reinforcing materials to study the concrete's early cracking resistance and the mortar's early cracking characteristics. Another method is installing a polymer-cement coating on wall structures [19]. The influence on the durability and destruction of the tested wall elements was described.…”
