Abstract(s)
Ensuring the durability of buildings and structures is of great importance in the construction industry. Degradation of building structures has significant economical impacts and requires a lot of resources. Despite a large number of works devoted to the corrosion resistance, the question still relevant today.
Common strategies for increasing the corrosion resistance of concrete in an aggressive environment is the use of products to slow the diffusion or penetration depth of contaminants in the cement matrix [1].Corrosion resistance in a cement based matrix can be increased, through judicious selection of binders and the use of polymer additives which react with the cement matrix creating various mechanisms that reduces or eliminates the conduction contact area for corrosive components of the environment [1]. The effect of additives on the properties of polymer composites of cement due to their chemical composition and curing conditions is known. Polymer additives, depending on the dosage may either increase or decrease the strength characteristics.
The emergence in the construction industry of the Republic of Belarus of new types of polymer additives justifies the current research on their use and their impact on the physical and mechanical properties of cement-based products, including their corrosion resistance.
The current study focuses on polymers based on both vinyl acetate-ethylene copolymer and acrylic emulsion polymer as a modifier for cement based composites
