The importance of using concrete as the main material in the construction of structures seems obvious. Due to the high cost of repairs, their durability is of particular importance. Permeability is the most important factor in reducing the durability of structures so that resistance to concrete permeability is the first factor in determining the service life of a structure.
. Since long time, researchers and civil engineers and metallurgists have been looking for additives to help them improve the mechanical properties of concrete and have made many successes. In addition to additives such as nano, the effect of exterior materials such as polyurethane paint on the durability of concrete can be investigated. Replacing part of the cement with filler material has been the idea of ​​many recent studies. Numerous reports indicate the use of these materials to improve the mechanical properties of concrete. Most attention has been focused on the use of silica.
The aim of this study was to investigate the effect of polyurethane paint on self-compacting concrete containing methacrylene and silica on durability of concrete used in structures.
