Development of compositions of modified concrete with improved water-repellent properties for underground parts of buildings

Expansion of Concrete Functionality due to Use of New Hydrophobic Additives

“…Increase of the structures and buildings service life in aggressive medium is possible due to the concrete modification by polymer materials both internally and by external waterproofing. By combining concrete modifications with polymer additives and integral waterproofing by polymer films, the composition acquires increased physical mechanical and anticorrosion properties [3,15,16].…”

“…Specialists in the field of concrete and reinforced concrete corrosion found that the main factor for improving the corrosion resistance of the concrete is to reduce the porosity (permeability) of concrete. Compositions of highly-persistent low-permeability concrete with a low W/C and increased cement consumption, with adding superplasticizers, refer to concrete with increased corrosion resistance [15,16]. The increase in density by reducing the W/C is a universal way to increase corrosion resistance for all environments except acid.…”

“…Acrylic polymer additive characterized as a hydrophobic plasticizing modifier containing a microfill pigment and mineral supplement will have a positive effect on improving the corrosion resistance of concrete. That will make it possible to use the modified formulations in the field of hydraulic structures [15,19].…”
