Annotation:

The service life of concrete can be significantly increased by properly defining the design characteristics, selecting the right starting components, and accurately calculating the composition of the mixture taking into account the required performance indicators,. strict adherence to technological stages—from manufacturing to installation, compaction, and proper maintenance during curing and subsequent use—is provided. Practical tips for achieving maximum efficiency at each of these stages are provided. It is emphasized that the resistance of the material to destruction increases proportionally to the decrease in permeability, which largely depends on the level of open porosity and the average pore diameter.

Keywords: durability, concrete mix, porosity, frost resistance, water impermeability, concrete, cement, hydration.
