| Abstract [eng] |
Nowadays the concrete is one of the most important and most commonly used materials of the construction. Buildings, bridges, dams, tunnels, pires, chimneys, cleaning equipment are constructed using concrete. These buildings are constantly affected by aggressive environment. These structures must be resistant to frost, chemical, sea water effect. Concrete absorbs water, because concrete is less resistant to aggressive environments. In this study, est are carried out using additives which form crystals. This additive reduces the water absorption. The study is determined for w/c ratio with the additives and without it for influence of density, mobility, strength and water absorption. |
