This paper studies the effect of zinc corrosion in fresh concrete on the process of its hydration and evolution of common mechanical properties. Process of hydration was monitored by temperature measurement of hydrating concrete contaminated with zinc powder (0.5; 5.0 wt. %) in closed system. Mechanical properties were monitored in similarly contaminated concrete samples (compressive cubic strength, compression modulus of elasticity). The results suggest that zinc corrosion products retard the concrete hydration and evolution of mechanical properties, however, forming hydrogen also has some negative effect. |
