The shrinkage is a significant phenomenon in concrete structures. The article is aimed at monitoring the shrinking of concrete slabs under laboratory conditions. The results of laboratory research aimed at unreinforced slabs strains affected by the non-homogeneity of concrete are mentioned in the article. According to these results another research of shrinkage influence on strains and deflection of concrete slabs reinforced by steel, resp. GFRP reinforcement has been prepared. The results of this research confirm the significant effect of concrete non-homogeneity on the formation of strains and deflections due to shrinkage.

Organic Corrosion Inhibitors

In this paper the efficiency of two organic corrosion inhibitors, a migratory and an admixture inhibitor, was evaluated by electrochemical techniques in solutions simulating the interstitial electrolyte of concrete and on concrete slabs exposed to natural environmental conditions over a five-year period. From obtained results, the usefulness of the two products is discussed aiming its application in new structures to prevent chlorides induced corrosion and as a curative method for repairing reinforced concrete structures contaminated with chlorides and affected by reinforcement corrosion.
