2. The nature of concrete can be determined through petrographic examinination.

3. Defects in Concrete

4. Physical Signs of Defects “Corrosion occurs quite simply because sometimes the steel reinforcement within the concrete is not properly protected against the effects over time of water, acids and salts.”

5. Chemical Attack

6. Chloride Diffusion

15. Japanese Bridge Deck

18. CONCLUSION From this experimental investigation, it was clear that the Xypex Concentrate crystalline treatment was effective in improving the durability of the concrete deck plates that are stressed by continuous and repeated load. It was confirmed that cement crystals are increased in the cracks of the bridge deck and hence a waterproofing effect has resulted.
