Outline of Final Research Achievements

The method for estimating thickness of water repellent layer formed in concrete with silane type surface impregnation material was improved. It was possible to improve the estimation accuracy.
And, the performance of the water-repellent layer was evaluated for each property of water absorbing property, water permeability and freeze-thawing resistance. Various performances are improved by applying surface impregnated material. There was no influence of mix proportion of concrete on water absorption and freeze-thaw resistance. Water permeability of low quality concrete was lower than ordinary concrete. So, the influence of quality of concrete was observed.
