| Research Abstract |
Paying attention to the surface protection method for a concrete structure, it aimed at clarifying their character and effect in application of surface penetrant material and low-temperature electric arc spraying. As a results, the effect of combination type surface penetrant was better than mixed type surface penetrant and low-temperature electric arc spraying. Main results were as follows. 1) In surface penetrant, the best effect of impregnation depth was in case of coating with standard coating quantity. 2) The curing period from coating to the start of the test was enough in 2 weeks. 3) In combination type surface penetrant, the best ratio of silicate type to silane type was 2:8, and the effect on chloride induced deterioration was better than that of carbonation. 4) Mixed type surface penetrant and low-temperature electric arc spraying were not better than the effect of combination type surface penetrant.
