Normally, deterioration in the concrete structure is due to carbonation and chloride ion attack. Therefore, concrete structure is needed to surface protection for increase durability using impregnant. Impregnant classify into two large groups in polymeric and silicate materials. Silicate impregnant is included silane and alkali silicate(sodium and lithium silicate). Thus, this study is concerned with self cleaning hydrophilic property of concrete structure using silicate impregnant. From the experimental test result, TEOS and lithium silicate make good use of hydrophilic impregnant. |
