Abstract
An aqueous solution of 1-30 weight % alkali metal silicate and 0.005-10 weight % nitrite is stable and well permeable into hardened cementitious material. When applying said aqueous solution on the surface of hardened cementitious structure having metallic armatures embedded therein, it is possible not only to form surface layer improved in compactness, strength, hardness, waterproofing and weathering for preventing deterioration thereof and repair deteriorated cementitious material but also to prevent said metallic armatures from rusting.
