The present disclosure provides a method for coating a composite structure, comprising forming a first slurry by combining a first pre-slurry composition with a first carrier fluid, applying the first slurry on a surface of the composite structure, and heating the composite structure to a temperature sufficient to form a base layer on the composite structure. The first pre-slurry composition may comprise a first phosphate glass composition and a low coefficient of thermal expansion material, wherein the low coefficient of thermal expansion material is a material with a coefficient of thermal expansion of less than 10×10.sup.−6° C..sup.−1.

To repair reinforced concrete easily and at low cost. An anticorrosion method includes infiltrating an anticorrosion solution held inside concrete of reinforced concrete into a vicinity of a reinforcing bar through the concrete to passivate the reinforcing bar, detecting that the anticorrosion solution is infiltrated to a surface of the concrete, and discharging, after detecting the anticorrosion solution, the anticorrosion solution to outside of the concrete to form an anticorrosive coating on a surface of the reinforcing bar.

The present invention provides a coloring solution for zirconia, which, when used on zirconia before firing of the zirconia, causes the zirconia to exhibit only a slight color difference before and after the firing and thus enables accurate prediction of the post-firing color tone of the zirconia. The present invention relates to a coloring solution for zirconia, comprising: a coloring agent (A) that is decolorized after firing of zirconia; and a metal ion solution (B), wherein, when zirconia is colored with the coloring solution and then subjected to firing, the color difference of the zirconia before and after the firing satisfies ΔL*≤5.8, Δa*≤2.4, and Δb*≤4.3.
