Amino resin composition

The invention is a method for preventing a hardened cementitious material from deteriorating or for repairing a deteriorated cementitious material, and more particularly to such method for the hardened cementitious material comprising metal materials to be corroded by a salt content and cause alkali-aggregate. It is characterized by applying a cement paste, mortar or concrete added with 1-25 weight % lithium nitride relative to the cement content so as to cover the surface of hardened cementitious material.

Method for preventing hardened cementitious material from deteriorating

An electroless plating method which comprises applying to a substrate a polymer composition comprising 100 parts by weight of a polymer and an organic metal complex in an amount of from 0.001 to 50 parts by weight as metal, pyrolytically decomposing the organic metal complex at a temperature of from 50.degree. to 500.degree. C. to form plating catalyst metal nuclei on the substrate, removing the dried polymer coating, and conducting electroless plating of the substrate.
