A1
Abstract:
A concrete modifier, characterized in that it comprises an aqueous lithium silicate solution and an alkali metal ion source. The concrete modifier allows the prevention or inhibition of the deterioration by the freezing and thawing action, the salt attack or a combination thereof by the use of a relatively simple process wherein it is only applied on the surface of a newly constructed or existing concrete structure, and it permeates into a deep inside part of a concrete structure without changing the surface design thereof (with the retention of the state of the surface immediately after placing) and exhibits high durability.
