Polymer-Impregnated Cements, Mortars, and Concretes

It has been known since the 1950 s that the incorporation of various polymers into portland cement mortars and concretes can considerably improve many physical and chemical properties (American Chemical Society, 1973 American Concrete Institute, 1972, 1973a, 1975 Auskem and Horn, 1971 Coughlin et a/., 1970 Dikeou et a/., 1969,1971,1972 Dow Chemical 

Polymers may be incorporated basically in three ways (a) by adding a polymerizable monomer to a concrete or mortar mix, and then curing both concrete and polymer (b) by adding a latex or an aqueous solution of a polymer to a mortar, or concrete mix, and then curing the composition in the presence of the polymer and (c) by impregnating a cured mortar or concrete with a monomer, and then polymerizing the monomer using thermal or radiation catalysis.
