Polymer concrete compositions

The mechanical properties, the corrosion stability, and some useful properties are the reasons for the continuous interest shown in polymer-concrete composites by various design, research, and production organizations. The most important types of polymer-concrete composites are polymer-impregnated concrete (PIC), polymer-cement concrete (PCC), and polymer concrete (PC). 

The particular characteristics of compatihiHty of poly(vinyl acetate) with cement have led to wide use of this latex as a main component in polymer-mortar and polymer-concrete composites.

Other applications of rosin derivatives and pol5miers include emulsifiers for pharmaceuticals and cosmetics [129, 130], flotation oils in the phosphate industry [131] and the formulation of polymer-concrete composites for the construction of temporary and semi-permanent military structures in arid zones [132].

B) Polymer-cement concrete is a modified concrete in which a part of the cement binder is replaced by organic polymer. It is produced by incorporating a monomer, prepolymer, or dispersed polymer latex into a cement-concrete mixture. The process technology used is similar to that of conventional concrete and has the advantage that it can be cast in place for field applications. Most of the polymer-cement-concrete composites are based on different kinds of lattices obtained especially by emulsion polymerization. The lattices are aqueous emulsions containing polymer particles such as SBR, NBR, PVAc, copolyesters of AA-MAA, and PAA-PMAA-SBR. The compatibility of SBR, PVAc, and acrylic lattices with Portland cement produces particular characteristics that led to wide use of this component as polymer-concrete composites.
