Polyester polymer concrete shrinkage

High-temperature cement formulations are basically polymer concrete. Mainly unsaturated polyesters or vinyl ester resins with allylphthalate as vinyl monomer are in use [927]. Cming is achieved with peroxides, which decompose sufficiently fast at temperamres between 120° and 200° C. Polymer concrete requires additional materials, which compensate shrinkage. 

The vinyl ester resins have lower shrinkage and are generally less rigid than many of the polyester resins. Vinyl ester novolac is a premium vinyl ester resin. Any of the vinyl ester resins can be formulated to produce a polymer concrete that will be capable of resisting normal atmospheric pollution.
