gregates bound together by an appropriate organic resin system. Polymer concrete is a relatively low-cost composite material system that has been developed to be a technically viable alternative to porcelain for most high voltage electrical insulation applications. Polymer composites appear as useful materials for repair and protection of building structures, as well as for manufacturing pre-cast elements. PC has higher strength, greater resistance to chemicals and corrosive agents lower water absorption and higher freeze-thaw stability than conventional Portland cement concrete.
