ABSTRACT:
An expandable polymer concrete or mortar composition, and process for producing it, which allows the use of low temperature cure resins by incorporating a substituted mineral which is able to expand in the polymer concrete mix so that the dilation of the mineral will counteract the shrinking effect of the curing resin. The substituted mineral may be selected from the montmorillonite group and is produced by substituting its water of hydration with a higher volatility composition such as ammonia.
