Beneficiation of Natural Aggregates by Polymer Impregnation

Source

The use of polymer impregnation as a means of upgrading the physical and mechanical properties of natural aggregates was evaluated in a series of tests performed using four aggregates of varying quality. The strength of concrete cast with polymer impregnated coarse aggregate was also tested. Two monomer systems were used in the investigation, a methyl methacrylate-based system and a styrene-based system.

In general, significant improvements in the physical and mechanical properties of each of the four aggregates resulted from polymer impregnation. The strength of concrete cast with impregnated aggregates varied, being increased in some cases and decreased in others.
