Abstract: It was shown that: (1) stress-strain behavior could be varied over a wide range, from ductile to brittle, by using combinations of a plasticizing or crosslinking comonomer with methyl methacrylate, or both; (2) the presence of a realistic level of salt (up to 1%) in concrete has little effect on polymer loading and mechanical properties, but requires more rigorous drying; (3) while high temperatures (750°F) accelerate drying but decrease strength, subsequent polymer impregnation essentially yields a PIC with properties similar to a conventionally dried material; and (4) salt penetration (short-time, static) in mortars is reduced an order of magnitude by polymer impregnation, regardless of whether the polymer is glassy or rubbery. Thus, a strong PIC can be prepared under a variety of drying and salt contamination conditions and the mechanical behavior of PIC can be tailored to various specifications.
