✦ Synopsis

Following various hydration times (l to Z8 days) concrete was impregnated with an epoxy resin system. For a given impregnation condition (vacuum, pressure and time), it was found that higher polymer Ioadings were achieved in specimens having shorter hydration times. Compressive modulus and compressive strength values for impregnated specimens were higher than their corresponding control values. Compressive modulus values appear to be a function of hydration time (up to 14 days) for impregnated specimens, but the modulus of l day impregnated specimens is considerably higher than that of all the controis (l to ~8 day). Compressive strength values appear to be primarily a function of volume loading, and I day impregnated specimens displayed compressive strength values of greater than 10,000 psi.

## Abstract Polymethylmethacrylate bone cement, containing either no added antibiotic, 0.5 g of Vancomycin, 1.0 g of Vancomycin, or 1.0 g of Tobramycin, was mixed either in air or a vacuum chamber. Following storage in a water bath at 37Β°C for 48 h, the specimens were tested in four‐point bending.
