The procedure used for producing precast slabs of polymer impregnated concrete (PIC) and described in this report was generally satisfactory from an operational standpoint. A strength loss of 14%, attributable to the drying step, was observed in PIC cylinders; however, residual strengths for this class of concrete were satisfactory. The freeze-thaw durability of PIC specimens was essentially the same as the excellent performance exhibited by the control concrete. The average maximum depth of polymer impregnation observed in cores from the slabs was 1.0 in. (25 mm). The impregnated zone was found to contain a series of discontinuous microcracks resulting from the polymer treatment. These cracks allowed chloride ion penetrations at a depth of 0.8 in. (19 mm) that equalled or exceeded those at this depth in the control concrete. Additional research with experimental slabs is recommended with the objective of eliminating the microcracking associated with the impregnated zone.
