Abstract:
Polymer impregnated concrete (PIC) was overlaid with a low slump dense concrete (LSDC) or a latex modified concrete (LMC). Flexure strength, compressive strength, and freeze-thaw durability data were obtained on the composite specimens. Flexural data indicated a strong bond was established between LSDC, LMC, and PIC. Compressive strength data indicated the bond was weaker for the LMC than the LSDC. Freeze-thaw data showed that a durable bond was established between the PIC and the LSDC whereas the bond failed between the PIC and the LMC.
