- Abstract
- A fracture mechanics study of plain and polymer impregnated mortars has shown that the (slow and rapid) macrocrack propagation resistance of these materials is not significantly affected by mortar processing variables, such as water/cement ratio and curing time,but is strongly enhanced by polymer impregnation. Acoustic emission measurements have indicated the important role of microcracking in the fracture of both plain and impregnated mortars; with the susceptibility to microcracking being substantially retarded by polymer impregnation.
