Abstract:
This research concerns the release of liquid methyl methacrylate from inside of the porous fibers into hardened concrete matrices to reduce permeability. Low heat is applied to the composite. It melts the wax coating on the fibers and dries the matrix, both of which act to move the methyl methacrylate and wax out into the matrix surrounding the fiber. The heat is increased, and the monomer becomes polymerized in the dispersed state into the matrix. Research results showed reduction in matrix permeability.
