Abstract:
|
The condition of six concrete bridge slabs that had been in service for three years was evaluated. The top 2 in. of the four slabs that had been impregnated to a depth of about 1 in. with a methyl methacrylate and trimethylolpropane trimethacrylate monomer, and that were subsequently polymerized, was found to exhibit an average permeability to chloride ion which was 18% of that exhibited by the top 2 in. of the two control slabs that had not been impregnated. Electrical half-cell and resistance measurements were the same for the impregnated and control slabs.
