SELECTION OF CHEMICAL GROUT FOR MATTMARK DAM

FOUR CHEMICAL GROUTS, TWO NEARLY IDENTICAL SODIUM SILICATES (ALGONIE AND CONSONDA), AND 2 POLYMERS (BAKELITE AND POLYTHIXON) UNDERWENT EXTENSIVE LABORATORY EVALUATION. FIRST, THE GROUTS ALONE WERE EXAMINED WITH REGARD TO VISCOSITY-TIME BEHAVIOR, GELATION TIME, TEMPERATURE INFLUENCE, STABILITY, DEFORMABILITY, AND TOXIC PROPERTIES. BAKELITE WAS ELIMINATED BECAUSE OF ITS RIGID DEFORMABILITY. THE SECOND STEP TESTED GROUT-SOIL INTERACTION: THE INJECTABILITY AND PERMEABILITY REDUCTION OF ALGONITE AND POLYTHIXON WERE EXAMINED IN LABORATORY INJECTION TESTS. BOTH GROUTS REDUCED PERMEABILITY BY AN ORDER OF MAGNITUDE, BUT POLYTHIXON HAD TO BE ELIMINATED BECAUSE OF ITS LIMITED INJECTABILITY. FINALLY, LONG-TERM TEACHING TESTS OF SYNERESIS. SATISFACTORY RESULTS LED TO THE RECOMMENDATION OF THIS GROUT FOR EVENTUALLY SUCCESSFUL APPLICATION. THIS EVALUATION PROCEDURE IS GENERALLY VALID FOR ANY GROUT SELECTION. /AUTHOR/
