文摘

Solidification of cationic resins in the Na+-form is investigated. Portland and blast furnace slag cements are compared. Deleterious expansion is observed with Portland cement only. Resin swelling is due to a decrease in the osmotic pressure of the pore solution. The consolidation rate of the matrix is a key parameter to prevent damage.
