Abstract


Bases under the law of solubility product, the pores of the cement mortar are refilled by impregnation with two salts that form another insoluble salt.
The number of treatments to be underdone and the drying temperatures more suitable in each case.
The calcium salts like impregnants and urea sodium oxalate and sugar like precipitates are employed, obtained in each case the corresponding pores are occupied, which depends generally on the number of treatments and in particular the drier temperature.
