Abstract
An additive for swelling clay grouts and cement-swelling clay grouts, intended to reduce the filtrate, lower and stabilize viscosity, retard rigidification time, limit sweating and sedimentation of the solid constituents, is an alkaline ethylenic acid polymer and/or copolymer, with molecular weight between 500 and 20,000, but preferably between 1000 and 6000. This additive is especially advantageous in the fields of civil engineering, building, public works and drilling.
