Additive reducing agent of filtrate to grout swelling clays only and clays and cements

摘要

Additive for the slurry of clays only and clays and cements with a view to reduce the filtrate, to reduce and stabilize the viscosity, delay the time of stiffening, limit the ressuee and the sedimentation of the solid constituents, which is characterizes in that it is a copolymer of the polymer and or ethylenic acid, alkali metal, is a continuation of between 500 and 20000, but then between 1000 and 6000. / p & & p & this additive is particularly advantageous in the field of civil engineering, of the building and public works and of the borehole.
