Abstract

Procedure for enhancing the open setting time of hydraulic cement compositions, characterized in that it comprises mixing uniformly in pulverulent hydraulic cement, without essentially increasing the Blaine surface thereof, a solution containing an effective amount to increase the elasticity in open time of a additive formed by a condensed naphthalsulfonic acid, sulfonate or sulfonic acid derivative, the solution being in insufficient quantity to essentially alter the powdery appearance of said cement; and aging the resulting composition for a minimum of 15 minutes.
