Document Type and Number:
WIPO Patent Application WO/2019/053782
Kind Code:
A1
Abstract:
Provided is a dispersion-maintaining agent for a hydraulic composition capable of maintaining the fluidity of the hydraulic composition even when a long time has elapsed since kneading and with little curing delay.
