Title:
DISPERSING AGENT FOR HYDRAULIC COMPOSITION
Document Type and Number:
Japanese Patent JP2003002714
Kind Code:
A
Abstract:
To provide a dispersing agent which imparts the stable dispersibility and dispersion durability particularly to a lean-mix hydraulic composition even when there is a temperature change in the hydraulic composition and a quality fluctuation in fine aggregate, little causes bleeding and improves the operability as well.
This dispersing agent for hydraulic composition contains a copolymer which is obtained by copolymerizing specified two kinds of polyalkylene glycol (meth)acrylates 1-a, 1-b and a specified monomer 1-c such as maleic acid in a specified weight ratio.
