Title:
水硬性組成物
Document Type and Number:
Japanese Patent JP4152713
Kind Code:
B2
Abstract:
To provide a dispersing agent for hydraulic composition which has performances hardly affected by the temperature change, giving excellent workability and filling property and particularly suitable for super high strength concrete.
The dispersing agent is made by using two kinds of copolymers each containing a polyalkylene glycol (meth)acrylate-based monomer (a) in which alkylene oxide average addition mole number is in a specific range and a specific unsaturated monomer (b) as structural units so that the product of each alkylene oxide average addition number and the weight percentage of (b) to the sum of (a) and (b) expressed in terms of acid type has a specific relation.
