Title:
CONCRETE PLACEMENT JOINT AGENT
Document Type and Number:
Japanese Patent JP2016223102
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete placement joint agent that gives high adhesive strength to a concrete placement joint.SOLUTION: A concrete placement joint agent of the present invention includes a polymer (A) and water (B), the polymer being obtained by polymerizing a compound (a1), which is obtained by a reaction between an unsaturated monomer (a1-1) containing a glycidyl group and an aliphatic tertiary amine (a1-2), with an unsaturated monomer (a2). The polymer has a glass transition temperature of 50°C or less. The concrete placement joint agent gives high adhesive strength to a concrete placement joint, and demonstrates high flexural strength when a trisecting point loading test for flexural strength of concrete is performed pursuant to JISA1106:2006.SELECTED DRAWING: None
