Kind Code:
B2
Abstract:
PURPOSE:To provide a cement curing agent excellent in kneadability, etc., with cement powder components, and capable of giving cement cured products having high mechanical strength. CONSTITUTION:This curing agent consist of a polymer-X ray contrast medium composite and/or polymer-filler composite which is obtained by polymerization of an unsaturated carboxylic acid monomer or its mixture with another polymerizable unsaturated monomer in an aqueous medium in the presence of X-ray contrast medium powder and/or filler powder. This curing agent is excellent in operability and kneadability in its mixing with dry cement powder components and is adequately kneadable in a short time without the need for any skill. Use of this curing agent produces cement cured products excellent in mechanical strength such as crushing strength with uniform ultimate performance.
