Title:
PROCESS AND COMPOSITION FOR SHRINK CONTROL BY ADDITION OF GENERATOR
Document Type and Number:
Japanese Patent JPS5233921
Kind Code:
A
Abstract:
The contraction of aqueous hydraulic cement mixtures is controlled by the addition thereto of a gas generating agent capable of generating gas in the mixture without the addition of activators or other agents. Gas generation may be controlled over an extended period of time so that even slow setting cementitious mixtures may have their shrinkage or contraction inhibited during setting and hardening.
