Research progress of poly carboxylic acid concrete shrinkage reducing agent

摘要

The reduction mechanism, characteristics of molecular structure, and main factors affecting the reduction ability are reviewed in brief. The research progress of poly carboxylic acid concrete SRA are also reviewed. And based on the structure characteristics of poly carboxylic acid SRA, more functional poly carboxylic acid SRA is the main development direction in concrete shrinkage agent reducing in the future.
