▎ 摘 要
NOVELTY - Concrete water retaining agent comprises 20-30 pts. wt. polycarboxylic acid , 2-6 pts. wt.tea saponin , 10-20 pts. wt. cellulose ether, 5-14 pts. wt. dispersible emulsion powder and 30-40 pts. wt. inorganic water absorbing material. USE - The concrete water retaining agent is useful in concrete (claimed). ADVANTAGE - The concrete water-retaining agent improves the water-retaining performance of the concrete and solves the self-drying shrinkage problem of the concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the concrete water-retaining agent comprising uniformly mixing the raw materials.
