Retarding admixture for concrete |
摘要 |
An admixture which delays the setting of concrete within a ready-mix truck is disclosed. The admixture is comprised of a mixture of glucono delta lactone and cornstarch and produces exceptional retarding results at a reasonable cost. The corn starch is relatively inexpensive and is used as a filler material to reduce the overall cost of the admixture.
