retarder

    Wet-mixed mortar retarding time

    Wet-mixed mortar is good for anything; that is, the retarding effect is only 25 or 26 hours, and what retarder can be added to extend a more prolonged time over 30 hours?

    Have you ever used a retarder that doesn't make dry-mixed mortar sticky?

    The dry-mixed mortar used Sodium gluconate for retarding setting in summer, but this material made the mortar sticky, which caused workers to complain. Do you know any non-stick retarders?
