  • can this be used in quikrok..a hydraulic fast set cement grout to slow the set time......what would the amount used be for 90 degree and above temp. ..we only mix about 1 lb at a time ...and use in dry glazing for glass track

    Dosage per 100 lbs/100 kg cement:
    Air Temperature
    40 to 69 °F ( 4 to 20 °C) 2 fl oz (130 mL)
    70 to 79 °F (21 to 26 °C) 3 fl oz (196 mL)
    80 to 89 °F (27 to 32 °C) 4 fl oz (260 mL)
    >90 °F (>32 °C) 5 fl oz (326 mL)

    For 90 degrees and above, you would be using .05 oz

  • will this be ok to use in quikrok a fast set cement grout to slow set time

    Yes, this will slow the cure of any cement based product.

  • How much per yard for 1hr delay

    The dosage will vary with temperature, density, and ratio of cement in the batch mix. 3 fl oz/100 lbs (196 mL/100
    kg) of cement will extend the initial setting time of portland cement concrete by approximately 2 to 3 hours at 70
    °F (21 °C). For longer setting times or in higher temperatures, additional retarder may be needed. For shorter set
    times or in cooler weather, use less.

    Dosage per 100 lbs/100 kg cement:
    Air Temperature
    40 to 69 °F ( 4 to 20 °C) 2 fl oz (130 mL)
    70 to 79 °F (21 to 26 °C) 3 fl oz (196 mL)
    80 to 89 °F (27 to 32 °C) 4 fl oz (260 mL)
    >90 °F (>32 °C) 5 fl oz (326 mL)
