Integral Colors - Page 12

PRODUCT DESCRIPTION
QC INTEGRAL COLORS consist of colored admixtures and are developed for use in ready mixed concrete. The product is made of the highest quality pigments, as well as other ingredients designed to enhance the color and improve the pigment dispersion, workability and finishing performance of the concrete and offset water demand caused by pigments. QC INTEGRAL COLOR pigments meet or exceed ASTM C 979. This coloring method can be utilized for concrete flatwork applications (salt finishes, broom finishes, rotary finishes), as well as vertical surfaces and other types of architectural concrete. QC INTEGRAL COLOR may also be used in conjunction with admixtures conforming to ASTM C 494, Types A, B, D and F. QC INTEGRAL COLOR is also compatible with air-entrained admixtures conforming to ASTM C 260.

HIGH PIGMENT QUALITY RESISTS FADING
IMPROVES WORKABILITY
DISINTEGRATING BAGS
PACKAGED WITH REMOVABLE BATCH LABELS FOR IMPROVED QUALITY CONTROL

DIRECTIONS FOR USE
QC INTEGRAL COLORS are packaged in cubic yard/meter units for specific cement ratios. One bag of QC INTEGRAL COLOR contains the proper ingredients for one cubic yard or cubic meter of concrete. Custom packaging is available upon request. Make sure to specify the proper cement content when ordering. We do not recommend flyash mixes.
FOR CONVENTIONAL READY-MIXED PLANTS: The drum must be cleaned and approximately 1/3 (one-third) of the mix water and a portion of the aggregates needed should be added to the drum. Do not use slurry water or reclaimed aggregates. Add the correct number of QC INTEGRAL COLOR bags to the drum and charge at mixing speed for three minutes or until all bags have been broken up and a color slurry is visible in the drum. Add the balance of ingredients (water, aggregates, cement and admixtures) into the truck and thoroughly mix the load before final slump adjustment. At the job site, re-mix the load for at least 5 minutes to insure concrete consistency. Do not exceed maximum allowable revolutions.
FOR CENTRAL MIX OR PREMIXED BATCH PLANTS: Add 1/2 (one-half) of the total batch into a clean ready mixed truck drum. Do not use slurry water or reclaimed aggregates. Add the correct number of QC INTEGRAL COLOR disintegrating bags into the drum and mix at high speed for at least 3 minutes. Batch the remaining concrete into the truck and mix again for at least 3 minutes before final slump adjustment. At the job site, re-mix the load for at least 3 minutes to insure concrete consistency. Do not exceed maximum allowable revolutions.

ADDITIONAL CONSIDERATIONS FOR CONSISTENT COLOR:
• Color loads should never be smaller than 3 cubic yards.
• Add reinforcement fibers after the color load has been thoroughly mixed. This reduces the potential for fiber/color balling.
• Use one source for cement, aggregates and pozzolans throughout the job. Monitor and control incoming material consistency.
• Do not use calcium chloride-based admixtures. Non-chloride admixtures may be used.
• Wash out all drums before loading. Keep slumps consistent. Minimize driver-added water.
• A 4 to 5 inch slump is recommended. Maintain the same water/cement ratio. Required higher slumps should be achieved by using water reducing or plasticizing admixtures and NOT by adding water because this will adversely affect the color.
