SO…WHAT IS CHROMIX® G?
CHROMIX® G Admixtures for Color-Conditioned® concrete are free-flowing concentrated pigment granules designed to permanently color concrete and other cementitious materials. They can be poured directly into concrete mixes, conveyed by gravity feed or pneumatic equipment, or pre-dispensed into disintegrating bags that can later be added directly to the concrete mix as a single unit.
CHROMIX® G Admixtures can be used to color cast-in-place, precast, and dry-cast concrete floor slabs, walls, steps, sidewalks, curbs, columns, pavers, and other decorative objects.
Once you decide you want integrally colored concrete, your 1st thing you must remember is to call your local Jarco Supply branch.
BATCHING CONCRETE WITH CHROMIX® G ADMIXTURES
CONCRETING GUIDELINES
CHROMIX® G Admixtures for Color-Conditioned® Concrete are designed to have minimal effect on concrete plastic and hardened properties, and to minimally interact with other concrete admixtures. As chemical admixture interactions cannot be predicted, we recommend always conducting test samples using the actual materials to be used to ensure proper slump, air content, and performance of the mix.
RECOMMENDED DOSAGE
Color selection will determine the ratio of base colors needed, and color saturation, and intensity will determine the amount of granules required. Typical dosages range between .0 to 5.0 pounds of granules per 94 pound sack of cement. If supplementary cementitious materials such as fly ash or blast-furnace slag are used in the mix, their weight must be added to the weight of the cement when determining the correct dosage.
Jarco Supply has a Chromix G color machine onsite for your Made-To-Order integral color needs. Our color machine is stocked with all Scofield and Butterfield colors and also has the ability to color match almost all major color manufacturers. Call today and our color experts will help guide you to the correct color and dosage rate based on your concrete mix design.
MIXING
CHROMIX® G Admixtures for Color-Conditioned® Concrete should be added first with dry materials and wet drum – on short loads concrete added first and color dispensed on top of load. For proper mixing, please allow 5-10 minutes and/or 130 drum revolutions while turning at mixing speed. This allows for the color to thoroughly mix through the concrete and the drum fins to totally pulverize the bags. We recommend not speeding the drum to maximum speed as the bags have a tendency to ride the fins around instead of pulverizing them completely.
Once the concrete has been properly mixed, we recommend testing the concrete to ensure proper slump and air content. The last thing you want to do is pour out of specification decorative concrete. Concrete that is poured too wet will not gain sufficient strength and it can greatly dilute and lighten the chosen color.
