Manufacturer's Product Description

Add strength and beautiful concrete color to both vertical and horizontal construction projects with CHROMIX Admixtures for Color-Conditioned Concrete. CHROMIX Admixtures are the water-reducing, set-controlling admixtures that produce durable and structurally sound architectural colored concrete.

CHROMIX Admixtures are suitable for all types of colored concrete projects from floors and hard landscapes to cast-in-place or precast walls. CHROMIX Admixtures are available in over 400 concrete color formulations in two convenient forms: CHROMIX P (powdered) and CHROMIX ML (mixed liquid in buckets and totes).

CHROMIX Admixtures provide
# A rich, diverse palette of concrete colors
# Evenly dispersed, consistent, streak-free concrete color throughout the concrete mix
# Repeatability -- batch-to-batch and project-to-project
# Superior, nonfading, permanent concrete coloring
# Increased concrete strength at all ages

Concrete colored with CHROMIX Admixtures may contribute to earning LEED® points under the Sustainable Sites category: 7.1 Heat Island Effect, Non-Roof for New Construction, Existing Buildings, Schools, and Core and Shell. Refer to the SRI chart for more information. In addition, most standard colors and many custom colors of CHROMIX P (powder) contain approximately 99% recycled material. Most standard colors and many custom colors of CHROMIX ML (mixed-liquid) contain approximately 95% recycled material.

SRI Values for CHROMIX Admixtures for Color-Conditioned Concrete - Standard and Custom colors.

CHROMIX Admixtures may contribute to earning LEED® points under the Sustainable Sites category: 7.1 Heat Island Effect, Non-Roof for New Construction, Existing Building, Schools and Core and Shell by having a Solar Reflectance Index (SRI) of at least 29 or greater as measured by ASTM E903 or ASTM C1549. Learn more.

Below are Solar Reflectance Index ("SRI") values for standard CHROMIX Colors.*
Note that SRI values from field installations can differ from those listed due to the materials used, finishing practices such as excessive burnishing, and a variety of other conditions. The color achieved is influenced by local materials. Scofield's Technical Data Sheet requires that a mockup be done under actual jobsite conditions using each color. Prior to beginning the job itself, each SRI should be determined and approved by a commercial laboratory that is equipped to perform SRI testing in accordance with acceptable ASTM standards.

Note: plain gray concrete has an average SRI of 35.

*Note that these are derived from laboratory tests using medium gray cement using a mix design of 5.5 sacks per cubic yard without pozzolans or other supplemental cementitious material.

**SRI values are calculated following ASTM E 903 and E 891 (100-point ordinate method), then the E 1980 SRI calculator following R. Levensen of LBNL using a materials emittance of 0.90 and typical ambient meteorological parameters.
