Installation
Preparatory Work
The mixing shall conform to
ASTM C94, the portland cement ASTM C150, and the coarse
and fine aggregates
ASTM C33. Color addition should not exceed 10% of the weight
of the cement conforming to ASTM C979.
Application
A power mixer should be used to provide thorough
mixing and dispersing of color. To provide consistent and
uniform color a sound method is: (1) Load the mixer with
selected mix design of portland cement, coarse, and fine
aggregate. (2) Add the designated amount of DCS Cement Color
by weight along with the cement for the mix and agitate at
full speed for several minutes. Any change in proportioning
the amount of water, aggregate, sand and color to the cement
and/or type of cement and aggregate used on the same job
can result in variation of color tone in the finished job.
Before
loading, agitator should be checked for residual water
from cleaning.
Maintenance
After the concrete has cured for a period of at least 28
days various “proprietary sealers” may be used
for protection against the elements. Please check with
the sealer manufacturer for aesthetic changes the sealer
may cause to the appearance of the Colored Concrete Surface.
