Installation
Preparatory Work
The mixing shall conform to ASTM C94, the
portland cement ASTMÊC150, and the coarse and fine
aggregates ASTM C33. Color addition (dry weight basis) 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 coarse, and fine aggregate. (2)
Add the designated amount of DCS Liquid Cement Color by weight
or volume as desired. Add 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. |
