Advantages

1. Cost Performance: Economy and versatility are the primary reasons why ochre and umber pigments have enjoyed over 110 years of success in the pigment industry.
2. Economical: Ochre and Umber are the most economical buff colorants available today. Ochre based blends repeatedly outperform synthetic iron oxide colors  where earth tone shades are desired. On jobs ranging from a residential driveway to a 100,000-plus cubic yard drainage canal, ochre has been chosen because of its economy and performance quality.
3. Permanence: Because Ochre and Umber are iron oxides, their color is permanent. They will not fade or wash out. The cave paintings by prehistoric man, as well as the earth pigments used extensively in Renaissance art, attest vividly to the beauty and permanence of natural iron oxide pigments.
4. Ease of Use: As natural pigments, Ochre and Umber blend easily and uniformly in all applications.
5. Custom Colors containing Ochre and Umber as a base can be formulated to create a new “natural” range of color.

Applications

1. ADMIXTURES: Water reducing agents, dispersing agents, retarders, or air entraining agents may be used along with 548. These admixtures, if used, should be added at the batch plant in the type and amount specified by the mix designer to achieve the intended results considering the raw materials to be used. Each load of colored concrete should contain the same dosage of admixtures. Avoid the use of calcium chloride or other admixtures that would contribute to efflorescence. NOTE: Admixtures will effect final color.
2. BATCHING: Add 548 by weight, directly into the mixer along with aggregate, sand, cement, and water. While adding 548, the transit mixer should operate at charging speed or at mixing speed for 5-10 minutes or from 50 to 100 revolutions.
3. PLACING: All colored concrete should be placed at the same slump, using the lowest slump compatible with a workable and placeable mix.
4. FINISHING: Finishing should be done carefully to insure color uniformity. A broom, rotary, or textured finish is recommended. Over troweling should be avoided. No dusting of cement or sprinkling of water should be used when finishing colored concrete.
5. SAMPLES: We recommend that a sample be made with materials that will be used on the job in the proportions specified as the color of the cement, sand, and aggregate will influence the final color. All samples should be cured before a final decision is made, as the wet un-aired concrete will be a darker color than cured concrete.
