1lb per 80 lbs concrete.
The simple answer is yes. Please read the installation guide. Here is the snippet from that guide about mixing: Mixing: 1. Thoroughly blend the color with water prior to adding dry material. 2. Caution: Care must be taken to keep proportions of materials the same from batch to batch. Color will tend to even out over time. 3. Use 1 lb (.045 kg) of Sakrete Cement Color per 80 lb (36.2 kg) or 60 lb (27.2 kg) bag of Sakrete Concrete, Sand or Mortar Mix. 4. One pound of Cement Color will yield a darker color in a 60 lb bag than in an 80 lb bag. If a lighter color is desired use less cement color. 5. For custom field mixes, use up to 7 lb (3.18 kg) per 94 lb bag of Portland cement and up to 5 lb (2.27 kg) per 70 lb bag of masonry cement.
The color is based on mineral oxides. The same thing that colors rock naturally. I would not be too concerned with the use in a fish pond, it you are referring to a small, decorative pond, where the water gets replace some from time to time. Some of the color might leech into the water (not visibly) but I would not worry too much. What is a larger concern, if you are making a pond out of concrete, is other chemical present in the concrete. Concrete will raise the alkalinity of the water somewhat, at least at first, so keep an eye on the ph to insure it stays within good numbers compatible with you kind of fishes. Concrete will add lime to the water for a while, I would let water sit in the pond for some days, it not weeks, then drain and replace it, before adding fishes.
The color will appear more vivid and pure with white cement, but that does not been better, just different, What is "best" depends on your tastes!
Yes you can
Sakrete Customer Service answered that you have to mix the color into the water. Sakrete instructions say to add the color to the dry cement mix: "MIXING: Thoroughly preblend the SAKRETE® Cement Color with the dry powder cement product before adding mix water." (https://images.homedepot-static.com/catalog/pdfImages/45/45342905-d9a0-4656-8b4d-7342a4fe471e.pdf) So, which is the correct way?
This material will not determine when the concrete or mortar can be placed. That is up to the manufacturer of the concrete and or mortar materials. Our concretes and mortars need a minimum of 50 degrees for the first 48 to 72 hours.
It is going to vary with the concrete you use. Concrete has cement in it, and aggregates (sand, gravel, rocks etc.) To a small degree, the aggregates can affect the color. However, it is the color of the cement used in the concrete mix, that has the largest effect on the finished color. The color of the cement, varies from one location to another, and even from one bag to another. If your concrete all comes from the same batch, then the color variation will be small. Most cement is some shade of gray, and that subdues and darkens the color. When you mix the color into your concrete, it will be darker that when it cures. Think about how much darker a sidewalk looks when it is wet, than when it is dry, that is about the difference in shade between concrete being mixed, and concrete that has cured. If you decide to seal your cured concrete with a wet look sealer, then it will be similar to what the concrete looked like when it was being mixed.
About 25 to 30 pounds.
Yes you can put it in a mixer. I typically mix it with the water before adding the concrete to my mixer. It is a little difficult to judge just how much to add to make the color right. It is also difficult to match the color of one batch to the next. Trial and error will get you a recipe you can follow to get the color just right. Also, my mixer is a metal mixer. Some concrete sticks to the side walls as well as to the baffles inside. I often have to turn it off and scrape these areas manually and then remix to get a consistent color. A plastic bin mixer may be better with the color.
