Adding Liquid Colors

HOW TO MEASURE AND ADD LIQUID PIGMENT TO A CONCRETE BATCH:

Most customers prefer using dry powder pigments but if used properly, Liquid Pigments can be cleaner and just as easy to use, even with small Concrete Batches.

DO NOT measure pigment into a cup and then add to the concrete batch trying to rinse out the remainder.

Instead take a small amount of Sand from the main Concrete Batch Sand, and put this in a small container onto the scale.  Dig a small hole into the sand in the middle of this container.  Tare the scale to zero. Then draw an amount of Liquid Pigment into a good size syringe (10-50 CC). Then add the liquid pigment directly into the sand on the scale until the correct weight is added.

Take this sand, with the pigment, from the scale and dump this back into the main quantity of Sand for the Batch.

This has eliminated any need to rinse out a container - 100 % of the measured Liquid Pigment is in the Batch.

SUPER COLORS - The "SB" Colors

Our wettable super red, super blue, super green, and blacks should be added towards the end of the mix cycle, after cement, and before CSA cements and fibers.

DISPERSION/DISPERSION/DISPERSION:

Complete dispersion of each ingredient to 100 % is the ultimate goal - not 94 or 97 but 100 %. Notice the small concrete chunks missing from most older highways/bridges. The concrete is likely good quality but not to 100 %. This is also possible in small scale concrete countertop pours - that 3 % may be the part next to the sink faucet cutout. After all your efforts, a crack or break during install is often due to lack of complete dispersion of each and all components.

The extra little squirt of water at the end of a batch means you restart the clock to get that extra water completely dispersed to 100 % throughout the batch or it becomes a weak spot.

Same goes for Admixtures and Pigment. Of course with pigment, complete dispersion may not be desired for variageted effects which is a different issue. Extra mix time may mean the difference between perfect surface and dreaded pinholes.

When adding Carbon Black powder, stop the mixer and add the Black into the moist Sand and bury the Black Powder completely. Restart the mixer which should reduce the amount of dust created.
