- Step 1: The truck mixer drum must be completely clean with no leftover water or aggregate before mixing a batch of colored concrete.
- Step 2: The slump must range from 90 mm to 100 mm (3 1/2" to 4"). If air is entrained, it should range from 5% to 7%.
- Step 3: Put the drum in reverse (discharge) to shift the concrete toward the back of the drum and then stop the drum. Place the bags of pigment directly onto the concrete, then place the drum in forward (mix)
- Step 4: Let it turn slowly (5 rpm) for 2 or 3 minutes.
- Step 5: Then let the mixer run at optimum speed (12 rpm) for 10 to 15 minutes.
Caution: Never add extra water to a batch of colored concrete. Any differences in slump in successive batches will result in color variations in the concrete. Never use calcium chlorides or any accelerators.
- Step 1: Place the concrete, then strike it off using recognized methods.
- Step 2: Once the concrete has been struck off, use a vibrating screed or a magnesium float. Take care to work in one direction.
- Step 3: Waiting period (do not allow the concrete to get too hard). Allow sufficient time for the concrete to set; rushing the other steps can alter the final appearance of the concrete.
- Step 4: Initial floating should be halted if there is any bleed water on the surface of the concrete (bleed water can result in scaling). Floating can be continued once the bleed water has evaporated. Stamping is the next step, if it is to be carried out.
- Step 5: A power trowel or magnesium hand float can be used for a smooth finish, but over-working the surface will cause discoloration.
Caution: Never fog the surface of the concrete with water; never wet the tools during use. The use of water will result in discoloration and may even damage the surface of the concrete.
