MegaMAx TZ Dry Admixture

There is only one way to make deeper and more vibrant concrete shades to maximize the intensity of all concrete pigments. MegaMAx TZ added with cement at a dosage rate of 1.20% will virtually eliminate efflorescence. Concrete colors will look much darker and vibrant. Excess water must be eliminated when batching. It is this excess water that makes the pigment look lighter and washed out when cured.

MegaMAx TZ is a special blend of proprietary dry ingredients that will also self seal the batch within one hour when blended as instructed. This is very important for Cobalt Blue Pigment which will make the Blue Concrete colors more vibrant once cured.

Adding the correct amount of water will help to chemically convert the cement to dense phase silicates. Adding too much water creates a far higher % of calcium hydroxide, which is soluble, and converts to calcium carbonate which ends up on the concrete surface and causes the haze and efflorescence. A water to cement ratio of 0.32 or lower is important for stronger concrete and making Cobalt Blue Pigment darker and more vibrant.
