Amcon’s EnviroTrol™ curing system incorporates numerous cycles of high temperature, steam and carbon dioxide (CO2) to aggressively accelerate the hydration process. The incorporation of CO2 into the curing process assists in the carbonation of the units. Carbonation can also cause the units to shrink. Fully carbonating CMU’s in a controlled setting before they are placed in a wall will minimize or eliminate shrinkage cracks. The EnviroTrol system controls the temperature, humidity, and carbon dioxide until the hydration and carbonation processes are functionally complete. The results are architectural units that are dry, color consistent, resistant to carbonation shrinkage, and have a greatly reduced efflorescence potential when compared to conventionally cured CMU’s.
