INTRODUCTION OF THE CONCEPT OF THE STALE CEMENT RECYCLING DIRECTLY IN THE PROCESS OF CONCRETE PRODUCTION AND CONSERVING RESOURCES
Ordinary Portland cement has limited shelf life, which is usually not more than 6 months, after which it begins deteriorating and losing it activity, which leads to the need to increase the dosage of the “de-activated” cement into concrete, or simply discard it.
INKAS® developed and patented MACROCEMENT™ technology of resurrection of the aged de-activated cement directly in the concrete manufacturing process that allows the production of standard concrete from old sub-standard cement.
The technology of cement renovation makes possible to reduce its environmental impact on the Use Stage of the Life Cycle of cement.
