in the cement sector, the use of clinker substitutes to reduce the clinker-to-cement ratio is already common practice, as it is generally less expensive than equipping a kiln with ccus. however, these substitute constituent materials do not negate the need for clinker entirely, and their use is limited by availability (e.g. natural pozzolanas common in certain regions and not found in others).,environmental excellence for responsible growth - cemex,it is used in several stages during the production process of cement, ready-mix and aggregates as well as for cleaning plants, trucks and equipment. to protect this natural resource and help our business flourish, we work to increase our water efficiency and control our water waste.
