LIFE CYCLE THINKING | worldsteel
A life cycle assessment (LCA) of a steel product looks at resources, energy and emissions, from the steel production stage to its end-of-life stage, including recycling. The life cycle of steel Life cycle thinking: key to every aspect of sustainabiltity. Life cycle thinking is key to every aspect of sustainability.
Slag Cement and Life Cycle Prediction Models
A life cycle cost computer model (ACI Life 365)1, developed in cooperation with the American Concrete Institutes Strategic Development Council, can be used to evaluate the beneficial effect slag cement has on structural durability. It predicts the time to corrosion onset, time for corrosion to reach an unacceptable level, determines a repair ...

CONCRETE SUSTAINABILITY REPORT
What is Life Cycle Assessment? Life cycle assessment, or LCA, is the investigation and evaluation of the environmental impacts of a product, process or service. LCA evaluates all stages of a product’s life and considers each stage interdependently, meaning that one operation leads to the next. There are several life cycle stages for a given system or process.
