Product description
Rebar, also known as reinforcing steel, is an essential component in construction, commonly used in bridges, buildings, skyscrapers, homes, warehouses, and foundations to enhance the strength of concrete structures. Uncoated reinforcement bars (coiled, spooled, straight; deformed or smooth) primary function is to reinforce concrete, which is naturally weak in tension, by leveraging the tensile and compressive strength of steel, as defined by the Concrete Reinforcing Steel Institute (CRSI).
The rebar can be fabricated in CMC fabrication shops where it is cut and bent per customer request and assembled of specific pieces of rebar for installation in a concrete structure. Rebar is fabricated at a number of fabrication facilities. In order to represent the fabrication process, three representative facilities were averaged and used as a proxy for fabrication.
Interpretation
For unfabricated rebar products, the impact assessment results indicate that Module A1, i.e. raw materials, is the key contributor to environmental impact categories for ozone depletion potential. Module A2, i.e. transport to the mill, is not the most significant contributor to any impact category. Module A3, i.e. manufacturing at the mill, is the key contributor to global warming potential, acidification potential, smog formation potential, eutrophication potential, and abiotic resource depletion potential of fossil energy resources.
For fabricated rebar products, the impact assessment results indicate Module A1, i.e. raw materials including unfabricated steel product, is the key contributor to environmental impact categories including global warming potential, acidification potential, smog formation potential, eutrophication potential, and abiotic resource depletion potential of fossil energy resources. Module A2, i.e. transport to the fabrication facility, is not the most significant contributor to any impact category. Module A3, i.e. fabrication, is the key contributor to ozone depletion potential.
The interpretation diagram represents the unfabricated rebar product (without RECs).
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
