on
the design variables, and mi are the measurements for the total number
of construction units r. Note that concrete unit emissions were determined
from each mix design. The emissions from the production of cement,
aggregate, and water were obtained from the database BEDEC
[14]. The plasticizer [39] and superplasticizer [40] were taken from the
European Federation of Concrete Admixtures Associations. Regarding
the silica fume, this study considers that a waste product does not produce
emissions [41]. The beam concrete emissions include the use of
