Life Cycle Inventory Of Slag Cement Concrete
The LCI includes materials, energy, and emissions from extraction of raw materials through the manufacture of one cubic yard of concrete.
Five concretes with different performance criteria were considered: 20 and 35 MPa (3000 and 5000 psi) ready mixed concrete, 50 and 70 MPa (7500 and 10,000 psi) precast concrete, and a concrete block mix. The LCI was determined for three combinations of cement for each concrete performance criteria: 100 percent portland cement, and 35 and 50 percent substitution of slag cement for the portland.
