Concrete and Slag Cement: Heidelberg Materials

The Advanced Nuclear Material Research Center (ANMRC) project is a first of its kind Nuclear Laboratory in Canada. The project is being built in accordance with CSA N299 and N287.5 standards. Slag cement was used in controlled low strength material (CLSM) backfill placed between bedrock and raft slab foundations (approximately 10 m [33 ft] deep). The engineering team required that the CLSM strength was between 2 to 5 MPa (435 to 725 psi) at 28 days; an exceptionally narrow strength requirement.
