Portland slag and composites cement concretes: engineering and durability properties

The loss of workability in all mixes was of a uniform nature and was found to be more for CEM V/B concrete mixes. Studies of hardened concrete properties, comprising bulk engineering properties (compressive cube and cylinder strength, flexural strength, drying shrinkage) and durability (initial surface absorption, carbonation rates) showed enhanced performance for Portland-slag and composite cement concrete mixes of equivalent strength, except resistance to carbonation.
