摘要: Abstract The use of different cementitious main constituents is permitted within the BS EN 197-1 for in concrete construction. selection cement types made depends on requirement enhanced engineering and durability properties as well exploiting potential producing environmentally friendly concretes practical applications. results a laboratory experimental programme aimed at examining performance Portland-slag composite (CEM II/B-S, CEM II/B-M, V/A V/B) mixes designed equivalent 28-day compressive cube strengths 40 50 N/mm 2 are reported paper. effect up to 30–50% ground granulated blast-furnace slag (GGBS) its' combination with silica fume (SF) fly ash (FA) -within limits-on fresh, have been established its suitability range applications was assessed. loss workability all uniform nature found be more V/B mixes. Studies hardened properties, comprising bulk (compressive cylinder strength, flexural drying shrinkage) (initial surface absorption, carbonation rates) showed except resistance carbonation.
