Indian Concrete Journal - ICJSummary: The basic objective of any cement composite is to achieve high strength and improve durability to withstand a longer life span. The present work discusses, the behavior of cement composite with the replacement of cement by an ultrafine material called Alccofine (1203) at 0, 5, 10, 15, 20 % and ground granulated blast-furnace slag (GGBS) at 30 % for M60 grade of concrete. A constant water cement ratio of 0.3 is adopted, to enrich workability a super plasticizer is used. For casting and curing normal procedures are followed as per IS code. To access the mechanical properties, strength and durability tests are conducted on concrete specimens. The strength aspect is maximum at 15 % Alccofine and 30 % GGBS replacement. From the water permeability test it is concluded that there is no seepage of water in all mixes. Hence the concrete is highly durable by the addition of Alccofine. As per ASTM C1202[1], the chloride permeability is very low in all the mixes.
