ABSTRACT
This paper is concerned with the durability of concrete made with cements that are currently available in the UK, as follows:
Type I Portland cement Type II/A-V Portland Fly Ash cement (fly ash content 6-20% by mass) Type II/B-V Portland Fly Ash cement (fly ash content 21-35% by mass) Type Il/A-S Portland Slag cement (slag content 6-20% by mass) Type II/B-S Portland Slag cement (slag content 21-35% by mass) Type III/A Blastfurnace cement (slag content 36-65% by mass) Type III/B Blastfurnave cement (slag content 66-80% by mass) Type lll/C Blastfurnace cement (slag content 81-95% by mass)) Type II/A-D Portland Silica Fume cement (silica fume content 6-10% by mass)
It has not been possible to establish what the effect of limestone filler is on the results reported but it may be possible to infer the results from Dr Matthews’ paper reported in these Proceedings. The portland cement grade used throughout corresponds to 42.5N to BS 12 (1992) and again it has not been possible to identify whether similar durability performance would be achieved with the higher grade of 52.5 (the 32.5 grade is not available in the UK and, in any case, is likely only to be manufactured as a Type II CEM cement).
