Radical Concrete Technology. Edited by R K Dhir and P C Hewlett. Published in 1996 by E & FN Spon, 2-6 Boundary Row, London SE1 8HN, UK. ISBN 0 419 21480 1. ABSTRACT. Compressive strength, shrinkage and creep of water-cured and steamcured concrete with and without slags have been compared. Two slag replacement levels of 50 and 70% using slags from two countries (U.K. and South Africa). Creep was measured under a stress of 0.2 of the creep cylinder strength at the age of 14 days for water-cured concretes and 1 day for steam-cured concretes. The influence of steamcuring is to reduce long-term strength, ultimate drying shrinkage, basic and total creep of all types of concrete and to increase short-term strength. The ultimate drying shrinkage of steam-cured slag concretes were similar to or lower than that of PC concrete. For steam cured concrete, the effect of replacement of Portland cement by slag is to decrease the ultimate basic and total creep. Keywords: Compressive strength, Shrinkage, Basic creep, Total creep, Slags, Steamcuring, Water-curing.
