The shrinkage of mixtures containing replacements of total aggregate
with prewetted lightweight aggregate (LWA) (0, 8, and 10% by
volume) and replacements of cement with Grade 100 slag cement
(0 and 30% by volume) and silica fume (0, 3, and 6% by volume)
is evaluated. The results show that internal curing provided by
prewetted LWA reduces the tendency of the mixtures to develop
shrinkage strains. Further reductions are observed as slag is added
in conjunction with prewetted LWA and as silica fume is added in
conjunction with the prewetted LWA and slag.
