Abstract
This paper presents the test
results on autogenous shrinkage of
high performance concrete containing
various fibers or low shrinkage cement
as an attempt to reduce shrinkage
induced restrained cracking at early
age. Restrained cracking at early age
of conventional concrete are mainly
due to improper curing or plastic
shrinkage and may be avoided by
quality workmanship. However, the
autogenous shrinkage in high strength
concrete or high performance concrete
is inevitable even good curing process
has been taken after placing. In this
investigation, steel fibers and
polypropylene fiber were introduced
to concrete mix so as to reduce the
autogenous shrinkage. Besides,
Aluminate-base low shrinkage cement
was used to replace part of Portland
cement. The main results and findings
are summarized based on the tests of
autogenous shrinkage measurements.
