Formatted abstract

This thesis centres on a series of experiments on the influence of curing and compaction in shrinkage, creep and strength of concrete. Compaction and curing have significant influence on the strength of concrete, as insufficient compaction will produce poor quality concrete, and the immature termination of curing will lead to deterioration of durability. However, the study on the influence of compaction and curing on volume change still have gaps to be filled, and it is our aim to fill in some of the gaps in shrinkage and creep.  

Specimens are cast with different degrees of compaction (100%, 95%, 90%) and lengths of in-mould curing (1 day, 3 days, 7 days). Standard specimens are also prepared, as a comparison to the non-standard specimens, with 100% compaction and standard moist-curing, in accordance in AS1012.  

3 sets of tests on the strength of the specimens are performed, namely compressive strength, modulus of rupture and Young’s modulus. Drying shrinkage specimens are prepared and volume changes are recorded every 7 days for 56 days. The creep specimens are set up in hydraulic rigs and volume changes are recorded every 7 days for 42 days. Based on the results collected, although some inferences are made regarding the influence of compaction and curing on shrinkage and curing, further studies will be needed to achieve a more conclusive statement on these behaviours.
