The water-cement ratio is usually recommended to be between 0.27 and 0.34 [Tennis, 2004]. For cement contents of 250 kg/m3 or less, it proved impossible to mould specimens that were robust enough to test. For this reason, higher cement contents of 300 kg/m3, 350 kg/m3 and 400 kg/m3 were selected for study.
