In this study, the experiment was carried out to investigate and analyze the influence of unit water variation on the properties of concrete using meta-kaolin. The main experimental variables were water/binder ratio 30, 40, 50(%), water content 165, 170, 175(kg/㎥) and replacement ratio of meta-kaolin 0, 10, 20, 30(%).
According to the test results, the principle conclusions are summarized as follows.
1) The consistency of meta-kaolin mixed concrete tends to differ with compactability of fresh concrete according to unit weight in W/B ratio.
2) The air content of meta-kaolin mixed concrete tends to be unrelated with unit weight variation.
3) The compressive strength of meta-kaolin mixed concrete tends to increase, as the unit weight increases.
4) The stress-deformation curve of meta-kaolin mixed concrete tends to create rather high elastic coefficient, excepting unit weight 170㎏/㎥ in W/B 30%.
