Strength, Water Absorption and Porosity of Concrete ...

Jan 01, 1996  The water absorption for the two series of concrete is shown in Table 5 and Fig. 2. It can be seen in the table that the water absorption, for both series, increases as the W/C ratio increases. The maximum absorption was observed at W/C ratio of 0.55. As the W/C ratio becomes larger than 0.55, water absorption decreases.
