Experiment on Water Absorbing and Surface Pore Property of Concrete

AbstractIn the purpose of finding the relationship between the pore property and water absorbing property of concrete of different strength, scanning electron microscope (SEM for shot) is used to observe the pore in the concrete as well as computer software is used to gain the box counting dimension, water absorbing experiment is also done to the concrete to figure out the water absorbing curve. It's found that the water absorbing property has nothing to do with the strength of concrete; C30 concrete has the lowest box counting dimension and poorest ability absorbing water among the concrete C20, C30 and C40
