PDF Structural Concrete Practice

(W/C RATIO) The ratio by weight (kg.) between Water and Cement of the fresh mix concrete. The range W/C normal from 0.3 to 0.7. Too much water cannot be totally absorbed by cement of the concrete, it will produce voids in it, and decrease the strength. We can adjust quantity of water into concrete by this range to make the concrete workable.
