As you see that there is water reduced as we decrease the water-cement ratio. It is a fact that water reduced in concrete increases its strength. But there is some limit to the water-cement ratio. The minimum water-cement ratio is 0.30 to 0.35, beyond this concrete becomes too stiff and impractical to handle. Featured Image Courtesy. Read More:
