Factors Affecting Strength And Workability Of Concrete - …

In the case of rich concrete having lower aggregate cement ratio, more paste is there to make the mix cohesive and this gives better workability. 3. Size of aggregate – As discussed in the strength of concrete that the more the size of aggregate, the less will be the surface area and hence the less amount of water will be required for moisturization.
