Detailed Solution for Test: Concrete Technology - 2 - Question 8

The higher the cement aggregate ratio, the leaner is concrete. In lean concrete less quantity of paste is available for providing lubrication, per unit surface area of aggregate and hence the mobility of aggregate is restrained. On the other land in rich concrete mix with lower aggregate cement ratio more paste is available to make the mix cohesive to give better workability.
Workability is also reduced at higher temperature.
