Fresh Concrete: Workability

Fresh Concrete: Workability

The higher the aggregate/cement ratio, 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 hand, in case of rich concrete with lower aggregate/cement ratio, more paste is available to make the
