Aggregate-Cement Ratio

• For constant water-content ratio, an increase in

the aggregate-cement ratio will decrease

workability

• Lower aggregate-cement ratio will increase

workability

• If the ratio of volume of coarse to fine

aggregate is high, it will lower the workability

and cause segregation

• Lack in fine aggregate used would results in a

harsh mix that has low workability
