Factors Affecting the Workability of Concrete. Followings are the factors affect the workability of concrete. Water Content; Hence an optimum water-cement ratio has to be maintained to balance workability and strength of concrete. Mix Proportions. Rich concrete mix Well-graded aggregates tend to fill up voids and easily get workability.
faces of concrete with relatively high compressive strength (above 4, 000 psi). It appears, therefore, that other factors must be considered as affecting abrasion resistance, and compressive strength alone cannot be used as a criterion for durable concrete. Concrete surfaces with poor durability have been a problem on some highways in
