Type and size of coarse aggregate, water-cement ratio, and cement-aggregate ratio thus requires a careful consideration. Malhotra (1976) provides a detailed study on pervious concrete; the researcher showed that compressive strength of pervious concrete depends on water-cement ratio, and on aggregate-cement ratio.
When the weight of cement is more, i.e. aggregate cement ratio is less, the concrete has more cement paste required to coat aggregates and fill the voids between them. This more cement paste makes the concrete relatively easy to mix, place and compact as it reduces the friction between aggregates and allows its smooth movement.
Concrete mix ratio: The strength of concrete mixture depends on the ratio in which these four ingredients are mixed. Concrete mix ratio of 1:3:3 - On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.
