The Raw Materials Of Concrete Hollow Block

The cement slurry shrinks fast, and the stone gravel acts to inhibit shrinkage and stabilize the volume. Play the role of the skeleton. The sand fills the voids of the stones, and the cement fills the voids of the sand to form a dense pile. "Gravel" The concrete mixture acts as a cohesive and water-retaining agent.

Concrete Mix Design Manual Rev08

hydration of cement and water form a stone-like mass called paste. When the paste is intermixed with aggregates, (sand, gravel, crushed stone or other granular material), it acts as an adhesive and binds the aggregates together to form concrete. The hydration begins immediately upon the water and cement coming in contact with each other and

Concrete: The Basic Mix

A basic mixture of mortar can be made using the volume proportions of 1 water : 2 cement : 3 sand. Most of the student activities can be conducted using this basic mixture. Another old rule of thumb for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable.
