Read More4. Compressive Strength of Concrete The strength of concrete is controlled by the proportioning of cement coarse and fine aggregates water and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength as shown in Fig.1. The lower the watercement ratio the higher is the compressive strength.

Sawdust was used to replace sand at percentages of 25 50 75 and 100 by volume. A water cement ratio of 0.55 was adopted. Concrete was produced by mixing the constituent raw materials in an electric concrete mixer.

Read MoreConcrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness. 1011 In a concrete having a watercement ratio lower than 0.42 hydration stops when there is no more water to hydrate the cement particles. Below this critical value of 0.42 very fine cement particles can be fully hydrated but only the surface of the coarsest ones
Read More20191123Concrete has relatively high compressive strength it doesnt crack under weight but significantly lower tensile strength it cracks when being pulled. The compressive strength is typically controlled with the ratio of water to cement when forming the concrete and tensile strength is increased by additives typically steel to create reinforced concrete.
