Compressive Strength of Concrete Cubes

Compressive Strength of Concrete Cubes

According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. Why do we test at 7, 14 28 days? Concrete is a macro content with Sand, Cement, Coarse aggregate as its microingredient (Mix Ratio) and gains its 100% strength over time at the hardened state.

A MATHEMATICAL MODEL FOR PREDICTION OF THE STRENGTH .

Although the blocks are preferred to other similar walling material such as bricks and concrete blocks due to the availability of the dominant material (sand) in the country and the ease of manufacture, the material is known to have several drawbacks: it has a low compressive strength which could be a factor for structural failure in buildings.

Concrete Mix Ratios (Cement, Sand, Gravel)

Concrete Mix Ratios (Cement, Sand, Gravel)

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength.

HighStrength Concrete

HighStrength Concrete. In the early 1970s, experts predicted that the practical limit of readymixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch (psi). Over the past two decades, the development of highstrength concrete has enabled builders to easily meet and surpass this estimate.

Concrete blocks

Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cementsand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a onestorey building. The blocks may be solid, cellular or hollow.
