Compressive Strength of Concrete Hollow Blocks (Formula

Nov 16, 2017· Hello! My group mates and I are working on a project concerning potential reinforced concrete hollow blocks using junk shop materials We're pretty new to the entire process, and we're not sure of how we will arrive to our results (if the final results will be declared via machine or derived through a certain formula).

Compressive Strength

The relationship between compressive strength and age of the AACM concrete cured in air (20°C, 60 RH) is plotted in Fig 181 for two compositions with different aggregate grading and content The compressive strength under wet curing can be somewhat lower but occasionally it is higher.

Strength of concrete

Strength of concrete Q Is compressive strength the only strength factor of interest? A No, in the early development of concrete, compressive strength was the primary interest and it became the natural basis for recording the results of experience and research.

Reinforced Concrete Design

Since concrete is a brittle material and is strong in compression It is weak in tension, so steel is used inside concrete for strengthening and reinforcing the tensile strength of concrete The steel must have appropriate deformations to provide strong bonds and interlocking of both materials.

Compressive strength test

Compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.
