To Determine The Tensile Strength And Compressive Strength Of Cement

Tensile Strength of Concrete

A limiting factor in the safety of mass concrete structures, such as concrete arch dams under seismic loadings, is the tensile strength of the concrete. Tensile strength can be tested three ways: direct tension, splitting tension, and flexural tests. Results of these tests differ, and results of tests made on cores taken in the field differ from results made on laboratory specimens. Some ...

Compressive and Tensile Strength of Concrete: Relation ...

The ratio of tensile strength to compressive strength depends upon the strength of concrete. Thus higher the compressive strength, higher the tensile strength, but the rate of increase of tensile strength is of decreasing order. The tensile strength of concrete is more sensitive to improper curing than the compressive strength.

Hardened Concrete - Strength

Although the tensile strength of concrete is not importer from the load-bearing point of view, it is significant for judging cracking potential of concrete in various situations. Generally, the tensile strength is only 1/10 to 1/7 of the compressive strength. Three methods are commonly used to determine the tensile properties: Direct tension, Split tension, and Flexure.
