Flexural Testing for Beams

Concrete specimen flexural strength testing is a method of measuring the tensile strength of concrete. In this test measured the amount of concrete specimen resistance or a concrete piece in effect of bending force. This test by applying force to a concrete specimen with the cross section dimensions of 150×150 mm it’s done by a certain length, and loading performed with at least three points. Concrete specimen flexural strength is expressed as the modulus of rupture (Modulus of Rupture (MR)), ASTM C293 (center point loading) is calculated. It’s calculated by the method of testing in the standard ATM C78 (three-point loading) and Standard ASTM C293 (center point loading).

Flexural strength in according to dimensions, volume and of course the material gradation of concrete mixture is approximately 10 up to 20% the compressive strength of the same sample. However, the relationship between flexural strength and compressive strength of concrete and other special materials can be achieved through the accurate testing, would help in achieving concrete mixture design and the structural designing which will be very considerable.

Soil Mechanic Industries of Iran provides the possibility for the machines designed by this company the calculate the amount of concrete specimen Flexural strength with dimensions: 100×100×500, 150×150×750 and 200×200×1000 mm, by applying force or three-point loading or central point loading.
