ASTM C78/C78M Flexural Strength of Concrete Testing
ASTM C78 is the test method for the flexural strength of concrete using a simple beam with third-point loading. To match this to your program, talk with our team.
What ASTM C78 Covers
It determines the flexural strength (modulus of rupture) of a concrete beam, an important property for pavements and slabs that carry bending loads.
How the Test Is Run
A concrete beam is supported near its ends and loaded at the third points until it fractures, and the modulus of rupture is calculated from the peak load and beam dimensions.
Why It Matters
Flexural strength governs concrete pavement and slab design; a stiff loading frame with third-point fixturing and a controlled rate is required.
