SANAS T1018
Public test guide
Estimates the tensile resistance of a cylindrical concrete core by loading it across its diameter.
Plain-language explanation
The project specification controls the exact method and acceptance requirement.
A prepared core is placed horizontally between loading strips and compressed until it splits.
Prepared concrete core, loading strips, dimensional tools and calibrated compression machine.
Indirect tensile or splitting strength from failure load and specimen dimensions.
Supports investigation of cracking resistance and the tensile behaviour of concrete taken directly from a structure.
Typical test sequence
Prepare, inspect and measure the core
Align it horizontally with the loading strips
Load to splitting failure and calculate indirect tensile strength
