concrete splitting tensile strength test

        1. Size of concrete specimens for concrete splitting tensile strength test

Concrete cubic specimen: 150X150X300mm, 100X100X300mm, 200X200X400mm or others

Cylindrical concrete specimen: φ150X300mm, φ100X200mm, φ200X400mm or others

      2. Brief introduction of concrete splitting tensile strength test procedure

1)    Marking:  unless a centering jig is used, two lines shall be marked along which  to apply the load. These lines shall be opposite each other in an axial  plane and the extremities of the two lines shall be connected over each  end of the specimen, to define clearly the plane of loading.

2)    Wipe the concrete specimen, surfaces of jig, packing strips and platens.

3)    Place  the concrete test specimen centrally in the testing machine, optionally  using a jig. Carefully position packing strips and, if required,  loading pieces, along the top and bottom of the plane of loading of the  specimen. Ensure that the upper platen is parallel with the lower platen  during loading.

4)    Select  a constant rate of loading. Apply the load without chock and increase  continuously until break and record the breaking load.
