ASTM C is used to measure the tensile strength of concrete surfaces. This test method can be used in the concrete construction industry as an indicator of the adequacy of surface preparation before applying a repair or an overlay material.
ASTM C Tensile Testing for Concrete Surfaces
It can also be used to measure bond strength of the material to the substrate. When the test is performed on the surface of a concrete repair or an overlay aztm, it determines the bond strength to the substrate or the tensile strength of either the overlay or substrate, whichever is weaker.
The test specimen is created by drilling a shallow core into and perpendicular to the surface of the substrate, leaving the intact core attached to the concrete. A steel disk should be bonded to the top surface of the test specimen.
Next, a tensile load is applied to the steel disk until a rupture occurs. For testing according to ASTM C, you will need a core drill, core barrel, steel disk and a tensile loading device. For qstm tensile testing machine, you will need a load-indicating system with nominal capacity of 22 kN 5, lbf capable of applying a load at the specified rate.
The loading device should include a tripod or bearing ring for distributing the force to the supporting surface. Next, prepare the specimens according to the official standard. Finally, Record the failure load and the failure mode. C583 a look at our Series which can load to 25 kN 5, lb.
