||Pull Out Strength kN
||Relative Compression Strength-psi
Concrete strength is determined by measuring the force in kilo Newton’s (kN) required to pull a 2 x 1 inch plug from the concrete surface. This force is also expressed in the more conventional psi compression strength scale.
The increase in overall strength is very significant in percentage terms and demonstrates how SURTREAT® formulations can increase the surface strength of concrete. It is anticipated that the increase may be even greater in areas along the crack faces, which have become weak and are prime sources of fragments and FOD. SURTREAT® inhibits the formation of FOD by increasing concrete strength.
