The Non-destructive tests considered one of the most important solvent of losing cubing test to estimate compressive strength .The objective of research is main to find a relationship between many situations of combined method equations for Non-destructive tests between Ultrasonic Pulse Velocity tests, hammer rebound test. Also for producing a new equation where, the variation and the contrast between the use of the highest values and minimum values is lower than the previous equations. Using of advanced statistical programs such as (SPSS) program as well as program (Mini Tab) makes rustles more confidence. The conclusion equation has experimented with real data for one building, it was found that this equation gives medium rates and formulas used and therefore that the use of this equation gives excellent results and removed the negative consequences of the equations of the other.
