Friction Transfer test methods as an innovative test method is investigated in different situations and its inherent significant properties and ease of usage is going to be focused on in this paper. Estimation of concrete strength is generally accomplished by testing of cubic or cylindrical specimens that are usually cured under conditions different from the in situ curing conditions. Accurate estimation of concrete strength usually differs from the cubic or cylindrical specimen strength and this is due to several discrepancies: different heat transfer in concrete mass and in discrete specimens, different vibration quality and its effectiveness, humidity of laboratory and site condition and many more. Effectiveness of friction transfer method has been investigated in the past and used in different situations. This paper is going to clarify the detailed properties of this method and the achieved results and also its usage as two separate categories which include testing of concrete strength and testing of bond strength between repaired layers of concrete. In both usages, friction transfer test method showed a better correlation in comparison to other in situ test methods as well as its enhanced flexibility and ease of application.
