A Review of Experimental Results about In Situ Concrete Strength
Abstract:
In this paper, experimental results on the in situ concrete strength have been reported in order to suggest some possible improvements of the current investigation planning strategies. The results of experimental campaign carried out on existing structures are discussed in order to investigate the variability of Destructive Tests (DTs) and Non Destructive Tests (NDTs). Then, the characteristics of the most usual procedures (core testing, rebound number, ultrasonic pulse, ...) have been examined. The results showed primarily the unsuitability (thus its uselessness) of the rebound test in order to describe the variability of concrete characteristics inside the buildings. On this basis, an alternative procedure has been suggested to obtain in-situ concrete strength.
