Fig. 4 (e) represents the effect of different water-cement ratios on the rebound quality and the compressive strength of concrete. The rebound value and the compressive strength of concrete enhanced with the reduction of the water-cement ratio at the same age. The trend line shows a good correlation between rebound index and compressive strength.
An extensive comparative analysis of computational intelligence approaches aimed at predicting the compressive strength (CS) of concrete using two non-destructive testing methods: the rebound hammer (RH) and the ultrasonic pulse velocity (UPV) test. This study conducts an extensive comparative analysis of computational intelligence approaches aimed at predicting .There are two methods for finding compressive strength of concrete - Destructive testing method and Non-destructive testing method. The standard method of evaluating the quality of concrete in buildings or structures is to test specimens cast simultaneously for compressive, flexural and tensile strengths (Feldman, 1977) [1].@article{AliBenyahia2023AnalysisOT, title={Analysis of the Accuracy of In-Situ Concrete Characteristic Compressive Strength Assessment in Real Structures Using Destructive and Non-Destructive Testing Methods}, author={Khoudja Ali-Benyahia and Said Kenai and Mohamed Ghrici and Zoubir Mehdi Sbarta{\"i} and Sidi Mohammed Elachachi}, journal={SSRN .5 Concrete Strength Testing Methods – Non-Destructive. . Concrete Compressive Strength. Whether assessing older concrete or examining reasons for recently failed laboratory tests, in-place compressive strength is the most common factor for consideration. Evaluation of concrete strength can take a couple of different directions.
The use of the non-destructive testing method for determining the compressive strength of high performance concrete ensures high quality. Non-destructive techniques such as the Proceq SilverSchmidt BN hammer are suited to this applications. This case study describes how Hyundai E&C use it.
Destructive testing for compressive strength is comprised of creating a cube of cement, curing it at well temperature and pressure conditions, and then crushing the cube, measuring the force required to break the cube. This is a destructive test because the force is increased until the cement fails in compression. . API Recommended Practice .

compressive strength of a cement slurry; destructive and non-destructive. The destructive method involves preparing a slurry in a mold and allowing the cement to cure under temperature and pressure for a specified amount of time. After this time has elapsed, the sample is put in a press and crushed.There are many test methods to assess concrete in sit u, such us Non-destructive Tests methods (Schmidt Hammer and Ultrasonic Pulse Velocity), and these meth ods consider indirect and predicted tests to determine concrete strength in situ, whereas these tests affected by many parameters depend on the nature of materials used in production concrete. So, there is a .
By Kaushal Kishore Materials Engineer, Roorkee INTRODUCTION The standard method of determining strength of hardened concrete consists of testing concrete cubes in compression. The quality of entire concrete of a structure cannot be fully assessed by testing a few concrete cubes. The results obtained in testing cubes do not always reflect the actual .

RN test as a non-destructive test can predict the compressive strength of concrete specimens with more accuracy. The results showed that the accuracy prediction of the sole RN is increased by aging (R 2 = 0.801, R 2 = 0.868 and R 2 = 0.916 for the age of 7 days, 28 days and 90 days, respectively).The pin penetration test has been introduced as a new NDT test method in Japan. This tester consists of a spring loaded hammer that drives a steel pin into the concrete surface, which leaves a crater. In order to accept this test as one of the non- destructive test methods, it is necessary to ensure the accuracy of measurement of crater depth used to estimate the compressive .
Non destructive testing of concrete is a method to assess properties and strength of concrete in existing structures without causing damage. Learn methods and uses . A 0.25 in. (6.5 mm) diameter probe, driven by a precision powder charge, gauges concrete's compressive strength based on penetration depth. While calibration charts are provided .
In this paper, the non-destructive testing methods are analyzed in view of their usability in evalulation of the interlocking paving blocks’ compressive strength.
