Prediction of Geopolymer Concrete Compressive Strength Utilizing Artificial Neural Network and Nondestructive Testing

open access: yesCivil and Environmental Engineering, 2022
A promising substitute for regular concrete is geopolymer concrete. Engineering mechanical parameters of geopolymer concrete, including compressive strength, are frequently measured in the laboratory or in-situ via experimental destructive tests, which ...

Applying Artificial Intelligence to Improve On-Site Non-Destructive Concrete Compressive Strength Tests

open access: yesCrystals, 2021
In the construction industry, non–destructive testing (NDT) methods are often used in the field to inspect the compressive strength of concrete. NDT methods do not cause damage to the existing structure and are relatively economical.

Research on the Rebound Hammer Testing of High-Strength Concrete’s Compressive Strength in the Xinjiang Region

open access: yesBuildings, 2023
Enhancing the assessment of compressive strength and the efficiency of rebound hammers in non-destructive testing for high-strength concrete is an urgent issue in construction engineering. This study involved C50 to C90 high-strength concrete specimens, utilizing rebound hammers with nominal energies of 4.5 J and 5.5 J, along with a compression machine.

A Comparative Analysis of the Rebound Hammer and Pullout as Non-Destructive Method in Testing Concrete

open access: yesEuropean Journal of Engineering Research and Science, 2020
A comparative analysis between Rebound Hammer and Pullout method in testing concrete was conducted in this study. Experimental analysis were carried out to compare the correctness between the two testing method in estimating the strength of concrete. Different cube (cubes of 175 x 175 x 175) samples were prepared using two mix designs of 1:2:4 and 1:3 ...
