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

Abstract

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 calls for a significant quantity of raw materials, a longer time to prepare the samples, and expensive machinery. Thus, to evaluate compressive strength, non-destructive testing is preferred. Therefore, the objective of this research is to develop an artificial neural network model based on the results of destructive and non-destructive tests to assess the compressive strength of geopolymer concrete without needing further destructive tests. According to the artificial neural network analysis developed in this study, the compressive strength of geopolymer concrete can be predicted rather accurately by combining the results of the non-destructive with R 2 of 0.9286.

Artificial neural network evaluation of concrete performance exposed to elevated temperature with destructive–non-destructive tests

“…Estimation of concrete compressive strength is made by using the results obtained with different test methods in determining concrete compressive strength [5,13]. Regarding prediction, some studies in the literature have also used artificial intelligence methods to determine concrete compressive strength.…”

“…In a different concrete compressive strength prediction study using compressive strength data taken from concrete samples cured for 7 and 28 days, comparison was made using artificial neural network, decision tree, support vector machine and linear regression [29]. The artificial neural network method was also used to estimate the compressive strength of concrete exposed to high temperatures [5].…”

Experimental and Numerical Assessment of Bonding Between Geopolymer Concrete and CFRP Sheet Using NSM Techniques

“…Recently, geopolymers has been developed as an alternative to traditional ordinary portland cement to produce the geopolymer concrete to reduce the effect of global warming due to cement production process. and many research has been conducted to evaluate the behaviour of gyopolymer concrete for structural applications [14][15][16][17]. Geopolymer morter has also been used with fibre textile grids for strengthening of concrete structure [18].…”
