· Using NonDestructive Testing To Determine The Compressive Strength Of Concrete Nondestructive concrete testing is one of the methods to assess the compressive strength of concrete in a constructed building. Since nondestructive testing yields data immediately, builders can determine critical structural characteristics of a building in realtime.
predict the compressive strength of the high performance concrete by using classifiion algorithms like Multilayer Perceptron, M5P Tree models and Linear Regression. The result from this study suggests that tree based models perform remarkably well in predicting .

Compressive Strength of Concrete. The compressive strength test results for M30 and M60 grades of concrete are shown in Table 3 for both 14 and 28 days of curing. In the case of M30 grade it is seen that the compressive strength initially increases reaches a peak at 1 fibre content and later reduces for both 14 and 28 days of curing. Chat Online
