Concrete Compressive Strength Prediction using Machine

05-03-2020· We have analysed the Compressive Strength Data and used Machine Learning to Predict the Compressive Strength of Concrete. We have used Linear Regression and its variations, Decision Trees and Random Forests to make predictions and compared their performance. Random Forest Regressor has the lowest RMSE and is a good choice for this problem.

Machine learning-based compressive strength prediction

10-01-2020· On the other hand, with the development of artificial intelligence (AI) in recent years, it is a trend to use machine learning (ML) techniques to predict the concrete compressive strength. ML is a branch of AI, and can be used for several objectives, e.g., classification, regression, clustering, etc. Predicting concrete compressive strength is just one application of the regression function of ML.

Predicting Compressive Strength of Concrete Kaggle

The concrete compressive strength is a highly nonlinear function of age and ingredients .These ingredients include cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, and fine aggregate. The actual concrete compressive strength (MPa) for a given mixture under a specific age (days) was determined from laboratory.

Testing the Compressive Strength of Concrete — What,

The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units.
