Context

Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewerage systems, pipelines, structural components of buildings, and railways.

Concrete is the most important material in civil engineering. The concrete compressive strength is a highly nonlinear function of age and ingredients. Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce the size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.

Objective

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. Your objective is to build a machine learning model that would help Civil Engineers to estimate the compressive strength of the concrete and they can further take a decision whether the concrete should be used in their current project or not.

Evaluation Criteria

Submissions are evaluated using Root-Mean-Squared-Error (RMSE).

How do we do it?

Once you generate and submit the target variable predictions on the testing dataset, your submissions will be compared with the true values of the target variable.

The True or Actual values of the target variable are hidden on the DPhi Practice platform so that we can evaluate your model's performance on testing data. Finally, a Root-Mean-Squared-Error (RMSE) for your model will be generated and displayed.
