Concrete mixture strength learning tool

Designing the right concrete mixture is a complex process of balancing many variables.

This application helps civil engineering students to explore the impact of concrete mixture decisions on compression strength based on five variables:

• Curing time [days]
• Water content [l/m^3]
• Cement content [kg/m^3]
• Fine aggregate [kg/m^3]
• Coarse Aggregate [kg/m^3]

Students choose their concrete mixture and curing age, after which the application shows the predicted strength and a decision tree.

The application assists beginning engineering students to understand the relationships between the five variables and concrete strength.

The application uses a Regression Tree, based on data published by Yeh (1998).

A decision tree emulates the types of decisions made by engineers when designing concrete mixtures.

The application is great tool to provide students a first introduction into the decisions that guide good concrete mixture design.
