concrete: Concrete Slump Test Data

In LFM: Laplace Factor Model Analysis and Evaluation

Concrete Slump Test Data

Description

This dataset contains measurements related to the slump test of concrete, including input variables (concrete ingredients) and output variables (slump, flow, and compressive strength).

Usage

concrete

Format

A data frame with 103 rows and 10 columns.

• Cement: Amount of cement (kg in one M^3 concrete).

• Slag: Amount of slag (kg in one M^3 concrete).

• Fly_ash: Amount of fly ash (kg in one M^3 concrete).

• Water: Amount of water (kg in one M^3 concrete).

• SP: Amount of superplasticizer (kg in one M^3 concrete).

• Coarse_Aggr: Amount of coarse aggregate (kg in one M^3 concrete).

• Fine_Aggr: Amount of fine aggregate (kg in one M^3 concrete).

• SLUMP: Slump of the concrete (cm).

• FLOW: Flow of the concrete (cm).

• Compressive_Strength: 28-day compressive strength of the concrete (MPa).

Details

The dataset includes 7 input variables (concrete ingredients) and 3 output variables (slump, flow, and compressive strength). The initial dataset had 78 data points, with an additional 25 data points added later.

Note

The dataset assumes that all measurements are accurate and does not account for measurement errors. The slump flow of concrete is influenced by multiple factors, including water content and other ingredients.
