concrete: Concrete Slump Test Data

In TFM: Sparse Online Principal Component for Truncated Factor Model

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

data(concrete)

Format

A data frame with 103 rows and 11 columns.

V1

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

V2

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

V3

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

V4

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

V5

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

V6

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

V7

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

V8

Slump of the concrete (cm).

V9

Flow of the concrete (cm).

V10

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

V11

Additional variable (if applicable).

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.
