concrete: Concrete Compressive Strength Data

In fastR: Foundations and Applications of Statistics Using R

Description

These data were collected by I-Cheng Yeh to determine how the compressive strength of concrete is related to its ingredients (cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, and fine aggregate) and age.

Format

concreteAll is a data frame with the following 9 variables.

• cement amount of cement (kg/m^3)

• slag amount of blast furnace slag (kg/m^3)

• ash amount of fly ash(kg/m^3)

• water amount of water (kg/m^3)

• superP amount of superplasticizer (kg/m^3)

• coarseAg amount of coarse aggregate (kg/m^3)

• fineAg amount of fine aggregate (kg/m^3)

• age age of concrete in days

• strength compressive strength measured in MPa

concrete28 is a subset of concreteAll.

Data were obtained from the Machine Learning Repository (http://archive.ics.uci.edu/ml/) where they were deposited by I-Cheng Yeh (icyeh at chu.edu.tw) who retains the copyright for these data.
