Hald Cement Data

Description

Heat evolved in setting of cement, as a function of its chemical composition.

Usage

data(cement)

Format

A data frame with 13 observations on the following 5 variables.

x1

percentage weight in clinkers of 3CaO.Al2O3

x2

percentage weight in clinkers of 3CaO.SiO2

x3

percentage weight in clinkers of 4CaO.Al2O3.Fe2O3

x4

percentage weight in clinkers of 2CaO.SiO2

y

heat evolved (calories/gram)
