#' Concrete Compressive Strength Data

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

Concrete is a subset of ConcreteAll.
