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.
