Portland Cement Dataset
These data come from an experiment investigation of the heat evolved during the setting and hardening of Portland cements of varied composition and the dependence of this heat on the percentages of four components in the clinkers from which the cement was produced.
A data frame with 13 observations on the following 5 variables.
- The heat evolved after 180 days of caring. (Calories per gram)
- Tricalcium Aluminate.
- Tricalcium Silicate.
- Tetracalcium Aluminoferrite.
- $\beta$ Dicalcium Silicate.
