Data Type: 
  multivariate

Abstract: 
  Concrete is the most important material in civil engineering. The
  concrete compressive strength is a highly nonlinear function of age and
  ingredients. These ingredients include cement, blast furnace slag, fly ash,
  water, superplasticizer, coarse aggregate, and fine aggregate.

Data Characteristics:
  The actual concrete compressive strength (MPa) for a given mixture under a
  specific age (days) was determined from laboratory. Data is in raw form (not scaled).

Summary Statistics:
  Number of instances (observations): 1030
  Number of Attributes: 9
  Attribute breakdown: 8 quantitative input variables, and 1 quantitative output variable
  Missing Attribute Values: None

Variable Information:
  Given is the variable name, variable type, the measurement unit and a brief description.
  The concrete compressive strength is the regression problem. The order of this listing
  corresponds to the order of numerals along the rows of the database.
