concrete_compressive_strength

Data Description Concrete is the most important material in civil engineering. The concrete compressive strength is a highly nonlinear function of age and ingredients. Each instance represents a description, different features of concrete instance, including its compressive strength. The latter can be predicted using the other features about the concrete. Attribute Description 1. *cement* - amount in kg in a m3 mixture 2. *blast_furnace_slag* - amount in kg in a m3 mixture 3. *fly_ash* - amount in kg in a m3 mixture 4. *water* - amount in kg in a m3 mixture 5. *superplasticizer* - amount in kg in a m3 mixture 6. *coarse_aggregate* - amount in kg in a m3 mixture 7. *fine_aggregate* - amount in kg in a m3 mixture 8. *age* - age in days (1 - 365) 9. *strength* - in MPa, target feature
