Q: Concrete with bulk density 2400 kg/m³ is:
  • A. Extra light weight concrete
  • B. Dense weight concrete
  • C. Super heavy weight concrete
  • D. Light weight concrete
Correct Answer: Option B - • The density of light-weighted concrete is about 1900 kg/m³ • The density of dense-weight concrete is about 2400kg/m³. • For concrete to be termed as high density concrete it. most have a unit weight ranging from about 3360 kg/m³ to 3840 kg/m³, which is about 50% higher than the weight of conventional concrete.
B. • The density of light-weighted concrete is about 1900 kg/m³ • The density of dense-weight concrete is about 2400kg/m³. • For concrete to be termed as high density concrete it. most have a unit weight ranging from about 3360 kg/m³ to 3840 kg/m³, which is about 50% higher than the weight of conventional concrete.

Explanations:
