Understanding the Unit
Weight of Concrete: A Guide for Project Managers and Civil Engineers
All the
materials used for building and construction, concrete is one of the most
commonly applied. Hence, its unit weight is crucial in any building-related
computation. The unit weight of concrete varies and is mix design-dependent,
where most concretes are a mixture of Portland cement, sand, coarse aggregates,
and water. Below are typical values and conversion factors for the unit weight
of concrete in different units.
What is
the Unit Weight of Concrete in Kilograms per Cubic Meter (kg/m³)?
- Plain Cement Concrete (PCC): The typical unit weight of
PCC is around 2,400 kg/m³.
- Reinforced Cement Concrete
(RCC): The
typical unit weight of RCC is around 2,500 kg/m³.
What is
the Unit Weight of Concrete in Pounds per Cubic Foot (lbs/ft³)?
- PCC (dry mix): Unit weight of PCC in its dry
mix condition is approximately 133 lbs/ft³.
- PCC (wet mix): The fresh PCC unit weight is
typically about 150 lbs/ft³.
- RCC: The unit weight of RCC is
generally around 156 lbs/ft³.
What is
the Unit Weight of Concrete in Kilonewtons per Cubic Meter (kN/m³)?
- PCC: The typical unit weight of
PCC is about 24 kN/m³.
- RCC: The typical unit weight of
RCC is about 25 kN/m³.
What is
the Unit Weight of Concrete in Pounds per Cubic Inch (lbs/in³)?
- PCC: The unit weight of PCC is
approximately 0.0867 lbs/in³.
- RCC: The unit weight of RCC is
approximately around 0.0903 lbs/in³.
What is
the Unit Weight of Concrete in Kilograms per Cubic Foot (kg/ft³)?
- PCC: The typical unit weight of
PCC is about 68 kg/ft³.
- RCC: The typical unit weight of
RCC is about 71 kg/ft³.
What is
the Unit Weight of Concrete in Kilograms per Cubic Centimeter (kg/cm³)?
- PCC: The unit weight of PCC is
about 0.0024 kg/cm³.
- RCC: The unit weight of RCC is
approximately about 0.0025 kg/cm³.
What is
the Density of Concrete in Different Units?
- 1 Cubic Yard of Concrete: A typical cubic yard of concrete
weighs approximately 4,050 lbs.
- Density: Ready
mix concrete mixture density is typically 2,400 kg/m³, 150 lbs/ft³, or 24
kN/m³.
What
are the Conversion Factors for Concrete Density?
- 1 kg/m³ = 0.0624 lbs/ft³
- 1 lbs/ft³ = 16.018 kg/m³
- 1 kN/m³ = 101.97 lbs/ft³
- 1 lbs/in³ = 27,680 lbs/ft³
