• Streamline project timelines.
• Enhance structural integrity and safety.

Categories of basic civil engineering formulas

1. Concrete Calculations

• Mix Design Formula:
  
  Used to determine the perfect mix for concrete based on workability and strength.

2. Area and Volume Calculations

• Area of a Rectangle:
  Area = Length×Width
• Volume of a Cylinder:
  Volume = πr²h

3. Slope and Gradient Calculations

• Gradient Formula:
  ​
  Used for road and drainage designs.

4. Earthwork Calculations

• Volume of Excavation:
  

5. Steel Quantity Calculations

• Steel Weight Formula:
  Weight = Length×Area×Density

6. Unit Weight Calculations

• Unit Weight Formula:
  Unit Weight = Weight/Volume

Key Civil Engineering Formulas

Concrete Mix Design

• Water-Cement Ratio:

W/C Ratio=Weight of Water/Weight of Cement

Beam and Column Calculations

• Bending Moment:
  M = wl²/8​ (for a uniformly distributed load).

Retaining Wall Design

• Lateral Earth Pressure:

P=1/2γH²K

Where γ is soil density, H is height, and K is the pressure coefficient.

Foundation Design

• Bearing Capacity:
  

Hydraulic Engineering Formulas

• Flow Rate:
  Q = A×v
  Where A is the area and v is velocity.
