Do you often run out of materials mid-project or overpay for excess supplies? Accurate material calculation is the first step to a successful project. In this guide, we'll show you how to calculate quantities for steel, cement, bricks, and more – with free tools that save 80% of your time!"*
1. The Basics: What You Need to Calculate
-
Concrete: (Slabs, foundations, columns)
-
Steel: (Footings, beams, slabs)
-
Bricks/Blocks: (Walls, fences)
-
Secondary Materials: (Sand, nails, wires)
2. Calculation Methods (With Practical Examples)
A. Concrete Calculation
Formula:
Volume = Length × Width × Height
Example:
For a 150 m² slab at 0.15m thickness:
150 × 0.15 = 22.5 m³
Free Tool:
Concrete Calculator by Calculator.net
B. Steel Reinforcement Calculation
Rule of Thumb:
-
80-100 kg steel per 1 m³ concrete for foundations
-
120-150 kg steel per 1 m³ concrete for columns
Example:
For 30 m³ of column concrete:
30 × 130 = 3,900 kg (3.9 tons)
C. Brick/Block Calculation
Formula:
Number of Bricks = (Wall Area in m²) × (60 bricks per m² for 20cm-thick walls)
Example:
For a 100 m² wall:
100 × 60 = 6,000 bricks
