Sand Calculation Formula:
From: | To: |
This calculator determines the amount of sand needed for concrete base layers (e.g., bedding). Proper sand quantity is essential for creating a stable foundation for concrete work.
The calculator uses the formula:
Where:
Explanation: The calculation accounts for the volume of sand needed and converts it to weight using the material density.
Details: Accurate sand calculation ensures proper concrete bedding, prevents material waste, and helps with project cost estimation.
Tips: Enter area in square meters, depth in meters (typically 3-5 cm), and sand density (1600 kg/m³ is default). All values must be positive numbers.
Q1: What's the typical depth for concrete base sand?
A: Usually 3-5 cm (0.03-0.05 m) for most residential concrete projects.
Q2: Does sand type affect the density?
A: Yes, dry loose sand averages 1442 kg/m³ while wet packed sand can be 1682 kg/m³. 1600 kg/m³ is a good average.
Q3: How do I convert from kg to cubic meters?
A: Divide the weight by density (e.g., 1000 kg ÷ 1600 kg/m³ = 0.625 m³).
Q4: Should I add extra for compaction?
A: The calculation assumes compacted sand. For uncompacted sand, increase depth by 20-30%.
Q5: What about sand for mortar or concrete mix?
A: This calculator is for bedding sand only. Mortar/concrete sand calculations are different.
