1. What is Angle of Repose?

The angle of repose is the steepest angle at which a material can be piled without sliding. For concrete, this angle is crucial for understanding its behavior in various construction scenarios.

2. How Does the Calculator Work?

The calculator uses the angle of repose formula:

Where:

• \( \theta \) — Angle of repose (degrees)
• \( h \) — Height of the pile (meters)
• \( base \) — Width of the pile base (meters)

Explanation: The formula calculates the angle based on the relationship between the height and base width of a material pile.

3. Importance in Concrete Applications

Details: Understanding the angle of repose is essential for concrete formwork design, slope stability, and material handling in construction projects.

4. Using the Calculator

Tips: Measure the height and base width of your concrete pile accurately. Enter values in meters for precise calculations.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical angle of repose for concrete?
A: Fresh concrete typically has an angle of repose between 30-45 degrees, depending on mix design and moisture content.

Q2: How does aggregate size affect the angle?
A: Larger aggregates generally result in steeper angles due to increased interlocking between particles.

Q3: Why is this important for formwork?
A: Knowing the angle helps design forms that can contain the concrete without excessive pressure on formwork walls.

Q4: Does slump affect the angle of repose?
A: Yes, higher slump (wetter) concrete will have a lower angle of repose as it flows more easily.

Q5: How accurate is this calculation?
A: This provides a theoretical maximum angle. Actual angles may vary based on concrete composition and environmental factors.
