The Formula Explained
Pressure (P): P = C × R × H
Where C is Concrete Density, R is Pour Rate, and H is the height of concrete.
Glossary of Terms
- Concrete Density: The mass of concrete per unit volume.
- Pour Rate: The speed at which concrete is poured into the formwork.
- Formwork Pressure: The force exerted by the concrete on the formwork.
How It Works: A Step-by-Step Example
Consider a case where concrete density is 2400 kg/m3 and pour rate is 2.5 m/hr. Using the formula P = C × R × H, calculate the pressure exerted for different heights.
Frequently Asked Questions (FAQ)
What is formwork pressure?
Formwork pressure is the pressure exerted by concrete on the formwork while it is being poured.
How do I calculate formwork pressure?
You can use the calculator on this page to determine formwork pressure based on the ACI 347 standards.
Why is accurate calculation of formwork pressure important?
Accurate calculation ensures the safety and stability of the formwork during the concrete pouring process.
Can formwork pressure affect the quality of the final structure?
Yes, incorrect formwork pressure can lead to defects in the concrete, affecting the structural integrity.
What factors influence formwork pressure?
Concrete density, pour rate, and the height of the pour are key factors affecting pressure.
