What is ACI 347?
ACI 347-04 A section on contract documents explains the kind and amount of specification guidance the engineer/architect should provide for the contractor. The remainder of the report advises the formwork engineer/ contractor on the best ways to meet the specification requirements safely and economically.
Who has the responsibility for concrete formwork design the contractor or the architect engineer?
Responsibility for the design of the formwork rests with the contractor or the formwork engineer hired by the contractor to design and be responsible for the formwork. 2.1.
What is air entrained portland cement concrete quite weak in?
Wall thickness, tie load capacity, break back, and tie extension. What is Air-entrained Portland cement Concrete quite weak in? A. Tension.
Do you need both an architect and structural engineer?
If you have onboarded a structural engineer already before hiring an architect, then you may not need an architect. Structural engineers basically check the adequacy of a design based on code and safety, so hiring an architect will not change the design much once an engineer has provided one.
What is concrete tolerance?
Definition: the permitted deviation from a specified dimension, location, or quantity.- ACI Concrete Terminology. Tolerances are a means to establish permissible variation in dimension and location, giving both the designer and the contractor limits within which the work is to be performed.
Why is air entrainment used in PCC?
Forming Air in Concrete The shearing action of mixer blades continuously breaks up the air into a fine system of bubbles. Air-entrain- ing admixtures stabilize these air bubbles.
How is form work calculated?
For simple square and rectangular forms, simply multiply length x width to know how much formwork you need. For a circular base, multiply the square of the radius by pi (πr²).
What are requirements of Form work?
Requirements of good Formwork Entire formwork should be rigidly constructed and propped, so that there should be no deformation in the shape and retain its original shape. Deflection and shrinkage should be minimum. The joins should be tight enough to minimize the leakage of cement grout.
What are the basic requirements of formwork?
Requirements Of A Good Formwork:
- It should be adequately strong to withstand an extensive variety of dead and live loads.
- It should be inflexibly built and efficiently propped and supported to hold its shape without undue deflection.
- The joints in the formwork should be tight enough to prevent leakage of cement grout.
