1. Hurdles - Production

2. Quality
How do you control the quality of a mix that may have recycled concrete, rubber, plastic, etc.

3. Quality
How do you control the quality of materials that come directly from nature; bamboo etc.

4. Form Work (Water-tight Forms?)

5. Curing/Heat
We may need heating or ultra violet light chambers instead of curing chambers

6. Safety More heat may be required Hazardous chemicals may be required

7. Joints

8. Training
We may be working with materials and equipment that we have never worked with before.

9. Hurdles - Engineering

10. Overzealous Materials Sales People
A Study of Fiber Reinforced Concrete Pipe

11. Lack of Methods to Validate New Materials
C13.03 – Determining the Effects of Biogenic Sulfuric Acid on Concrete Pipe and Structures
Since 2003?
To develop methods of testing, specifications, definitions, practices and guidelines relating to concrete pipe, manholes and components, in which the concrete is modified by additives and compounds, to determine the effectiveness of the modified concrete to resist sulfuric acid.

12. Developing the Appropriate Standards

Developing the Appropriate Standards

13. Where the Comments Come From
13 Negatives on initial SFRCP Ballot
4 from Competitive Pipe Materials
2 From Alternative Reinforcing Suppliers
2 from Gasket Suppliers
2 from Consultants
1 from DOT
2 from Concrete Pipe Producers

14. Competition 4 Negatives on last SFRCP Ballot Competitive Pipe Material
Retired Concrete Pipe Individual
Alternative Reinforcing Supplier
*Our competitors own concrete pipe plants

15. Developing Standards for New Products
Steel Fiber Reinforced Concrete Pipe
“This standard needs to provide standard wall thicknesses.”
“Current reinforced concrete pipe specifications require a minimum concrete cover over the reinforcing steel…”
“The use of 4000 psi concrete is not acceptable for this product.”

16. Developing Standards for New Products
Steel Fiber Reinforced Concrete Pipe
“What is collapse?”
“Also, who assumes the failure of a steel fiber reinforced concrete culvert?”
