The document discusses various applications of Roller Compacted Concrete (RCC) dam construction, highlighting the Al Wehdah RCC dam in Jordan/Syria as the 6th fastest constructed RCC dam globally, with a capacity of 75,000 m3 per month. It also mentions the Ralco dam in Chile and several other projects, emphasizing effective construction systems and lower costs associated with RCC. Furthermore, the document provides contact information for Ted Warren, an RCC consultant with extensive international experience.

2. Al Wehdah RCC dam
Jordan/Syria
• Medium paste RCC 60C/60A

3. 103 Al Wehdah RCC dam
nearing completion of RCC
• 6th fastest RCC dam constructed
worldwide when completed

4. Conveyor layout Al Wehdah RCC Dam Jordan/Syria

5. Al Wehdah under construction
2005-2006

6. • Simple installation process
• Less capital costs = Alliance asset and can be sold for
various uses in the mining and quarrying industry

9. RCC delivery system
• 350 m overland conveyor with integrated stepped sectional conveyor
tranfers with swinger discharge conveyor for loading haul trucks on the fill
• Simple system used worldwide successfully for RCC dam construction
• This system was used on 8 of the top 10 fasted constructed RCC dams in
the world (MDA database) with placement rates ranging from 52,000 m3
per month to 125,000 m3 per month
• Al Wehdah Dam was the 6th fastest RCC Dam constructed with an
average monthly rate of 75,000 m3/ month of the 360 RCC dams completed
world wide. (MDA database)
• Access walkways for safety, continuous maintenance ,and inspection
purposes without an interruption to the RCC operation while in production
• Simply mechanical system = Less down time
• Wider conveyor = less speed = less segregation and less maintenance
• Less up front Capital = better value for money

12. All conveyor RCC delivery
system

13. 155 m Ralco Dam Chile
RCC placement 24 hrs
5 th fastest RCC dam constructed
worldwide when completed

14. • I.6 million m3 RCC
• Main conveyor with transfer to feed link conveyor combined
with a tripper conveyor and Crawler Placer system on the fill
• Trucks were loaded on the fill directly from main conveyor
when the complex system used for placement on the dam
was being installed and during down time.
• This system is very effective for large and extremely
complicated RCC dams generally over 1 million m3.
