Wind Farm Concrete
The Concrete Mixing Technology Designed To Build Wind Farms
Roller Compacted Concrete (RCC) is a no-slump concrete compacted by vibratory forces. RCC has demonstrated life spans in Canada of 40+ years and is found worldwide in dams, heavy industry areas (logging, lay down areas, ports, container yards, etc.), airports, roads, and more.
Feedlot Compacted Concrete ™ hard surfacing is a RCC designed for the feedlot industry. Our concrete experts custom design concrete to meet the unique applications of your feedlot using local materials that ensure high quality for your desired lifespan at an economical price.
But there was one surprise…
We did not anticipate when we started this journey the impact this improvement in production efficiency would have on the environmental impact of the wind farm project.
Which could very well be the most important difference in some respects.
Because lets face it… if you’re building a greener energy source, such as a wind farm, you should also make sure the materials used to construct it are Eco-friendly. Don’t you think?
And as you can see in the following comparison chart the differences between technologies environmental impact is staggering: (*the following calculations, despite appearing to be an exaggeration, are actually true calculations based on what CSA recommends)
How is it that drastic? Take a look at the next chart and you should start to see how the numbers are so drastically different because of the efficiency differences between the 3 technologies. Fact is, Omni-Mixing Technology is the only type of technology currently capable of providing fresh concrete on-site uninterrupted for a project of this size with only 2 mixers.
The following chart compares these same three technologies from a production standpoint for wind farm construction projects:
Now what about quality? (which should never be compromised, but especially on a mass pour)
With respect to CSA A23.1 / 14, the performance criteria for any project will be:
The project specifications for plastic concrete including: slump, air content, consistency, w / cm ratio, age of concrete, temperature, workability, place-ability, and finish-ability.
1. The project specifications for hardened concrete include: compression strength / flexural strength as requested, permeability, durability (freeze-thaw, chemical attack, wear resistance) and longevity.
2. Concrete Genius, using Omni-Mixing Technology, boasts an unmatched performance of 100% for 8 consecutive years success rate on all of these CSA performance tests (including air content, slump, and strength).
– Public schools
– Airport Runways and Deicing Pads
– Structural and flat work for Oil Sands facilities
– Many Department of Transportation projects
– and many medium and large sized commercial and industrial facilities in Alberta, BC, and Alaska
…All with 100% performance
CSA defines a mass pour anything over 1m thick. A windmill project would be defined as a mass pour, meaning temperature is extremely important and concrete must be delivered below 20 degrees Celsius according to CSA.
At an ambient temperature of 25 degrees C, 20 degree C aggregates, 8 degree C water with a 20 minute distance from site concrete in a drum would be at 31 degrees C when it is being poured. Therefore, risk of detrimental concrete temperatures is a high risk. In those same conditions Omni-Mixing Technology would be below 20 degrees C, meeting CSA requirements.
Potential concrete problems due to high concrete temperatures include:
– Increased water demand
– Increased rate of slump loss
– Increased rate of setting
– Increased tendency for plastic-shrinkage cracking
– Increased difficulty in controlling entrained air content
– Decreased 28-day and later strengths
– Increased tendency for differential thermal cracking
– Greater variability in surface appearance
– Increased permeability
If you can immediately remove these threats by providing fresh concrete that is accurately measured and controlled why wouldn’t you?
Omni-Mixing Technology is the first platform to positively ensure W/CM ratios are in speculation. Taking thousands of precise measurement samples per cubic meter of concrete. Meaning no surprises.
And if you can use only 0.2% of the water, 2.5% of the diesel fuel, and create only 0.6% of the CO2 compared to a batch plant on a project that’s main purpose is to decrease emissions and provide a greener energy source… why wouldn’t you?
