Do you perhaps have a backfilling project? What do you usually use to accomplish it? While we have a number of choices, Flowable Fill has quickly emerged as a great innovation and a popular alternative for backfilling.
According to U.S. Department of Transportation Federal Highway Administration, Flowable Fill refers to a cementitious slurry consisting of a mixture of fine aggregate or filler, water, and cementitious material(s), which is used primarily as a backfill in lieu of compacted earth. This mixture is capable of filling all voids in irregular excavations and hard to reach places (such as under and around pipes), is self-leveling, and hardens in a matter of a few hours without the need for compaction in layers. Flowable Fill is sometimes referred to as controlled density fill (CDF), controlled low strength material (CLSM), lean concrete slurry, and unshrinkable Fill.
Flowable Fill is popular for no reason! Since it's a chemical admixture made from a combination of different materials, the percentages of these materials can be adjusted for varying results. Therefore, the design flexibility of flowable fill concrete gives several benefits to the engineer. So, what are the advantages of using Flowable Fill for your NEXT project?
SUPER-QUICK SETTING Flowable fill is a definite time-saver, but the results are even better when it's the fast-setting variant. As its name suggests, it takes far less time to set - only around 20 minutes - after which you can cover it with asphalt and concrete. All of this gets completed in little more than an hour - a fraction of the time it takes with typical flowable fill concrete.
SUITABLE FOR APPLICATION IN ANY WEATHER This solution can dispel water from trenches or similar places, eliminating the need for water pumps. In cold weather, you can use flowable fill after heating it, similar to ready-mixed concrete.
STRONG, RESILIENT, MULTIPURPOSE Flowable fill boasts a greater load-carrying capacity in comparison with granular fill or compacted soil. This is due to decreased permeability, which allows it to gain compressive strengths over a thousand psi. Flowable fill mixtures can also be modified to fulfil various needs. For example, adding fly ash increases strength, whereas water boosts viability. Changing the quantities of admixtures in turn changes setting times.
EASY AVAILABILITY OF INGREDIENTS You can easily mix up some flowable fill using readily available materials like cement, water, sand, and fly ash. Fly ash is a byproduct of coal burned by power plants. Considered a waste product, it proves useful for this purpose as it boosts the strength of concrete - in a cost-efficient manner.
INEXPENSIVE This self-levelling product basically does most of the work on its own, since it settles as soon as it's poured. Therefore, all it needs is one person for placement, unlike conventional granular fill that requires at least two labourers to fulfil the duties of placement and compaction. This helps you save the time and cost of hiring backhoes and compactors.
CONVENIENT TO DELIVER AND APPLY Thanks to Gunner-Concrete mobile mixers, you can have flowable fill delivered to any jobsite you desire, regardless of how remote or densely populated the area is. Moreover, we can pour it through various means like conveyors, pumps, chutes, or buckets. And since it's self-levelling - it requires no compacting or spreading, nor do you have to demolish existing concrete. Simply add it to any cracks and crevices and save the land from settlement by providing stability to the soil below. Reap the amazing benefits of Flowable Fill with Gunner-Concrete Volumetric Mixers! We have the best equipment for making flowable fill concrete capable of achieving the perfect mixtures while producing the required amount. What's even better is that you only pay for what you use!
