In summary, DIY flowable fill can be made using a combination of cement, water, and fine aggregate such as sand. The ratio of each ingredient can be adjusted to achieve the desired consistency and strength. Various additives can also be used to improve the flowability and stability of the mixture. It is important to carefully follow a recipe and mix the ingredients thoroughly before using the DIY flowable fill for construction or other projects.

That's an interesting term that I never heard of before.
Have you checked the references cited on that page you linked?

There's https://www.flowablefill.org/downloads/CLSMSpecifications1.pdf , but it's hardly a DIY guide.

In this document here there are some recipes. My humble opinion is that this material is ~ the marketing manifestation of the will to sell the worst possible concrete (preferably with as much air instead of concrete as possible) you are able to mix up.
But maybe you would get more useful responses if you ask for a solution of a well described problem instead of a recipe from the cookbook

1. What is flowable fill and why is it used?
Flowable fill is a self-leveling, cementitious material that is used as a substitute for compacted backfill in construction projects. It is commonly used to fill voids, trenches, and other spaces where traditional backfill materials may be difficult or time-consuming to place. Flowable fill is also used to improve the stability and load-bearing capacity of the surrounding soil.
2. What are the main ingredients in a DIY flowable fill recipe?
The main ingredients in a DIY flowable fill recipe typically include cement, fine aggregate (such as sand or fly ash), water, and sometimes additives such as plasticizers or accelerators. The specific proportions of these ingredients may vary depending on the desired strength and flow characteristics of the flowable fill.
3. How do I mix and place DIY flowable fill?
To mix DIY flowable fill, first combine the dry ingredients (cement and fine aggregate) in a large container. Gradually add water and mix until the desired consistency is achieved. The mixture should be fluid enough to flow easily, but not so watery that it loses strength. Once mixed, the flowable fill can be placed using a pump or by pouring it into the desired location.
4. How long does it take for DIY flowable fill to set?
The setting time of flowable fill can vary depending on the specific recipe and environmental conditions. In general, it can take anywhere from a few hours to a full day for the flowable fill to set and reach its maximum strength. It is important to follow the recommended curing time before placing any additional loads on the flowable fill.
5. Can DIY flowable fill be used in all types of construction projects?
While flowable fill is a versatile material, it may not be suitable for all types of construction projects. It is typically used in non-structural applications, such as filling voids or stabilizing soil. It is important to consult with a professional engineer to determine if flowable fill is the appropriate material for your specific project.
