What are some recipes for making a do-it-yourself version of flowable fill? ( as defined by https://www.nrmca.org/aboutconcrete/cips/17p.pdf )
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.
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.
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.
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.
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.
