Engineering Applications
More InfoThe physical properties of Reclime also make it excellent for use as an engineering aggregate. Reclime has been used in:
- Ready-mix concrete
- Structural fill
- Buffering of acid mine drainage.
- Fine-Grained Material
- Composed primarily of fine sand, silt, and clay size particles.
- Non-plastic
- Classified as ML or sandy silt
- Exceeds the minimum standards for agricultural lime established by the Lime Law of numerous states.
- Compaction
- Maximum dry density of Reclime of about 116 pounds per cubic foot (pcf) at an optimum moisture content of about 16.7%
- Wet density at 95% of maximum dry density at optimum moisture content of about 128 pcf
- Easy to place and compact due to its particle size and because it is a non-cohesive material
- Will not produce "clods" like clay does during grading activities.
- Permeability
- Low to very low permeability
- Coefficient of permeability when compacted to a density approaching its maximum dry
- Shear Strength
- High shear strength at 90% of Standard Proctor maximum dry density.
- Can be placed at slopes as steep as 2:1 (horizontal:vertical)
- Can support moderately to highly loaded foundations
- Cement and Flowable Fill
- Cementitious properties result from high calcium content
- Studies have shown that Reclime will develop alone, or when mixed with other materials
- Road Base Stabilization
- Can be used instead of calcium chloride to stabilize or reclaim soft road bases
- Expansion Characteristics
- Reclime is not expansive
- Tests mixing Reclime with slag showed that the mixture had a 0% expansion
