Sand porosity

Webb9.8: Soil Permeability. Soil permeability is the quality of a soil enabling it to transmit air or water through the soil pores. Texture, structure, cracking, and the amount of organic matter influence the permeability. The permeability of the least permeable horizon should be estimated because this becomes the most limiting horizon for water ... Webb7 feb. 2024 · The cause of this extra porosity is the lack of fine aggregate (sand) and the uniform-sized coarse aggregate in the design of the mix. This, in turn, affects the Workability of the fresh concrete due to the presence of old mortar pores, which absorb a high amount of water during mixing.
