The ratio of non-absorbable dye (Evans blue) and glucose was used to follow the glucose absorption in the anterior region of the midgut (Bifano et al., 2010). The effect of ions in sugar absorption was tested by the addition of 50 mM K 2 SO 4, or 50 mM Na 2 SO 4 to the feeding medium described above and repeating the same procedure.
Water absorption in shearing can be classified into three types, including partial water absorption, complete water absorption, and compulsory water absorption. Under the influence of water absorption in shearing, even a strongly dilative sand under naturally drained conditions could experience instability and large shear deformation.

Fractal dimensions can be used to assess damage degree and CWA levels in ASC. ASC-100 exhibits better frost resistance and lower levels of capillary absorption. Pore sizes below 50 nm are more favourable for frost durability of ASC.
Silica sand is the main raw material for glass, ceramics, refractory materials, etc. However, due to the strict requirements of glass raw materials for ultrafine powders, most of the silica sand fine powders less than 0.125 mm are not recycled, which leads about 10 million tons of silica sand tailings discharge in China each year [12] Such a large amount of silica sand …

This means the different aggregates have varying absorption rates as water begins to fill the permeable pore voids. The absorption rate of fine aggregates can be foun. d by taking the mass of saturated surface dry (SSD) sand [S] minus the mass of oven dry sand [A], all over the mass of oven dry sand, and multiplying by 100 to get a percentage.

Unwashed sand has a higher water absorption range of 2.5–3%, whereas washed sand has a slightly lower water absorption range of 2–2.5%. These differences suggest that washing the sand helps reduce its water absorption capacity, potentially making it a more suitable choice for certain applications where lower water retention is desired.

M Sand and quarry dust have more angularity, rougher surface, higher total specific surface, and lower presence of deleterious substances than river sand, offshore sand, and sea sand.
Fine aggregate, also known as sand, plays a crucial role in the manufacturing of concrete and mortar. One of the key properties of fine aggregate that affects its suitability for construction use is its specific gravity and water absorption.
For recycled concrete sands, similarly to the case of crushed sand, drying rate is constant until a water content of 9%, which corresponds to the water absorption of the particles (Cf. Table 1). For crushed and recycled sands, water absorption seems therefore to be a key feature of the change in drying kinetics.
Saturated water absorption rate tests are used to reveal the extent of continuous pores in a concrete specimen. The fact that compacted specimens have a lower saturated water absorption rate is an indication that they have fewer continuous pores. Changes in the saturated water absorption rate over time also indicate the growth of hydration ...

The level of sound absorption could be characterized by the absorption coefficient (α) which corresponds to the amount of striking energy absorbed on the material surface. Values α strongly vary with frequency ranging from 0 to 1, where zero signs that material has no absorption and α = 1 means full sound absorption.
