The plugging of a pore throat by polymer composite gel microspheres mainly relies on the expansion of particles following water absorption
. When a certain number of particles accumulate in the throat, a plug can be generated for profile control.
Water penetration into concrete mainly depends on the force of capillary absorption and hydrostatic pressure, whereas the water-saturated state is difficult to reach except for the concrete exposed to the condition of high hydrostatic pressure, such as the deep sea environment; consequently, almost all of the water penetration into concrete is mainly by the force of capillary absorption, and the test of capillary water absorption
is developed to evaluate the permeability of concrete [13, 14].
ABSTRACT: The effect of variation on water plaster ratio for two unknown Gypsum plaster were determined and been compared with common Gypsum plaster in terms of its absorptive properties (porosity and water absorption
) and flexural strength.
The seed water absorption
presented "S"-shaped curve with seed soaking time, including sharp, stable and saturated water absorption
 synthesized the starch graft superabsorbent polymer with larger water absorption
capacity through radical polymerization in aqueous solution.
The water absorption
was determined from the difference between dry mass and surface dry mass after immersion in water at a temperature of 20[degrees]C for 8 h.
was tested according to BS 1881:122.
Thickness Swelling (TS) and water absorption
(WA)) of particle board have been investigated and the results have been compared with conventional wooden particleboard .
ABSTRACT: In this research, effect of Styrene-Butadiene Rubber (SBR) latex on water absorption
and compressive strength of concrete has been studied.
The effects of formation conditions and rice straw powder content on the mechanical properties, water absorption
, and moisture absorption performance of the composites were studied.
Following a detailed petrographic examination, physico-mechanical properties including unconfined compressive strength, unconfined tensile strength, water absorption
, specific gravity and porosity of the collected samples were determined.
Tests for workability, bleeding, density, strength, water absorption
, sorption, and ultrasonic pulse velocity (UPV) were conducted .
