Particle-Size Distribution

แปลว่า(Concrete Engineering) Particle distribution of granular materials among various sizes; for concrete material normally designated as gradation. Usually expressed in terms of cumulative percentages smaller or larger than each of a series of sieve openings or percentages between certain ranges of sieve openings.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Fluidization

แปลว่า(Environmental Engineering) The suspension of particles by sufficient upward velocity of the fluid. During fluidization the gravity force is overcome by a combination of buoyancy and fluid friction.

Dispersing Agent

แปลว่า(Concrete Engineering) An admixture capable of increasing the fluidity of pastes, mortars, or concretes by reduction of interparticle attraction.

Discrete settling

แปลว่า(Environmental Engineering) Settling in which individual particles settle independently, neither agglomerating or interfering with the settling of the other particles present. This occurs in waters with a low concentration of particles.

BETA RATIO (#)

แปลว่า(english) The amount, expressed as a ratio, of particles in a fluid stream upstream of a filter, after the fluid posses through a filter, divided by the amount of particles downstream, for a particular size particle.

Maximum Size Aggregate

แปลว่า(Concrete Engineering) Aggregate whose largest particle size is present in sufficient quantity to affect the physical properties of concrete; generally designated by the sieve size on which the maximum amount permitted to be retained is 5 or 10 percent by weight.
