Flocculant settling

(Environmental Engineering) Settling in which particle concentrations are sufficiently high that particle agglomeration occurs. This results in a reduction in the number of particles and an increase in average particle mass. As agglomeration occurs higher settling velocities result.

Boron (chemical symbol B)

(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.

Sulfate Attack

(Concrete Engineering) Deleterious chemical and/or physical re-action between sulfates in ground water or soil and certain constituents in cement, which result in expansion and disruption of the concrete.

Plastic Consistency

(Concrete Engineering) Condition in which concrete, mortar, or cement paste will sustain deformation continuously in any direction without rupture.

Trace contaminants

(Environmental Engineering) Contamination found in trace (very low) levels.

Cybernetic

(Environmental Engineering) Systems which change in response to feedback.

Base Metal Contamination

(english) Dirt or other impurities in the steel strip.

Burnthrough

(english) In shell molding, resin burned out too soon.
