Center of Gravity (CG):
แปลว่า(english) The location of the resultant of gravity forces on an object or objects: sometimes called center of mass.
Effluent based standards
แปลว่า(Environmental Engineering) Standards which set concentration or mass per time limits on the effluent being discharged to a receiving water.
ASR - Alkali-Silica Reactivity
แปลว่า(Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete.
Plastic
แปลว่า(Concrete Engineering) A condition of freshly mixed concrete. mortar or cement -paste indicating that it is workable and readily re-moldable, is cohesive, and has an ample content of fines and cement but is not over wet.
Cementitious

Rock Pocket
แปลว่า(Concrete Engineering) Area or portion of hardened concrete which is deficient in mortar and consisting primarily of coarse aggregate and open voids; caused by insufficient consolidation or separation during placement, or both; by leakage from form.
Impermeable
แปลว่า(Concrete Engineering) The ability of a material or product to reduce or eliminate gaseous transmissions through it's mass; measured as the rate of Water Vapor Transmission (WVT). Note: Not all materials that are waterproof are vaporproof; all materials that are vaporproof are inherently waterproof.
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.
Peeling
แปลว่า(Concrete Engineering) A process in which thin flakes of matrix or mortar are broken away from concrete surface; caused by adherence of surface mortar-to forms as forms are removed, or to trowel or float in portland cement plaster.
Dispersing Agent
แปลว่า(Concrete Engineering) An admixture capable of increasing the fluidity of pastes, mortars, or concretes by reduction of interparticle attraction.
Body force:
แปลว่า(english) An external force acting throughout the mass of a body. Gravity is a body force. An inertial force is a body force.
