HRM High Reactivity Metakaolin

แปลว่า(Concrete Engineering) Refined form of an ASTM C618, Class N (natural) pozzolan. A high performance, mineral admixture, similar in performance to silica fume, additionally comparable in cost. Pure white powdered in form will, not effect the natural color or darken concrete as silica fume does. Suitable for high-performance color matching in architectural concrete. Dosage at 5% to 10%, of cement by weight. No bleed water, better finishability, more creamy, cleanup is easier with slightly higher 28 day strengths and 25% - 35% less plasticizer is required than silica fume.

Stiffness:

แปลว่า(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.

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.

Elastic:

แปลว่า(english) A material or structure is said to behave elastically if it returns to its original geometry upon unloading.

Pin support:

แปลว่า(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.

Milestones

แปลว่า(Software Engineering) a point in time that is used to indicate progress during a project

Nitrification

แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.

Adiabatic Curing

แปลว่า(Concrete Engineering) The maintenance of ambient conditions during the setting and hardening of concrete so that heat is neither lost nor gained from the surroundings of the concrete.

Change of State

แปลว่า(Concrete Engineering) The process whereby liquid is heated to the point of evaporation changing the liquid into a gas the condensation of a gas on a cooler surface returning it from gaseous to liquid form.

Acute Angle

แปลว่า(english) An angle that is less than 90 degrees.

By Coil

แปลว่า(english) Selling term which refers to product sold in the form of a coil vs. cut plate. "Bi Coil" is also used in production to refer to coils vs. cut plate

AIR BLEEDER AUTOMATIC

แปลว่า(english) A valve that is fit into a hydraulic pipeline to facilitate automatic release of air trapped in the pipeline. See also AIR BLEEDER, MANUAL.
