Jacking Force

แปลว่า(Concrete Engineering) The temporary force exerted by the jacking device which introduces tension into the tendons. Jacking Stress In prestress concrete, the maximum stress occurring in a tendon during stressing.

Flexural Strength

แปลว่า(Concrete Engineering) A property of a solid that indicates its ability to withstand bending.

Vicat Apparatus

แปลว่า(Concrete Engineering) A penetration device used to determine the setting characteristics of hydraulic cements.

Bleeding, Bleed Water

แปลว่า(Concrete Engineering) A form of segregation in which some of the water in a mix tends to rise to the surface of freshly placed concrete. Known also as water gain.

Sacking

แปลว่า(Concrete Engineering) Removing or alleviating defects on a concrete surface by applying a mixture of sand and cement to the moistened surface and rubbing with a coarse material such as burlap.

Sulfate Resistance

แปลว่า(Concrete Engineering) Ability of cement paste, aggregate, or mixtures thereof to withstand sulfate attack.

Tilt-up

แปลว่า(Concrete Engineering) A method of concrete construction such as where members are cast horizontally near their eventual position, usually on a recently placed slab, and then tilted into place after removal of forms.

Slip Form

แปลว่า(Concrete Engineering) A form which is raised or pulled as concrete is placed; may move vertically to form wails, stacks, bins or silos, usually of uniform cross section from bottom to top; or a generally horizontal direction to lay concrete evenly for highways, on slopes and inverts of canals, tunnels, and siphons.

Adsorption Water

แปลว่า(Concrete Engineering) Water held on surfaces in a material by either physical and/or chemical forces.

Neat Cement-Paste

แปลว่า(Concrete Engineering) A mixture of water and hydraulic cement, both before and after setting and hardening.

Magnetite

แปลว่า(Concrete Engineering) An aggregate used in heavy weight concrete, consisting primarily of ferrous metaferrite (Fe304). A black magnetic iron ore with a specific gravity of approximately 5.2 and a Mohs hardness of about 6.

Consolidation

แปลว่า(Concrete Engineering) Compaction usually accomplished by vibration of newly placed concrete to minimum practical volume, to mold it within form shapes and around embedded parts and reinforcement, and to eliminate voids other than entrained air.
