Cement, Portland (ASTM C150) (Concrete Engineering)

แปลว่าA powdery substance made by burning, at a high temperature, a mixture of clay and limestone producing lumps called “clinkers” which are ground into a fine powder consisting of hydraulic calcium silicates. For non-portland cements, see aluminous cement.

Construction Joint

แปลว่า(Concrete Engineering) The contact between the placed concrete and concrete surfaces, against or upon which concrete is to be placed and to which new concrete is to adhere, that has become so rigid that the new concrete cannot be incorporated integrally by vibration with that previously placed. Unformed construction joints are horizontally placed or nearly so.

Cure

แปลว่า(Concrete Engineering) Method of maintaining sufficient internal humidity and proper temperature for freshly placed concrete to assure proper hydration of the cement, and proper hardening of the concrete.

Air Entraining Agent

แปลว่า(Concrete Engineering) An addition for hydraulic cement, or an admixture for concrete or mortar which entrains air in the form of minute bubbles in the concrete or mortar during mixing.

Non-agitating Unit

แปลว่า(Concrete Engineering) A truck-mounted unit for transporting ready-mixed concrete short distances, not equipped to provide agitation (slow mixing) during delivery.

Pining

แปลว่า(Concrete Engineering) Development of relatively small cavities in a concrete surface, due to phenomena such as cavitation or corrosion.

Plastic Consistency

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

Elastic Shortening

แปลว่า(Concrete Engineering) The shortening of a member in pre-stressed concrete which occurs on the application of forces induced by prestressing.

Air Content

แปลว่า(Concrete Engineering) The amount of entrained or entrapped air in concrete or mortar, exclusive of pore space in aggregate particles, usually expressed as a percentage of total volume of concrete or mortar.

Plasticity

แปลว่า(Concrete Engineering) Property of freshly mixed concrete, cement paste or mortar which determines its ease of molding or resistance to deformation.

Bush-hammer

แปลว่า(Concrete Engineering) A tool having a serrated face, as rows of pyramidal points, used to develop an architectural finish for concrete surfaces.

Precast

แปลว่า(Concrete Engineering) A concrete unit, structure or member that is cast and cured in an area other than its final position or place.
