Retardation

แปลว่า(Concrete Engineering) Delaying the hardening or strength gain of fresh concrete, mortar or grout.

Pretensioning

แปลว่า(Concrete Engineering) A method of prestressing reinforced concrete in which the steel is stressed before the concrete has hardened and restrained from gaining its unstressed position by bond to the concrete.

GFRC - Glass Fiber Reinforced Concrete

แปลว่า(Concrete Engineering) Concrete panels, usually architectural designs, reinforced with a high zirconia (16% minimum), alkali-resistant glass fiber. Optimum glass fiber content of 5% by weight. Lower fiber content results in lower early ultimate strengths, higher fiber content can produce composite compaction and consolidation difficulties.

Consistency

แปลว่า(Concrete Engineering) The degree of plasticity of fresh concrete or mortar The normal measure of consistency is slump for concrete and flow for mortar.

Mass Curing

แปลว่า(Concrete Engineering) Adiabatic curing, using sealed containers.

Non-evaporable Water

แปลว่า(Concrete Engineering) The water in concrete which is irremovable by oven drying; chemically combined during cement hydration.

Alkali-Aggregate Reaction

แปลว่า(Concrete Engineering) Older terminology for Alkali-Silica Reactivity (ASR).

Temperature Rise

แปลว่า(Concrete Engineering) The increase of concrete temperature caused by heat of hydration and heat from other sources.

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.

double T. prestressed concrete floor slab

แปลว่าแผ่นซีเมนต์คอนกรีตอัดแรง มีขารูปตัว ทีคู่ สำหรับปูพื้น

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.
