Retardation
แปลว่า(Concrete Engineering) Delaying the hardening or strength gain of fresh concrete, mortar or grout.
Cement Gel
แปลว่า(Concrete Engineering) The colloidal gel (glue like) material that makes up the major portion of the porous mass of which hydrated cement paste is composed.
Aluminous Cement
แปลว่า(Concrete Engineering) A hydraulic cement in which the principal constituents are calcium aluminates, instead of calcium silicates which comprise the major ingredients of portland cement. (See calcium aluminate cement)
Screen (or Sieve)
แปลว่า(Concrete Engineering) A metallic sheet or plate, woven wire cloth, or similar device, with regularly spaced openings of uniform size, mounted in a suitable frame or holder for use in separating material according to size.
Rebound
แปลว่า(Concrete Engineering) Wet shotcrete or sand and cement which bounces away from a surface again at which pneumatically applied mortar is being projected.
prestressed concrete slab
แปลว่าแผ่นปูพื้นถนน หรือทางเดินคอนกรีตอัดแรง
Pumping (of Pavements)
แปลว่า(Concrete Engineering) The ejection of a mixture of water and solid materials such as clay or silt along cracks, transverse or longitudinal joints, and along pavement edges caused by downward slab movement due to the passage of heavy loads, machinery or equipment over the pavement after free water has accumulated in or on the subbase, subgrade or basecourse.
Temperature Rise
แปลว่า(Concrete Engineering) The increase of concrete temperature caused by heat of hydration and heat from other sources.
Adsorption Water
แปลว่า(Concrete Engineering) Water held on surfaces in a material by either physical and/or chemical forces.
Plane of Weakness
แปลว่า(Concrete Engineering) The plane along which a structure under stress will tend to fracture; may exist because of the nature of the structure and its loading, by accident, or by design.
AAC - Autoclaved Aerated Concrete
แปลว่า(Concrete Engineering) Exceptionally lightweight precast concrete with high thermal qualities and fire resistence. Suitable for cutting with ordinary hand tools. Mix design is composed of portland cement, sand or siliceous material, lime, gypsum, finely powdered aluminum, and water. Initial mix is a combination of portland cement, sand, lime and gypsum to produce a slurry. Finely powdered aluminum mixed into a paste is added prior to placement into large, rail-like forms. The finely powdered aluminum reacts with the alkaline components of the cement and lime to produce hydrogen gas, which increases the volume approximately five times producing a uniformly, dispersed cellular structure. Units are cut to required shape. Units are placed in an autoclave, an enclosed pressurized chamber, and steam cured at 3500 F. Approximately 80% of the ultimate volume consists of air voids.
