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.

Bench Rammer

แปลว่า(english) A short rammer used by bench molders.

Bench Lathe

แปลว่า(english) A small lathe mounted on a bench or table.

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.

adjustable resistance

แปลว่า(ไฟฟ้า) บางทีก็เรียก variable resistance ความฝืดของวัตถุของกระแสไฟฟ้าที่ปรับให้เพิ่มขึ้นหรือลดลงได้

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.

regular maintenance

แปลว่าการบำรุงรักษาปกติ : ดู maintenance, regular

Preplaced Concrete

แปลว่า(Concrete Engineering) Concrete manufactured by placing clean, graded coarse aggregate in a form and later injecting a portland cement-sand grout under pressure, to fill the voids.
