unavoidable
แปลว่าหลีกเลี่ยงไม่ได้
Rock Pocket
แปลว่า(Concrete Engineering) Area or portion of hardened concrete which is deficient in mortar and consisting primarily of coarse aggregate and open voids; caused by insufficient consolidation or separation during placement, or both; by leakage from form.
void (1)
แปลว่าช่องว่างที่อยู่ภายในเนื้อของดิน หิน หรือคอนกรีต
Avoidance of Interference
แปลว่าการหลีกเลี่ยงการรบกวน
ovoid
แปลว่ารุปทรงอย่างรูปไข่ แต่ปลายข้างหนึ่งเรียงและแหลมกว่า
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.
void ratio
แปลว่าอัตราส่วนโพรง
water void
แปลว่าโพรงน้ำ
Avoidable Accident
แปลว่าอุบัติเหตุที่สามารถหลีกเลี่ยงได้
Cellular Concrete
แปลว่า(Concrete Engineering) A lightweight product consisting of portland cement, cement-pozzolan, cement sand, lime-pozzolan, or lime-sand pastes, or pastes containing blends of these ingredients and having a homogenous void or cell structure, attained with gas forming chemicals or foaming agents. For cellular concretes, containing binder ingredients other than or in addition to portland cement, autoclave curing is usually employed.
air void
แปลว่าโพรงอากาศ
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.
