ตัวกรองผลการค้นหา
Cementitious
แปลว่า(Concrete Engineering) Having cement-like, cementing, or bonding type properties. Material or substance producing bonding properties or cement-like materials.
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.
Maximum Size Aggregate
แปลว่า(Concrete Engineering) Aggregate whose largest particle size is present in sufficient quantity to affect the physical properties of concrete; generally designated by the sieve size on which the maximum amount permitted to be retained is 5 or 10 percent by weight.
Peeling
แปลว่า(Concrete Engineering) A process in which thin flakes of matrix or mortar are broken away from concrete surface; caused by adherence of surface mortar-to forms as forms are removed, or to trowel or float in portland cement plaster.
Dispersing Agent
แปลว่า(Concrete Engineering) An admixture capable of increasing the fluidity of pastes, mortars, or concretes by reduction of interparticle attraction.
Calcine
แปลว่า(Concrete Engineering) To alter composition or physical state by heating to a specific temperature for a specific length of time.
Particle-Size Distribution
แปลว่า(Concrete Engineering) Particle distribution of granular materials among various sizes; for concrete material normally designated as gradation. Usually expressed in terms of cumulative percentages smaller or larger than each of a series of sieve openings or percentages between certain ranges of sieve openings.
Unit Water Content
แปลว่า(Concrete Engineering) The quantity of water per unit volume of freshly mixed concrete, often expressed as gallons or pounds per cubic yard. This is the quantity of water on which the water cement ratio is based, and does not include water absorbed by the aggregate
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.
Sand (ASTM C125)
แปลว่า(Concrete Engineering) That portion of an aggregate passing the No. 4 (4.76 mm) sieve and predominantly retained on the No. 200 (74 micron) sieve.
Portland Blast- slag Cement Furnace (ASTM C 595)
แปลว่า(Concrete Engineering) The product obtained by intimately intergrinding or an intimate and uniform blending a mixture of granulated blast furnace slag and portland-cement clinker
Condensation
แปลว่า(Concrete Engineering) When a moisture laden gas comes in contact with a cooler surface a change of state from gaseous to liquid occurs.
