หรือคุณกำลังค้นหา Air Content, Gillmore Needle, Water-Cement Ratio, Beryllium Copper, Acid
Acid
แปลว่า(english) 1) A solution or liquid with a pH less than 7, 2) term applied to slags, refractors, and minerals containing a high percentage of silica.
Beryllium Copper
แปลว่า(english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc.
Air Content
แปลว่า(Concrete Engineering) The amount of entrained or entrapped air in concrete or mortar, exclusive of pore space in aggregate particles, usually expressed as a percentage of total volume of concrete or mortar.
percentage of reinforcement
แปลว่าจำนวนร้อยละของเหล็กเสริม
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.
Gillmore Needle
แปลว่า(Concrete Engineering) A device used in determining time of setting of hydraulic cement, described in ASTM 0 266. Gradation The sizing of granular materials; for concrete materials, usually expressed in terms of cumulative percentages larger or smaller than each of a series of sieve openings or the percentages between certain ranges of sieve openings.
Release of Retained Percentage Bond
แปลว่าหนังสือค้ำประกันที่ผู้รับเหมาให้กับเจ้าของโครงการเพื่อใช้แทนเงินประกันผลงาน ในกรณีผู้รับเหมาประสงค์ขอเบิกเงินดังกล่าวก่อนครบอายุการรับประกันผลงาน
Water-Cement Ratio
แปลว่า(Concrete Engineering) The ratio of the amount of water, exclusive of that absorbed by the aggregates, to the amount of cement in a concrete mix. Typically expressed as percentage of water, by weight in pounds, to the total weight of portland cement, fly ash, and any other cementitious material, per cubic yard, exclusive of any aggregates.
