(Concrete Engineering) The shortening of a member in pre-stressed concrete which occurs on the application of forces induced by prestressing.
(english) Ingot mold, with the top constricted; used in the manufacture of capped steel, the metal in the constriction being covered with a cap fitting into the bottle-neck, which stops rimming action by trapping escaping gases.
(Environmental Engineering) The conversion of atmospheric (or dissolved) nitrogen gas into nitrate by microorganisms.
(english) A property of an object measured by the degree that it resists acceleration.
(Concrete Engineering) The product obtained by pulverizing clinker consisting essentially of hydraulic calcium silicates.

(english) Irregular-shaped surface cavities in a casting containing carbonaceous matter. Caused by spilling off of the blacking from the mold surface.
(english) The roll above the bridle rolls used to thread the strip. Also is used to steer the strip through the bridle.
(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.
(Environmental Engineering) The dissolving of molecular oxygen from the atmosphere into the water.
(english) Joining two edges or ends by placing one against the other and welding them.
(Concrete Engineering) The volume of an ingredient in its solid state, without voids between individual pieces or particles, in the case of fluids, the cubic content occupied. In concrete, the actual volume occupied by the different ingredients determined by dividing the weight of each ingredient pounds, by ifs specific gravity, times the weight of one cubic foot of water in pounds. Example: Absolute Volume of one sack of cement equals: 94 ๗ (3.15X62.4) = 0.478 cubic feet
