|
| The failure of both parties to a contract to abide by its terms.
|
| A slaughterhouse; a place where animals are butchered for food.
|
| A distortion of an image produced by a faulty lens or mirror.
|
| A large above ground vessel used for the storage of liquids.
|
| Scrape or wear away by friction.
|
| A rule stating that with given concrete materials and conditions of test, the ratio of the amount of water to the amount of the cement in the mixture determines the strength of the concrete, provided the mixture is of a workable consistency.
|
| Ability of a surface to resist being worn away by rubbing and friction.
|
| Wearing away by friction.
|
| In closed coating of paper no adhesive is exposed, as surface of paper is completely covered with abrasive; in open coating, surface of backing paper is covered with regulated amount of abrasive, exposing the adhesive; space between the abrasive grains rces loading and filling when sanding gummy or soft materials.
|
| Paper with an abrasive surface; sandpaper, emery paper; garnet paper.
|
| Floor tile that has been roughened to be slip-resistant.
|
| A surface that has been roughened for safety or for warning.
|
| A substance used for wearing, grinding, cleaning, or polishing by rubbing or grinding.
|
| A plastic pipe sold in 10 and 20 foot lengths in various diameters for plumbing stacks and drains; used primarily for drain lines.
|
| Acrylonitrile Butadiene Styrene; a plastic used for piping; has high resistance to impact, heat, and chemicals.
|
| The density of water vapor per unit volume of air.
|
| The pressure measured by a gauge plus a correction for the effect of air pressure on the gauge (l4.7 psi at sea level).
|
| Temperature measured from absolute zero.
|
| A method of measuring viscosity using the poise as the basic measurement unit; this method utilizes a partial vacuum to induce flow in the viscometer.
|
| 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, it is the actual volume occupied by the different ingredients determined by dividing the weight of each ingredient in pounds by its specific gravity times the weight of one cubic foot of water in pounds; example. the absolute volume of one sack of cement equals 94 divided by 3.15 times 62.4 equals 0.478 cubic feet.
|
| A theoretical lowest possible temperature, at which all molecular motion ceases, calculated to be exactly minus 273.15°Centigrade or minus 459.67° Fahrenheit.
|
| To swallow up or suck in, like wood absorbing a finishing material.
|
| Moisture that has entered a solid material by absorption and has physical properties not substantially different from ordinary water at the same temperature and pressure; in aggregates, that water which is not available to become part of the mixing water.
