Aggregates for Concrete

aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-tural lightweight concrete with a freshly mixed density

Carpet Specifications

Pile Density is the key to having a carpet retain its like-new appearance longer. Pile Density ratings range from 1000 to 6000 and is determined using a mathematical formula based on the Pile Height and the Fiber Face-weight. Here is the formula: Fiber Face-Weight x 36, divided by pile height (in decimal form) = Pile Density.
