ASTM C822-08a

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

2. Terminology
absorption—the increase in weight of concrete resulting from the penetration of water into the concrete.
absorption test—a test made to determine the absorption of concrete.
admixture—a material other than water, aggregates, cement and fibre reinforcing used as an ingredient of concrete and added to
the batch immediately before or during its mixture.
annular space—the space between the inner surface of the female end and the outer surface of the male end of an assembled pipe
joint.
bell—see female end of pipe.
blend—a combining of various cementitious materials.
box section—a concrete pipe with a rectangular cross section.
box section bottom slab—lower horizontal portion of a box section in the installed condition.
box section top slab—upper horizontal portion of a box section in the installed condition.
box section wall—vertical sides of a box section in the installed condition.
cage—an assembled unit of steel reinforcement consisting of circumferential and longitudinal bars or wires.
circular reinforcement—a circular-shaped line of reinforcement.
circumferential reinforcement—reinforcement that is approximately perpendicular to the longitudinal axis of the concrete pipe,
box, or box. structure.
combined sewer—a pipeline intended to convey sewage and storm water.
compression test—a test made on a concrete specimen to determine the compressive strength.
compressive strength—the maximum resistance of a concrete specimen to axial compressive loading; or the specified resistance
used in design calculations.
concrete—a homogeneous mixture of portland cement, fine aggregate, coarse aggregate, and water. The mixture may also contain
admixtures, or other cementitious materials, or both.
core—a cylinder of concrete obtained from concrete by means of a core drill.
crown—the top or highest point of the internal surface of the transverse cross section of a pipe.
culvert—a pipeline intended to convey water under a highway, railroad, canal, or similar facility.
cylinder (test)—a cast cylindrical specimen of concrete.
design strength—the minimum acceptable 0.01-in. (0.3-mm) crack D-load.
designated size—the dimensional name for a particular size that may or may not be equal to or related to the dimensions used
for design purposes or of the manufactured product.
distribution reinforcement—reinforcement, typically running 90° to the main or circumferential reinforcement, intended to
disperse concentrated loads to larger areas of a structural member.
D-load—the supporting strength of a pipe loaded under three-edge-bearing test conditions expressed in pounds per linear foot per
