Abstract:

This specification covers the standard guide for welded deformed steel bar mats for concrete reinforcement. Mats should be capable of withstanding static load exerted perpendicular to the plane of the mat tending to separate the bars with no apparent loosening when applied to one intersection of the connected bars. Tension tests shall be performed on the specimen to determine the conformance to reference test materials. Also, test of connections against separation shall be performed on an assembled mat by placing blocks under a deformed bar in the upper layer and applying the prescribed load upon the bar in the lower layer.

Scope:

1.1 This specification covers material in mat (or sheet) form fabricated from deformed steel bars to be used for the reinforcement of concrete. Mats consist of two layers of bars that are assembled at right angles to each other. Mats are assembled by welding at the intersections.

1.2 This specification is applicable for orders in either inch-pound units (as Specification A184) or SI units (as Specification A184M).

1.3 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
