Initial Rate of Absorption of Clay Brick Considering Both Bed Surfaces in the as Received Condition and After Outside Exposure

Source

The initial rate of absorption test (suction) on a clay brick unit is generally conducted in the laboratory according to ASTM c-67. This test attempts to represent the effect of the unit on pulling water out of the mortar during assemblage construction. In ASTM C-15 committee work, two questions that have been raised are: 1) Is the IRA of a unit the same for both bed surfaces that will be in contact with mortar? 2) When as received units are exposed to typical Texas heat, is the IRA significantly affected?

To address these questions a project was conducted at The University of Texas at Arlington. In addition data was requested and received from various U.S.A. brick manufacturerers. Analysis of this data provided answers to the above questions.
