CVE 474 Construction Materials/ Concrete Lab Experiment #2: Brick/Concrete Masonry Unit Properties 4/12/2011 Jonathan Brate Abstract: This report describes the four part procedure that was performed to become familiar with the physical properties of brick, learn ASTM standards, and perform standard ASTM tests on masonry units. The procedure includes initial rate of absorption for oven dry brick, moisture

conditions of brick, flexural test of brick, and compressive test of brick. Properties measured include gross area, net area, net volume, gross compressive strength, net compressive strength, absorption, absorption percentage, saturation coefficients, and dry density. The properties are important to record and understand because they directly relate to the strength and durability of the brick.

Part I was performed according to ASTM C67 standards. First, the three brick’s dry weights and dimensions were recorded. Second, each brick was submerged in water for 60 seconds and then weighed again to acquire the 60 second wet weight. Last, the initial rate of absorption in 1 minute was calculated. Original documentation can be found in Appendix A.
