Brick Test Durham NC

I have received test data from the manufacturer of the brick I selected for a new building. How do I read the test data? What is important and what isn't important? There are several items that I would examine on the brick test data in Durham.

I have received test data from the manufacturer of the brick I selected for a new building. How do I read the test data? What is important and what isn't important? There are several items that I would examine on the brick test data. In freeze/thaw environments the units should be Grade SW. A Grade SW brick must have an average maximum cold water absorption of 17% with a maximum individual value of 20%. The maximum average saturation coefficient is 0.78 with the maximum individual value of 0.80. Saturation coefficient is sometimes referred to as C/B because it represents the ratio of the cold water absorption divided by the absorption after 5 hours of boiling. In areas not normally subjected to freeze/thaw deterioration, Grade MW bricks can be used. The above values are increased for MW brick to an average maximum absorption of 22% and maximum individual value of 25% and an average maximum saturation coefficient of 0.88 and a maximum individual value of 0.90. The saturation coefficient can be waived if the average cold water absorption is less than 8% with at most one unit between 8% to 10%. The requirements for both water absorption and saturation coefficient can be waived if the units pass the freezing and thawing test described in ASTM C 67.Minimum compressive strength values also are set for durability.
