Brick Manufacturers
(Continued from page 25) provide more technical assistance to engineers and architects.
Presentations to the more than 700 persons attending the convention were made by William S. Lowe, president of the U.S. Chamber of Commerce, and Dr. Rodolfo J. Aguilar, professor of engineering at Louisiana State University.
Lowe urged the manufacturers to become more involved in the affairs of their communities and to make a special effort to sell capitalism and free enterprise to young persons. Aguilar, who is also president of ADH Systems, Inc., a Baton Rouge real estate development organization, described an approach to construction that allows developers to build with only minor capital outlays on their part.
William S. Jones of Pleasant Garden, N.C., was elected president of BIA. He succeeds Charles T. Richards of Edwardsville, III. Jones is president of Boren Clay Products Co.
Elected vice president was William G. Temple, president of Denver Brick & Pipe Co., Denver, Colo. Joseph H. Patrick, president of Southern Brick Co., Inc., Ninety-six, S.C., was re-elected treasurer.
Weaker Brick Can
Make Stronger Masonry
The compressive strength of brick masonry is significantly increased by an increase in the height of brick units, as indicated by the result of a research project conducted by Dr. James Houston and Clayford T. Grimm in the College of Engineering at the University of Texas at Austin.
Although the compressive strength of brick was found to decrease with increased height of the unit, the compressive strength of brick-mortar assemblages was discovered to increase as the height of brick increased.
A literature search indicates that Houston and Grimm are probably the first to discover this relationship. Prisms built of 3% in. high brick were found to be nearly 50% stronger in compression than prisms built of 1% in. high brick, and about 23% stronger than those built of standard modular brick, having a height of 24 in.
For a given mortar joint thickness the quantity of mortar in masonry is reduced as brick height is increased. Because mortar is typically considerably weaker than brick and because of the failure mechanism of masonry, higher brick produces stronger masonry.
