Seminars Promote Masonry In Chicago
In Chicago, the cooperation of all aspects of the masonry industry has resulted in successful promotion programs that cover the entire Metropolitan area. Their most recent project, Architectural and Engineering Seminars held on two successive days (September 30, 1975 and October 1, 1975) at the Hyatt Regency Chicago Hotel, told the masonry message to 300 area architects and over 100 design engineers. This kind of exposure to construction decision-makers can come only from the combined efforts and dollars of many segments of our industry. Under the umbrella logo of Metropolitan Chicago Masonry Council, nine bricklayer unions, five mason contractor associations, brick manufacturers, brick distributors, concrete block producers, and many allied interests (such as cement and lime makers, construction equipment firms, etc) brought in top technical speakers to present the many advantages of masonry wall systems.
Update... 75, an Architectural Seminar on masonry wall properties, covered fire ratings and protection, masonry loadbearing design, energy conservation, hi-rise amendments to the Chicago Building Code, and the film "Noise Control with Masonry". The Architectural Seminar also featured the grim documentary "Incendio" (produced by the National Fire Protection Association in cooperation with the U.S. Bureau of Standards). This film depicts the Joelma Building fire in Sao Paulo, Brazil, in which 179 persons died in a fire that raged through the upper half of a 25-story, reinforced concrete frame office building.
Titled A "New" Consideration in Structural Design, the Engineering Seminar told how modern loadbearing masonry wall systems can cut down on both time and money in building construction, and covered technical questions on the design and construction of this system from single-story buildings through hi-rise.
Primary speakers at both seminars were Alan H. Yorkdale, P.E. (Director of Engineering, Brick Institute of America, Washington, D.C.) and Thomas B. Redmond, P.E. (Manager of Research and Development, National Concrete Masonry Association, Washington, D.C.). Speaking at the Architectural Seminar on fire protection and hi-rise building code amendments was architect Ed Schultz (Code Consultants, Inc., St. Louis, MO). Additional speakers at the Engineering Seminar were Richard M. Gensert, P.E. (Gensert Peller Associates, Cleveland, OH) and Structural Engineer C. Gregory Veith (Wiesinger Holland, Ltd., Chicago).
AT LAST... there's a concrete & masonry pump you can FINE TUNE to the job. Thomsen's Adjusta-Mix AZM
PICK A JOB: Load-bearing walls (block fill); tunnel grouting; cellular foam concreting: decks: shot-creting; pressure grouting; bond beams; or just plain house foundations and flat slabs each introduces its own variables. Weight; density; air entrainment; aggregate; pressure and more. It takes a very special pump to do its best under all possible combinations of these variables, and the new A7M comes closest to this ideal. The 30-HP A7M (with 4-speed gear box) gives you a choice of speed ranges and torques, and lets you adjust travel of both the 4" feed ball valve and the 4" discharge ball. Simply. In minutes you can balance speed, torque and valve setting for smooth operation and smoother flow at the nozzle. The A7M "Adjusta-Mix" is no pantywaist, and it's a realist! Concrete and masonry are abrasive, so the A7M has a heavily galvanized hopper and hard-chrome cylinders. It has to travel to the job, so it has stable-tow suspension. Mixes and aggregates vary with the job, so the valve adjusts up to %" opening with over 28.8 square inches flow passage. Also, distances, line sizes and heights vary...so the A7M can gear up or down in 4 ranges.
