The program on ready-mix mortars, a comparatively new development in the U.S., drew exceptional interest from Conference attendees. The speakers pointed out that this mortar batching system has been in use in Germany, where it was developed, for about 20 years. In 1985, almost 50% of all masonry mortars used in Europe were ready-mix, they said. The material can be delivered in special mortar containers or by ready-mix truck, if the mixing procedure is carefully observed.
In the U.S., a task group under ASTM Committee C12.03, Specifications for Mortar for Unit Masonry, has been working since the latter part of 1983 to develop a new ASTM standard for ready-mix mortars. It appears that a final specification will be completed for ASTM adoption in 1987.
Metal Corrosion Problems Explored
Mario Catani gave an in-depth presentation on metal corrosion in joint reinforcement. Adequate "cover," he said, helps to prevent rust and failure of the reinforcement. He recommended using as much cover on exterior wire as possible, and to use steel with protective coatings such as hot-dip galvanizing or stainless steel, although the cost of the latter could be prohibitive on some jobs.
Catani felt that mason contractors should be more concerned with corrosion and suggested the following:
* Avoid using steel with "mill galvanizing" because it is mainly "cosmetic" and offers very little protection.
* Wire that is completely embedded should have an ASTM Class I coat: Class III should be used for non-embedded steel.
* Use non-chloride, non-corrosive accelerators for cold weather construction (calcium chloride encourages corrosion).
The workshop on forklift maintenance featured a narrated slide show and a visual demonstration of lift trucks in the hotel parking lot by two representatives of Lull Engineering Co. and JCB, both major manufacturers of this type of rough terrain equipment.
Clifford Fay of MCAA's independent auditing firm, Fay, Conmy & Co., presented the final workshop of the day on financial planning.
Five committee meetings and an MCAA Executive Board Meeting were held Sunday morning, March 2, with the rest of the day open for fishing, sailing and visiting the sights of St. Petersburgh Beach.
The evening was capped off with a gala reception for MCAA members sponsored by Lone Star Industries, Inc. in the Pavilion and Ballroom areas of the TradeWinds.
Monday, March 3, it was back to business again with the Opening Session of MCAA's '86 Educational Confer-
