THE HIGH BOND CLASSROOM
a monthly feature by Amspec
This whole idea of a monthly article to discuss the high bond masonry revolution came to us soon after the June issue of MASONRY was published. Oh, we had thought about ways to share all of our hard-gained knowledge and technology with you masonry contractors. Thought about it for more than a dozen years, in fact. We even did something about it, with seminars and workshops and head-to-head confrontations with masonry contractors all over the country.
But it wasn't until after MASONRY Magazine came out with that June issue that we really went to work. An article in the magazine -"Revolutions in Masonry Today," by Dallas Grenley, Research Chemist for The Dow Chemical Company-provoked a good bit of response from you people.
We discovered something we already knew-but perhaps didn't realize fully. You masonry contractors want straight answers, good advice, practical suggestions. In short, you are interested in keeping up with or a little ahead of the rapid advancement of the masonry business.
Constant improvements are taking place in such fields as high strength mortars, epoxy mortars, brick manufacturing, prepared mortars, winter construction, material handling equipment and brick and block masonry design. You must now be expert in finance, management, architecture, labor relations and computer programming, not to mention your basic responsibility to keep up with the ever-changing technology of your industry.
But where can you go for this knowledge? How can you stay on top? You could spend weeks looking for the answers to questions like: What makes high bond mortars set up harder? What ASTM tests really determine quality control? What sand is best for your needs? What can you do to compete with concrete and metal "Systems" builders?
The Dow Chemical Company has been working on answers to these questions since 1957. It was at this time that SARABOND brand high bond mortar additive was being developed. SARABOND is a SARAN polymeric emulsion specifically designed to be added to portland cement mortar systems to improve the structural properties of brick masonry mortar. Because SARABOND could not be used with the available prepared mortars, a new mortar had to be developed. Years of research on mortars and brick were devoted to your masonry industry.
To expand their knowledge of mortars, The Dow Chemical Company began investigating epoxy mortars for concrete block construction. THREADLINE brand adhesive mortar was found to be the best possible combination of epoxy, hardener, resin, portland cement, and polymeric emulsion for use with concrete masonry. This was the only material which combined strength, economy, ease of application and ease of clean up. This toothpaste-like adhesive mortar is applied with a caulking gun and cleaned up in water. The production is usually double that of conventional mortar and the bond strength is four times greater. No other epoxy or thin bed mortar can boast the success story of THREADLINE.
Why haven't you heard about all this research? Because no one knew you gave a damn, until we saw your interest in the high bond masonry revolution.
So stand prepared for some hard hitting facts about your business. In coming issues we'll be discussing such topics as: Mortar Color and how to maintain consistent color in masonry mortar, Special Additives, including lime, limestone, soaps, clay, and other workability formulas: Waterproofing Agents; Cement Types and how they affect your mortar: Special Brick; Masonry Cement: Epoxy Mortars: Panelization with high strength mortar; and many other topics.
We think that we can help you to keep on top in your business. That's the reason for this brand new monthly article. We want to work with you. Every month we'll be discussing things you want to know more about. In fact, we hope you'll send us questions, and suggestions... even your own answers. This way we'll be able to make this article work even harder for you.
And that's what we want.
