Q.: Does the American Concrete Institute have a promotional program for nonreinforced concrete parking lots?

A.: We do not know of any such program. Perhaps you are thinking of a program offered by the Portland Cement Association. The program provides letters and other promotion aids for mailing as well as a desk-top display that can be used for personal presentations. Details were described in an article on page 279 of the March issue. Further information can be obtained from John Koller, Portland Cement Association, 5420 Old Orchard Road, Skokie, Illinois 60077.
