Kantro, D. L.

Progress in research on potential alternatives to gypsum for controlling set in commercial concretes, additives to deter sulfate-induced expansion, and the influence of clinker manufacture on expansion potential in cements is reported. The purpose of these studies is to show that if limitations on sulfur content could be made less restrictive, it should prove possible to use kiln fuels with higher sulfur contents and to employ energy-efficient modern preheater kiln technology without risk of exceeding sulfate specifications in the finished product. The use of high sulfur fuels is desirable in that it allows high quality, low sulfur fuels to be reserved for key applications where substitution is technically impossible. The use of modern kiln technology is desirable from the point of view of saving energy. (LCL)
