Testing Of Missouri Shales For Light Weight Aggregate Production, Jerry D. Plunkett
Testing Of Missouri Shales For Light Weight Aggregate Production, Jerry D. Plunkett
Masters Theses
"The original objective of this investigation was to determine by testing those clays, shales, and loesses occuring in Missouri in large deposits (over 15 feet in thickness with little overburden), which would be suitable for the production of light weight aggregate. The second objective was to investigate the mechanism of bloating as related to the physical and chemical properties of the above materials, and by using these relationships cause clays which do not naturally bloat, to bloat using some addition. The use of additives would permit the economical use of material closer to the market in many instances.

The Bloating Of Missouri's Shales, Peter Kurtz Jr.
Masters Theses
"The first objective of this investigation was to determine which deposits of clays, shales, and loesses in Missouri are suitable for use in the production of lightweight aggregate by virtue of their expanding characteristics upon heating. The second objective was to determine, if possible, commercially feasible additions that will produce the bloating property in shales that do not naturally bloat.
There are two conditions which must be met in firing in order to bloat a clay or shale. First, a gas must be formed and evolved during firing. Second, enough glass of the proper viscosity must be formed to trap …
