Loading, by compression

Le Roux (Ref 31) claimed that compns contg phlegmatized RDX and granulated Al are more powerful and possess higher deton velocities than those contg pulverized Al. They can be easily loaded by compression to d s higher than those with pulverized Al. 

The Schneiderite (Explosif S or /Sc) which the French used during the first World War in small and medium-size high-explosive shells, especially in the 75 mm., was made by incorporating 7 parts of ammonium nitrate and 1 of dinitronaphthalene in a wheel mill, and was loaded by compression. Other mixtures, made in the same way, were used in place of Schneiderite or as a... 

It is used in armor-piercing shells as a bursting charge. Ammonium picrate is a salt and does not melt, so it must be loaded by compression. 

Properties Yellow crystals. M. P. 182°. Not very powerful when used alone. Addition of TNT, picric acid, or other nitro high explosives serves the purpose of lowering the melting point os well as that of reinforcement. Mixtures of TNX and ammonium nitrate can be loaded by compression. 

Cast-in joints are typically loaded by compression and bending. Tensile loads should be avoided as the joint length (overlap) and the Joint quality would typically be insufficient.
