The M112 demo block is made of which explosive material?

The M112 demo block is made of Composition C-4, which is a plastic explosive composed primarily of RDX (Cyclotrimethylenetrinitramine). Composition C-4 is specifically designed for demolition purposes due to its stability, ease of handling, and high energy output. It is widely used in military applications for breaching operations or demolition tasks.

The key characteristics of Composition C-4 include its low sensitivity to shock and friction, making it safe to handle compared to other explosives. Additionally, its high detonation velocity ensures effective performance during demolitions. The material can easily be shaped or molded to fit specific tasks, enhancing its versatility in various operational scenarios.

While other explosives like Composition B, TNT, and RDX have their unique applications and properties, they do not match the specific formulation and intended use associated with the M112 demo block, which is explicitly made with Composition C-4 due to its desirable properties for military demolition work.
