To achieve a good compaction of Thick Layer, Plastic Installations, each clump should be?

To achieve a good compaction in thick layer plastic installations, each clump should be consolidated into a uniform mass. This is important because effective compaction ensures that the refractory material forms a solid, dense structure, which is crucial for the performance and durability of the installation.

When the clumps are consolidated, they interlock and fill any voids, minimizing air pockets that could weaken the integrity of the refractory lining. A uniform mass also enhances the thermal and mechanical properties of the material, making it more resistant to stress and wear during service.

In contrast, layering loosely or leaving materials in large chunks would prevent effective consolidation and could lead to areas of weakness or failure in the installation. Mixing with additional water can compromise the material’s properties and lead to issues like porosity or reduced mechanical strength. Thus, consolidating the clumps into a uniform mass is the best practice for achieving a high-quality installation.
