Principles for creation of optimal structures of ceramic semidry pressed brick

The principles for creation of optimal structures of ceramic semidry pressed brick are formulated. It is found out that for low- and moderate-plasticity clay raw material its refinement to class -0.3+0 mm is required. Best grain packaging of the grinded fine raw material during compaction is achieved due to its preliminary aggregation. It is established that the rational granulometric composition of a press powder is ensured by material granulation in the turbo impeller mixer-granulators. Experimentally and in the industrial conditions it is confirmed that the bricks produced from fine grinned granulated material has a uniform, defect-free texture of s ceramic crock, providing an increase (in 1,3–1,5 times) in physical and mechanical properties of products. A new method for obtaining an effective wall ceramics with uniformly distributed system of freeze resistant macropores incorporated into the wall waterproof glass crystalline framework formed on their surface is offered.
