Modification of Brick Loams with Multi-Layer Carbon Nano-Tubes for Production of Wall Ceramics
The technology of the modification of clayey raw material with multi-layer nano-tubes is proposed as an alternative to the modification of brick loams with plastic clays. The technique oftheir introduction in the composition of clay mass in the form of dispersions in surfactant solutions is considered. The micro-structure of an adobe and ceramic body in the presence ofan optimal amount of a nano-modifier was studied. The practical application of the proposed technology makes it possible to abandon the development of several quarries by enterprisesin favor of more technological modifying additives, reduce the load on public roads and improve the region ecology. Results of the industrial approbation of developed recommendationswhen producing the ceramic whole brick are presented. The technical effect is in improving drying properties, reducing the time for adobe draying, improving the appearance andimproving operational indicators of wall ceramic when using small amounts of modifying additives.
