The issue studies the use of nanotechnology to improve the various properties of clay bricks to obtain improved bricks that we can use in various industries. Brick is a natural building material used in construction. It is usually made from clay, sand and water, drying them in the sun and then it goes into the oven to burn. Because the thermal conductivity of the brick is defined as the amount of heat flow through a unit area, in a direction normal to the surface area, with a known temperature gradient, thermal conductivity depends on the chemical and mineralogical composition of the clay material. The high thermal conductivity of a brick is desirable when heat transfer through brick is required, for example in recuperators, regenerators, muffles, hot blast stoves, coke ovens, etc. Therefore, improving the thermal conductivity of bricks is of great importance to the realization of energy saving and emission reduction in the iron and steel industry.

Thermal conductivity of bricks is of great importance to the realization of energy saving in industry. The primary goal of this special issue is to improve thermal properties of clay bricks. We invite contributions that explore clay brick industry, with particular interest in using nanomaterials.

Through this special issue, we aim to Obtain new and different ways to maximize the benefit from using clay bricks and nano materials together. We welcome researchers from various disciplines to provide interdisciplinary perspectives. Your contributions will play a crucial role in advancing knowledge in this field.
