“…The mechanical properties of the porous ceramics were improved with the increase of forming pressure, indicating that the forming pressure was beneficial to increase the contact area between desert sand particles and form a large area of glass connection, thus improving the mechanical properties of the ceramics (Fig. 8b) [20]. In 13 addition, bending strength is related to the grain size of sand particles acting as the skeleton support in the ceramic.…”

Desert sand has the characteristics of large reserves, high quartz content, small and uniform particle size, low organic content and so on. High performance porous ceramic materials were prepared by particle stacking from Kubuqi desert sand, and the effects of forming pressure, holding time and sintering temperature on phase transformation, microstructure, sintering properties, mechanical properties and thermal conductivity of ceramics were investigated. The results show that the high temperature melting of feldspar phase in desert sand binds the quartz particles together to form a stable porous structure ranging from several microns to hundreds of microns, and the decomposition of ferric oxide leads to the formation of closed

“…As can be seen in the scientific literature, the thermal properties of bricks was optimized by increasing the volume of cavities, by changing the cavity geometry or the profile of exterior surface [26][27][28][29], and by filling the cavities with different thermal insulation materials [30][31][32][33][34]. Another solution studied and adopted for ceramic product optimization in terms of embodied energy or thermal performance was the incorporation in the clay matrix, organic or inorganic waste [35,36], resulted from different activities.…”

Masonry units made of clay or Autoclaved Aerated Concrete (AAC) are widely used in constructions from Romania and other countries. Masonry units with superior mechanical and thermal characteristics can improve the energy efficiency of buildings, especially when they are used as the main solutions for building envelope construction. Their production in recent years has increased vertiginously to meet the increased demand. Manufactured with diversified geometries, different mechanical and/or thermal characteristics have a high volume in the mass of the building and a major influence in their carbon footprint. Starting from the current context regarding the target imposed by the long-term strategy of built environment decarbonization, the aim of the paper is to analyze the potential of reusing mining waste in the production of masonry units. Mining waste represents the highest share of waste generated at national level and may represent a valuable resource for the construction industry, facilitating the creation of new jobs and support for economic development. This review presents the interest in integrating mining wastes in masonry unit production and the technical characteristics of the masonry units in which they have been used as raw materials in different percentages. Critical assessment framework using SWOT analysis highlights the key sustainability aspects (technical, environmental, social, economic) providing a comprehensive and systematic analysis of the advantages and disadvantages regarding the integration of mining waste as secondary raw materials into masonry units production.

“…The type, fraction and dimensional features of the pore former determine the size, shape, structures and amount of porosity in the synthesized porous ceramic. Some of the recent trends focus on using food, agricultural and industrial waste as pore former (Salleh et al 2021;Dele-Afolabi et al 2017). The pore former candidates from this category is lucrative to be used in the process of producing porous ceramics because its use in this industry reduces the possibility of it ending in the landfill and thus polluting water, air and land.…”

This chapter explored the synthesis method of macro porous ceramic by using the partial sintering, direct foaming, replica template and sacrificial template technique. The focus is to produce macro porosity in the ceramic for specific application purposes that required this porosity range. At first, fundamentals in each technique were discussed and the advancement in the topic for the recent five years was presented. This is followed by advantages and limitations existing with the current technology for each synthesizing technique. Finally, the chapter covers the possible future trends that can be explored in making the process of synthesizing macro porous ceramic to be more repeatable, stable and sustainable in the near future.
