Development of porous lightweight clay bricks using a replication method

This study focused on porous lightweight clay bricks as a construction material as opposed to autoclaved aerated concrete and pumice blocks. Traditional clay bricks exhibit good stability against environmental conditions and are an economical alternative compared to other construction materials. Furthermore, clay bricks have better mechanical properties than autoclaved aerated concrete and pumice blocks but poorer thermal insulation properties; hence, their use in buildings is becoming increasingly unfavourable. This study focused on developing porous lightweight clay bricks with relatively better thermal insulation properties using a replication method.

Development of lightweight ceramic construction materials based on fly ash

This study aims to demonstrate the suitability of using lightweight ceramics as a construction material in preference to autoclaved aerated concrete and pumice blocks or the more commonly used brick. For construction applications, ceramics show good stability under fatigue loadings and severe environmental conditions and are an economical alternative to other materials. Although bricks have better mechanical properties than the new generation construction materials, thermal insulation properties of brick are much lower. Hence, the use of bricks as a fired construction materials is becoming increasingly unfavorable; as a result, brick manufacturers are losing their market share day-by-day. This study aims to develop an alternative fired lightweight, ceramic construction material with fly ash with relatively better mechanical and thermal insulation properties.

The Effect of Lithium Alumina Silicate Phases on Elastic Modulus of Porcelain Tiles

Spodumene, which is a lithium alumina silicate, has been used as a raw material in the production of thermal shock resistant whitewares and sanitarywares. The presence of spodumene results in enhancement of mullitization and imparts better physical and mechanical properties to ceramics. In this study, the influence of Lithium alumina silicate phases on the mechanical properties of standard porcelain stoneware body was investigated. Especially solid-solid reactions were observed between spodumene and quartz or spodumene and clay. These solid-solid reactions bring about a newly formed lithium alumina silicate (LAS) phases. Spodumene allows the development of a low viscosity liquid phase and results in a decrease in closed porosity, also with increase in bulk density, bending strength and elastic modulus.

The development of porcelain foams lighter than water for heat isolation application

In this study, technological and heat isolation properties of porous ultra-lightweight porcelain foams were investigated. Traditional construction materials such as brick show good durability against environmental conditions. Bricks are also a good alternative compared to pumice blocks and autoclaved aerated concrete which are largely used as construction materials. Bricks are also more economical than the other construction materials. But they also have poorer thermal insulation properties. Among the construction material, XPS shows the best heat isolation properties. XPS (extruded polystyrene foam) is a polymeric material. Although XPS shows best heat insulation property, it easily flames. The aim of this study is developing porous porcelain isolation materials lighter than water by using a replication method and relatively better thermal isolation properties than the other construction materials.
