“…The unfired bricks developed through the geopolymerization process mainly influence the material composition and pore structure formation through the hydration process, causing various effects of vapor and chemical composition-based heating [108]. As a result of heat transfer mainly influences the pore pressure increase gradually upon pore structure, He et al [109].…”

Use of bricks and their manufacturing process plays an important role in the construction sector. Despite its various methods of manufacturing, still large quantities of bricks are used in the building construction. Manufacturing of bricks consumes large quantities of natural resources, and it is energy intensive. Similarly, due to rapid industrialization large quantities of waste industrial byproducts are generated and causes handling and disposal challenges of these wastes. This review work attempts the possibilities and potential use of various types of waste industrial byproducts in fired and unfired bricks. This study also highlights the importance of waste and its usage guidelines in bricks manufacturing to enhance the strength and durability properties. To overcome the challenges associated with bricks manufacturing, firing is still considered as the most preferred method of making bricks. Use of industrial waste byproducts to the mix matrix of fire and unfired bricks will overcome the disposal challenges and reduce the depletion of natural resources. Since sustainability is a key factor that is considered when it comes to making bricks, innovative methods are needed to produce them using sustainable materials. The production and application of bricks and their usage guidelines are reviewed further in various aspects such as environment, social, economic, and technology to meet global standards and policies of the local government for sustainable development.

“…As a result, substitute materials have shown a successful performance, creating significant potential in the production of a sustainable geopolymer. Kim Hung Mo and Tung-Chai (19) investigated the influence of fly ash and bottom ash on the production of bricks and blocks. The test findings indicated that the bottom ash has the potential to serve as an aggregate, effectively reducing the density and thermal conductivity of bricks and blocks.…”

Objectives: The production of conventional cement blocks consumes significant amount of cement. The production of cement, involves significant energy consumption and releases carbon dioxide emissions, contributing to carbon footprint. However, advancements in sustainable masonry block production have been made to minimize these drawbacks. Hence, this research aims to develop a sustainable masonry solid block by incorporating Rice Husk Ash (RHA) and Flay Ash (FA). Methods: The manuscript discusses the mechanical and durability properties of sustainable masonry block and comparing the result with the conventional cement blocks. The materials used are FA, Lime, Gypsum, RHA, Marble Dust Powder (MDP), Stone Quarry Dust (SQD). The solid blocks tested for Compressive strength, Density, Water absorption, Initial rate of water absorption, efflorescence, and chemical resistance. Findings: The results showed that, the addition of RHA, FA, and MDP enhanced the compressive strength of the solid blocks upto 46% when compared to convention cement block. A density reduction of 2.5% was achieved. It also exhibited a reduction in water absorption of 29.2%. IRA tests evident that the sustainable solid blocks shows reduced water absorption levels at both the one-minute and two-minute time intervals in comparison to conventional cement solid blocks. At a one-minute time, the rate of absorption for M4 is 69% lower when compared to conventional cement solid blocks. The RHA, FA and MDP admixed blocks showed better durability properties in terms of efflorescence, and chemical resistance. Novelty : This solid block production method is an innovative methodology that supports the conservation of natural resources, reduces pollution, and preserves the environment. As a result, it encourages the advancement of eco-friendly technology. Keywords: Sustainable building blocks, Fly ash, Lime, Rice husk ash, Marble dust, Stone quarry dust

“…Currently, CFA is used mainly as building material in the cement and concrete sectors and as soil stabilization for roads, embankments and ash dyke raising, landfill liners or covers, in mine filling, in bricks, blocks and tiles, agriculture, and others [ 6 , 7 , 8 ]. However, these applications reduce solid waste but do not fully exploit the potential uses of this rich resource [ 9 , 10 ].…”

The article presents studies of the influence of parameters of synthesis modes and alkali concentration on the synthesis of zeolite materials from coal fly ash (CFA). The purpose of the study was to synthesise zeolite materials from CFA using the method of alkaline fusion and to determine the susceptibility of selected heavy-metal ions to removal from solutions in an ion exchange process on a selected mesoporous zeolite. It was found that the crystalline phase of sodalite was dominated in all of the samples synthesized. The specific surface area (SBET) of the samples was evaluated using the standard Brunauer–Emmett–Teller (BET) method using N2 sorption. Crystalline zeolite materials have been used to study the efficiency of removing heavy metals from aqueous solutions of Ni2+, Cd2+ and Pb2+. The adsorption data were analyzed using the Langmuir and Freundlich isotherm model. When comparing the estimated coefficient of determination (r2), it was noticed that the sorption data are more accurately described by the Langmuir isotherm and the pseudo-second-order kinetic model. The results of metal adsorption experiments suggest that the synthesized zeolite material has great potential to be used as an inexpensive and alternative source in the production of adsorbents.
