“…Therefore, it is preferable to repurpose these materials rather than throwing them away. Recently, waste materials, including fly ash [1] , glass [2] , tires [3] and plastic straws [4] , are being increasingly used in concrete to lower their overall impact on the environment. According to previous studies, it is possible to manufacture concrete using reduced amounts of Portland cement; such concrete has been found to demonstrate satisfactory levels of predicted compressive strengths and enhance environmental performance, making it a suitable replacement for plain cement concrete [4] , [5] , [6] .…”

“…This allows for complex designs to be easily attained, reducing the total construction cost in the process. Future works, including the integration of digital design and construction, robotic manufacturing, as well as sustainable construction like BIM [95,96] 3D printing [97,98], prefabrication [99,100], digital fabrication [101][102][103], innovative material [103][104][105] design for manufacturing and assembly (DfMA) [106][107][108], AI [109,110], sustainable design and materials [111][112][113][114], and machine learning [115][116][117] are valuable tools to predict the design and construction activities accurately and offer sustainable solutions and outcomes. The integration of these tools in the design and construction processes of railway stations is essential to enhance the efficiency and productivity of construction projects while reducing costs and improving the overall quality of the construction projects.…”

An environmentally conscious architectural design of a railway station can have a substantial influence on government spending. Nevertheless, an extensive collection of guidelines for using sustainable design principles in the construction of a railway station can provide several advantages. The goal is to review design visions for railway stations in Thailand, as reflected in student theses and government proposals, from 1983 to 2022 for sustainable design aspects in tropical climates. We perform an analysis of architectural design aspects including service areas, shape, entrances, roofing, style, and development in order to uncover design trends and possible areas that may be enhanced. Station designs are mostly characterized by curved and gable roofs, with 3D curved buildings being the next most common feature. High speed rail (HSR) stations stress local cultural elements in their major entrances while also improving passenger flow. Public buildings frequently employ curved or gabled porticos to achieve a majestic look. Although university theses place a high importance on conceptual design and functionality, it is essential to also consider cost-effectiveness. Key design considerations for future railway stations are transparency, connection, efficient mobility, and cost–time efficiency. The research uncovers deficiencies in user-centered design for thermal comfort and inclusiveness (design-for-all) in Thailand’s tropical environment. Addressing these aspects is critical for future sustainable railway station design evaluations.

“…When burning solid fuel, a large amount of ash and slag waste is generated, the storage of which in ash dumps is a source of soil and groundwater pollution [ 1 , 2 , 3 ] and leads to an annually increasing level of environmental pollution threat. In this regard, the issues of the most efficient use of stored ash and slag waste as secondary resources are relevant today [ 4 ].…”

The Use of Aluminosilicate Ash Microspheres from Waste Ash and Slag Mixtures in Gypsum-Lime Compositions

The article considered the issues of the modification of gypsum stone to improve its performance properties. The influence of mineral additives on the physical and mechanical characteristics of the modified gypsum composition is described. The composition of the gypsum mixture included slaked lime and an aluminosilicate additive in the form of ash microspheres. It was isolated from ash and slag waste from fuel power plants as a result of their enrichment. This made it possible to reduce the carbon content in the additive to 3%. Modified compositions of the gypsum composition are proposed. The binder was replaced with an aluminosilicate microsphere. Hydrated lime was used to activate it. Its content varied: 0, 2, 4, 6, 8 and 10% of the weight of the gypsum binder. Replacing the binder with an aluminosilicate product for the enrichment of ash and slag mixtures made it possible to improve the structure of the stone and increase its operational properties. The compressive strength of the gypsum stone was 9 MPa. This is more than 100% higher than the strength of the control composition of gypsum stone. Studies have confirmed the effectiveness of using an aluminosilicate additive—a product of enrichment of ash and slag mixtures. The use of an aluminosilicate component for the production of modified gypsum mixtures allows the saving of gypsum resources. Developed formulations of gypsum compositions using aluminosilicate microspheres and chemical additives provide the specified performance properties. This makes it possible to use them in the production of self-leveling floors, plastering and puttying works. Replacing traditional compositions with a new composition based on waste has a positive effect on the preservation of the natural environment and contributes to the formation of comfortable conditions for human habitation.
