“…The elevation of the calcite peak is also good evidence for the formation of C-A-S-H gel in the material. In the process of gel generation from this polymer, the main chemical reaction is the reaction of Ca 2+ , Si 4+ , and Mg 2+ in the matrix with OHin the alkali activator as shown in Equations ( 6)- (8).…”

“…In recent years, the rapid advancement of urbanization has led to a sharp increase in building density and land surface coverage, triggering a transformation in the urban surface water circulation system and frequent occurrence of internal flooding [1]. Porous concrete, known for its excellent permeability and drainage capacity [2][3][4][5], is typically composed of cement mortar and aggregates and widely applied in areas such as parking lots, permeable road surfaces, and riverbank slopes [6][7][8][9][10]. With its unique porous structure, porous concrete plays a crucial role in mitigating urban flood risks and alleviating the urban heat island effect [11,12].…”

Red mud (RM) and Yellow River sediment (YRS) are challenging to handle as waste materials. In this study, RM with geopolymer and heavy metal adsorption characteristics was combined with YRS and ground granulated blast furnace slag (GGBS) to develop a porous geopolymer with high strength and high adsorption performance. A geopolymer cementitious material with high strength was prepared using high temperature water bath curing of 90 °C and different dosages of YRS, and a porous geopolymer concrete was further prepared. The compressive strength, fluidity and setting time of geopolymer cementitious materials were tested, and the compressive strength, porosity and permeability of porous geopolymer concrete were also tested. The environmental impact assessment of geopolymer cementitious materials was further conducted. The hydration products and microstructure of geopolymer gel materials were analyzed by XRD, SEM and FT-IR tests. The results show that the addition of YRS can effectively prolong the setting time of the geopolymer cementitious material, and the enhancement rate is as high as 150% compared with the geopolymer cementitious materials without the addition of YRS. An appropriate amount of YRS can improve the compressive strength of the geopolymer cementitious materials, and its early compressive strength can be further improved under the high temperature water bath curing of 90 °C, and the compressive strength at an age of 3 d can be up to 86.7 MPa. Meanwhile, the compressive strength of porous geopolymer concrete at an age of 28 d is up to 28.1 MPa. YRS can participate in geopolymer reactions, and high temperature water bath curing can promote the reaction degree. Curing method and YRS dosages have little effect on the porosity and permeability of the porous geopolymer concrete. The porous geopolymer has a good heavy metal adsorption effect, and the alkaline pH values can be gradually diluted to neutral.

“…This is dependent on the fibre type in composite designs. For example, Bagaria and Juneja [31] discovered that a maximum of 16% SF is mechanically viable with 0.8% polypropylene fibres. This is because the adhesion between the fibres and the matrix can vary, creating voids surrounding the interfacial zone of the fibre.…”

The building and construction industry heavily relies on the use of concrete and cementitious composites due to their exceptional attributes, including strength and durability. However, the extensive use of these materials has led to significant environmental challenges, including resource depletion, carbon emissions, and waste accumulation. In response to these challenges, recent advancements in fibre cementitious composites have shown promise in mitigating these detrimental effects. The integration of waste materials to supplement manufactured fibres represents a promising development in reinforced concrete composite materials. Waste materials like textiles and cardboard are emerging as potential fibre supplements in cementitious composites. While these materials have primarily been investigated for their mechanical characteristics, understanding their thermal properties when applied in construction materials is equally crucial. Incorporating fibres within composite designs often requires matrix modification to reduce degradation and enhance fibre longevity. This study aims to investigate the thermo-phase change properties of both textile and cardboard fibres within varied concrete matrices. Additive materials offer a range of advantages and challenges when used in composite materials, with additional complexities arising when incorporating fibre materials. Understanding the thermal reactivity of these materials is crucial for optimizing their application in construction. This study demonstrates the potential of waste fibres used with gypsum, metakaolin, and silica fume as matrix modifiers in concrete. This research provides valuable insights for future studies to explore specific material combinations and investigate complex fire testing methods, ultimately contributing to the development of sustainable construction materials.

“…Additives such as superplasticizers and pozzolanas are typically used in the mixture to improve the physical properties of the finished product or the wet mix. Reinforced concrete is created by pouring most concrete with reinforcing components like rebar inserted to enhance tensile strength [4]. From 45-65% of commercial structures in nations that are developing have marble floors.…”

The study focuses on the conservation of natural resources by replacing three vital construction materials: (i) Ordinary Portland Cement (OPC) with Marble Dust (MD) (ii) Fine Aggregate (FA) with tile in powdered form and (iii) aggregate with tile chips (TC) for the building construction works. In this present study, the abovementioned materials were used in 10, 20, and 30% as a replacement. As per the current scenario, only limited research papers are available that show what happens when the components are used as individual substitutions for the materials. Due to the lack of supporting evidence for material substitutions in concrete construction, the philosophy of experimenting with the use of mixtures of substitute materials in concrete has emerged. Experiments were conducted with M25 grade concrete, and the best mixes, M24 and M32, are mixes that replace all three traditional components of concrete, achieving strengths of 31.11, 2.76, and 8.0 N/mm2 in compression, 33.33, and 2.76, and 8.25 N/mm2 in flexure, respectively.
