“…But when we check the chemical composition and chemical characteristics of fly ash, it is clear that it has some cementing property. So, it can be used as a cementing material in concrete [4]. Through this study, we can examine the differences between ordinary concrete mix and rubberized concrete mix in terms of various strengths.…”

Waste tyre disposal is one of the biggest environmental problems the world is currently experiencing. Because of its non-bio degradable character, it is very difficult to dispose them without making much harm to the environment. So, there is a big need of finding out a new way to dispose the tyre waste safely. Use of tyre rubber in place of fine aggregate in construction field was one of the alternatives put forth. An investigation in the compressive strength of concrete having shredded tyres in place of sand was conducted through an experimental program. For this investigation, several cubes, beams, and cylinders of M30 grade were cast. The fine aggregate in concreter mix were replaced with 20%,25%,30% of tyre rubber. As we all know that, that, there are numerous thermal power plants across the world, each plant produces different kinds of waste materials like fly ash, its disposal also needs some serious supervision. Due to the presence of some chemical’s like calcium oxide, fly ash can be used as a cementing material. This experiment studies the characteristics of tyre rubber induced concrete and check the feasibility of replacing cement with 25% of fly ash in that rubberized concrete mix.

“…Reactivating cement involves using leftover or waste cement in new construction projects instead of producing new cement from raw materials, thereby reducing the construction industry's carbon footprint, conserving natural resources, and minimising waste [10], [11]. There are several options for recycling cement and concrete, including using them as aggregates [12], [13] in new concrete production, using them as binders [9], [14], [15], and using them as raw materials in the production of blended cement [16]- [19].…”

Over the last decade, research has increasingly focused on reducing the use of natural resources and improving waste management in the construction industry. Various possibilities exist for reducing waste in this sector, ranging from using waste as filler materials to developing new binders and building materials. This study focuses on the development of bio-based building materials using waste from the manufacturing of wood-wool cement boards. The binder and filler materials were obtained from the manufacturing waste and used in this research. The developed materials were tested for their visual appearance, macrostructure, material density, thermal conductivity coefficient and compressive strength. The results showed promising data for the self-bearing bio-based building materials, which had similar thermal properties to other bio-based materials and could be used as thermal insulation materials with a thermal conductivity coefficient of 0.0827–0.1172 W/(mK). The material density of the developed bio-based composites was found to be 430–617 kg/m3. By incorporating manufacturing waste into the production process of bio-based building materials, it becomes evident that overall waste from manufacturing plants can be significantly reduced, and the sustainability aspect of wood-cement board manufacturers can be enhanced.

“…The research showed that concrete consisting of a mixture of two types shows mechanical, physical, and geometric properties and a decrease in the modulus of elasticity and compressive strength similar to recycled aggregate. CH Karthik and A Nagaraju [32] with adopting a fly ash and alccofine, this paper's primary goal is to determine the strength characteristics of recycled aggregates' in order to utilize them as a sort of substitute for natural aggregates. Madhu, K. A., et al [33] with three cycles of demolition waste aggregate and 25%, 50%, 100% percentages as coarse aggregate and to achieve long sustainability, the research concentrated on the use of concrete demolition waste.…”

One of the most significant environmental issues worldwide is garbage, particularly waste from construction materials, which is generated in substantial numbers. However, in the building industry, the significant extraction of natural resources such as cement, natural sand, and natural gravel poses a critical environmental challenge, depleting these resources at an alarming rate. There are some solutions that developed countries are resorting to, namely the division of construction waste into groups, where it is reused under the name of recycling construction waste to produce new, environmentally friendly building materials. The aim of this research includes a laboratory process study as it includes the use of the following ratios: 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100%, under the process of replacing coarse plain aggregates including coarse recycled aggregates and studying the most important mechanical properties of concrete. This research was carried out using fresh concrete properties such as workability tests and hardened concrete properties such as compressive strength, splitting, and flexural tensile strength examined at the durations of 7, 14, and 28 days. The research includes the investigation of the three main properties of concrete. After conducting the tests, the results have shown that the main property of recycled concrete is lower strength than that of conventional concrete, but it can be said that it is within the limits that can be used for construction. The results also showed that compared to normal aggregates, development in the recycled aggregate percentage rates reduces the operational workability of concrete. The research proved that the maximum decrease in compressive, flexural, and tensile strength, density and the slump were 19.4, 18.3, 19.6, 19.5, and 25.0% respectively compared to the control concrete samples.
