“…Despite the fact that the mechanical strength fell as the rubber content increased, it should be noted that rubber particles could greatly lower the weight of the material, reduce the rate of water absorption, and improve the insulating aspect of the composite. The study concluded that recycling rubber waste can provide an eco-friendly replacement material [ 14 ].…”

BISCO plaster (BRP) is an environmentally friendly material with high mechanical properties and is considered a great elective to conventional materials such as gypsum and cement. Our investigation seeks to examine BISCO plaster (BRP) and a mixture of resin and hardener in three proportions (30%, 45%, and 60%) to achieve our ultimate goal, which is to preserve the environment and achieve the vision of the Kingdom of Saudi Arabia 2030 to reach zero carbon emissions by 2060? Emissions tests were performed, and although the CO2 level was zero, they emitted SO2 sulfur dioxide and NO2 nitrogen dioxide, and 60% was the lowest emission rate. We also used ANSYS 2023 R1 software to compare them with their mechanical properties resulting from tensile and compression testing. In this study, we looked closely at the mechanical characteristics of different materials designed for wall coverings, with particular emphasis on their environmental sustainability. We carried out experiments to gauge the tensile and compressive stress on samples with varying mixing ratios. Our main objective was on crucial mechanical properties such as the modulus of elasticity, ultimate tensile strength, yield strength, yield strain, modulus of resilience, and ductility. Through meticulous scrutiny, we determined that the amalgamation of these mechanical attributes at the 30% mixing ratio provides an optimal combination for attaining structural integrity, adaptability, and resilience in wall coverings. Significantly, this ratio also underscores a commitment to environmentally conscious material selection. Our study offers important new insights into the selection of wall covering materials by providing a detailed understanding of their mechanical behavior under various stress conditions. It aligns with the increasing significance of environmental responsibility in contemporary design and construction. By emphasizing the 30% mixing ratio, our findings establish a foundation for informed decision making, promoting the utilization of sustainable materials that achieve a balance between strength, flexibility, and longevity. This ensures optimal performance in practical applications while simultaneously minimizing the environmental impact.

“…Legal regulations impose a constant increase in the use of these raw materials, but it is incomparably lower than metals, glass, and paper. An easily available material is ground rubber waste in the form of rubber recyclate, which can be used as a filler in new composite materials [ 3 , 4 , 5 , 6 , 7 , 8 ].…”

Currently, there is a noticeable trend of modifying new materials by using additives from the recycling of harmful waste. This is to protect the environment by using waste to produce composites and at the same time to reduce the cost of their production. The article presents an analysis of the impact of the use of rubber recyclate obtained from the utilization of car tires as a sandwich layer of epoxy–glass composites and its impact on the strength parameters of the composite. The presented research is an extension of the previously conducted analyses on composite materials modified with the addition of rubber recyclate. The four variants of the materials produced contained the same percentage amount of rubber recyclate, but differed in the way it was distributed and the number of layers. Static tensile tests as well as impact strength and kinetics of damage to samples made with and without the addition of recyclate were carried out. Observation of the structures of the materials with the use of SEM was also performed. A significant influence of the method of distributing the recyclate in layers on the strength parameters of the materials was found. In the case of composites with three and two sandwich layers of recyclate, more favorable results were obtained compared to the blank sample. In addition, the values of the impact strength measurements were subjected to statistical analysis at the significance level of α = 95%. The distributions were tested for normality with the Shapiro–Wilk test, differences between pairs were tested with the Student’s t-test for dependent groups, and ANOVA differences were tested for independent groups. Using the Student’s t-test, it was confirmed that between the pairs of variables in the configurations reference sample and modified sample, there were significant statistical differences in the distribution of impact strength measurement results for all the analyzed materials. Statistical analysis showed a significant usefulness in the selection of the material with the best strength parameters and a significant role of statistical methods in the study of anisotropic materials.

“…The incorporation of low carbon mineral additives reduces environmental impacts, produces an environmentally friendly material, and minimizes energy consumption [5,6]. These additives may offer other options such as improving certain characteristics of concrete including strength, durability, rheological, and transfer properties [7][8][9][10][11]. In addition, the variation in the percentage of addition to the cement contributes to the improvement of the finished product.…”

Reusing expired cement (EC) in cement manufacturing is an alternative way for managing such industrial waste, so this process contributes to preserving the environment and reducing the need for raw materials which creates an innovative solution in circular economy strategies as well as producing a sustainable material. The purpose of this study is to investigate the possibility of using EC as mineral additives for the manufacture of new cement. The different formulations of cements are the results of CEMI subtraction up to 35% by weight with the EC. These modified cements have passed the same tests as a characterization of a CEMII. The obtained results show that EC changes the characteristics of cementitious materials (anhydrous, paste, and mortar). The new cement produced fulfilled the requirements in terms of chemical characteristics. In addition, the decrease in strength caused by EC incorporation is in accordance with standards. It can be stated that EC plays the role of a diluting agent in the new cement. Environmentally, it may be more efficient to use EC as an ecofriendly additive material.
