“…The methods used to evaluate sand's durability were same to those used to evaluate gravel's toughness. This project's coarse aggregate was comprised of crushed gravel with a nominal maximum size of 20 mm [29][30][31][32]. After being submerged in water for 24 hours, the coarse aggregate utilized in this study had their water absorption tested under SSD (saturated surface dry) conditions by having the excess surface water wiped off with a wet cloth.…”

The importance of using recycled materials like rubber in construction materials is rising rapidly today. By incorporating used rubber into cement and mortar, we can save landfill space and reduce our dependence on natural resources. Rubber scrap can be mixed in as either fine or coarse aggregate. Add it to Portland cement for a stronger, more durable product (PC). This paper reviews the studies conducted so far on the feasibility of using waste rubber in place of conventional PC-based mortar and concrete’s natural fine aggregate. The strength and water-absorption capacity of materials made from ash from scrap rubber tyres were measured. Test results indicate that waste rubber ash was substitute with natural sand up 10% then strengths of the sample were enhanced after increasing the content of waste rubber tyre ash then strength was decreased. Water absorption capacity of samples was improved as increased the content of waste rubber tyre ash into concrete mix.

“…The solution also contains potassium chloride as an inhibitor, calcium carbonate as a weightingbridging agent and potassium hydroxide as a pHincreasing agent. The concentration of structure formers, inhibitors, weighting agents and leaf powder was selected based on literature review on similar additives (16,(31)(32)(33). Recipes of the studied solutions are presented in Table 1.…”

Drilling muds play the essential role the drilling process as they perform many functions, such as the removing of drill cuttings and controlling well pressure. Water-based drilling muds, through the use of more environmentally friendly additives, can meet increased environmental requirements. Many researchers have studied the effects of different natural materials on drilling mud to find environmentally friendly and effective drilling mud materials. The popularity of using waste materials is mainly due to their cost and favourable environmental impact. Performed literature review showed that the rheological and filtration characteristics of water-based drilling muds are enhanced with the addition of leaves of various plants and trees. This article presents investigations of clay-free drilling mud with the addition of birch and aspen leaf powder. This is relevant in the autumn period, since fallen leaves are solid municipal waste and should be disposed of by removal to landfills. The obtained data indicate the possibility of using leaf powder in the drilling mud composition. Addition of leaf powder to the base mud increases the gel strength and plastic viscosity of the mud. In an extent reduces the yield point and filtration index. Rheological parameters increase by 10-30% and filtration index decreases up to 15-17%.

“…Additionally, Portland cement-based concretes have durability issues, leading to 40-50% of construction budgets being spent on repairs. This underscores the need for alternative cement materials that are more sustainable and address OPC's shortcomings (3). Such environmental awareness has heightened interest in converting industrial by-products into concrete ingredients.…”

This study employs fine glass powder as a partial replacement for ordinary Portland cement in order to better understand the complex effects of high temperature on the microstructure and compressive strength of cement mortar. The study aims to identify the optimal mix that maximizes the benefits of glass powder incorporation by experimenting with different glass powder sizes (38 µm, 53 µm, and 75 µm) and replacement rates (10%, 20%, and 30%). At 25 o C, 200 o C, 400 o C, 600 o C, and 800 o C, mortars containing glass powder were subjected to compressive strength tests. Mortar samples were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Thermo Gravimetric analysis (TGA) to gain insight into their behavior at high temperatures. Mortar mixes containing 10% glass powder (38 µm size) performed best at temperatures below 400 o C, with an average residual strength index value of 90.7% compared to 87.8% in the reference sample. The glass powder mortars with 10% and 20% replacement rates functioned better at higher temperatures of 800 o C, losing just 52-57% of their strength as opposed to 72% in the control sample. The increased pozzolanic activity attributable to the addition of glass powder is shown by XRD and SEM analyses to account for the increased strength of mortar by consuming more portlandite (Ca(OH)2). TGA study has shown that at temperatures exceeding 400 o C, to bermorite and other hydrated products become dehydrated, which may account for the strength reduction.
