The basic mechanical characteristics of coarse aggregate concrete with seven different solid waste aggregate concrete concretes were determined and compared with NCAC to demonstrate the differences between the mechanical characteristics of solid waste coarse aggregate concrete and natural coarse aggregate concrete under equal pressure, as well as the trend in failure morphology, elastic modulus, and stress full curves of the various solid waste coarse aggregate concrete concretes under equal stress. With a maximum difference of 45%, the modulus of elasticity of the solid waste coarse aggregate concrete was smaller than the NCAC under equal conditions. Based on the Guo Zhenhai model, a porous micro-pumping effect of the self-combusted gangue and self-combusted gangue vitrified reinforced the concrete interface transition zone, and the polished surface of sheet waste, uncombusted gangue, and recycled concrete aggregate surface adhesion damaged the interface transition zone; finally, the uniaxial compressive stress strain curve for concrete with various solid waste coarse aggregates was developed for concrete with different solid waste coarse aggregate surface;.
In scientific science, the quest for effective waste source precursors for geopolymer production is ongoing. The ability of using calcined kaolin clay and fly ash as good precursors for geopolymers production is widely discussed and acknowledged. Calcined illite or kaolin clay in combination with salt cake from the aluminium scrap recycling industry after alkali activation delivers lightweight material from 540- kg/m3. Results show that waste clay type and salt cake content influence geopolymer properties, as materials with similar appearance behave differently. Metakaolin based geopolymers outperformed red clay based geopolymers, and they can withstand from 25 to 50 freeze cycles with strength loss from 10 to 65%. After 61 days of soaking time in comparison to metakaolin based geopolymers, the Sulfate attack displayed significant strength loss for red clay based geopolymers.
The relationship between MgO crucible and liquid slag was also shown, and it was found to play a vital role in metal recovery. The reduction rates of iron and copper are near to 100 percent, but their separation from slag during smelting is highly sensitive to temperature and basicity. Aluminum dross is an effective, green, and cost-effective substitute for copper slag, which means that these two industrial wastes can be converted into clean and value-added products, according to the study.
The thermoelectric generator converts waste energy into electrical energy using the Seebeck effect, which is one of the most common and widely used methods of producing electricity. Since the Seebeck effect converts temperature change into electrical energy, a TEG can be used anytime there is a temperature difference. In this review, TEG geometries and their associated problems are also discussed. In this paper, the latest TEG technologies and the challenges they solve are also addressed.
The main reason, according to three dimensions, intensity distribution, mean square displacement, radial distribution function, and time correlation functions, was that continuous formation of chemical adsorption with C-S-H is the primary reason. The ideal amount of microbe cement for solidifying and increasing MSWI fly ash is 30 percent above range, according to the results of compressive strength, microstructure testing, and heavy metals' leaching concentration.
