Study on Microstructure of Recycled Aggregate Concrete by Scanning Electron Microscopy: A Review
No full textRecycled Aggregate Concrete (RAC) is a new type of concrete made by utilizing waste concrete as aggregate after treatment. With the enhancement of environmental awareness and resource conservation, but the microstructural part of recycled aggregate concrete is not as important as the macro performance enhancement aspect by scholars. And Scanning Electron Microscope (SEM) is a powerful tool for microanalysis, which can provide high-resolution images of samples as well as information on surface morphology and microstructure. In this paper, the micro-structure of RAC will be comprehensively analyzed according to the performance characteristics of RAC materials and the relevant analysis technology of SEM. Based on the microscopic technology of SEM, the research progress of the micro-structure of RAC was carried out, and the morphology and distribution characteristics of recycled aggregate particles, pore structure and porosity, the interface combination between recycled aggregate and cement matrix, and the relationship between micro-structure and RAC properties were summarized, which provided theoretical support for the future understanding of the micro-structure of RAC, increased the understanding of the micro-structure of RAC materials, and more systematically understood the application of microscopic analysis methods in RAC
Development and Quality Evaluation of Cookies from Lima Bean and Emmer Wheat
No full textThe increasing interest in nutritious and functional foods has led to the investigation of alternative grains with enhanced health benefits. This research centres on developing highly nutritious cookies using lima bean (Phaseolus lunatus) and emmer wheat (Triticum dicoccon Schrank). These grains are cultivated for their outstanding nutritional qualities, such as high protein, essential minerals and bioactive compounds, making them ideal for creating health-promoting food products. The physical properties and chemical composition of lima bean and emmer wheat seeds were investigated. Five distinct trials with varying blends of lima bean and emmer wheat were carried out, with proportions of emmer wheat to lima bean being 50:50 (T1), 60:40 (T2), 70:30 (T3), 80:20 (T4) and 90:10 (T5). The physical and sensory analysis of the all developed cookies was performed and sample T3 was selected for physical and chemical analysis among all the samples after sensory analysis. Analytical methods were used to evaluate the nutrient composition, including protein, fiber and mineral content. Storage study of 60 days developed cookies also evaluated. It was found that the cookies gained moisture and lost fat, protein, fibre and energy over the storage period, with carbohydrate content showing minor fluctuations. The data obtained in the present investigation are sufficient to conclude that lima bean is an effective substitute for wheat flour in cookies preparation. The cookies prepared using lima bean were found to be acceptable in terms of quality characteristics. This substitution increased the protein content of the cookies. The cookies made with a 30% replacement of wheat flour with lima bean flour were the most acceptable
