Concrete is widely used in turnkey projects and small-scale projects. An alternative sustainable coarse aggregate for natural coarse aggregate can reduce the amount of pollution and preserve natural resource. An attempt is made in this research project to use locally available soil from the site and fly ash waste to prepare an alternative sustainable coarse aggregate for concrete to be used in small constructions. Concrete mix is prepared with natural aggregate and expanded fly ash clay aggregate EFCA and their fresh state, strength and durability properties were studied. The slump value of EFCA concrete under same water content is similar to that of natural aggregate concrete. A compressive strength of 21.45 MPa is achieved for EFCA concrete, which is acceptable for normal structural concrete. Flexural strength of 3.67 MPa is measured. Rapid chloride penetration test conducted on EFCA concrete showed moderate...

Information security is the art, science, and technique of securing the computer's systems, the data and information stored in computer systems, computer networks, and also the information security management. Information security is critical while designing an information system or an information service. Data related to information security research are downloaded from the Web of Science and analyzed for literature growth, top productive country, institution, and author, top funding agency, top contributing source title, and the area of research. This chapter reveals USA is the top contributing country while China is also making rapid strides in this field. Chinese funding agencies fund most of the research. However, English is the preferred language of communication.

Concrete specimens with conventional natural aggregate and EFCA as coarse aggregates were prepared separately and exposed to elevated temperatures of range 200°C, 400°C, 600°C and 800°C, observed for surface changes like change in color and formation of visual cracks, tested for loss in mass, strength and water absorption, analyzed by XRD for mineralogical changes through variation in chemical composition. Specimens when exposed up to 400°C has not shown any notable changes in the above property, beyond which strength of both specimens started to decrease gradually, at higher temperature EFCA mix showed loss in mass of 4.5% compared with normal concrete, visual observation of specimen surface showed EFCA specimens sustained cracks till 600°C. EFCA mix also showed a constant rate of water absorption. Concrete with EFCA showed consistently higher compressive strength at higher...

Natural aggregate used for ordinary concrete is obtained by quarrying, which cause serious environmental issues. An alternate course aggregate is needed for sustainable development. The objective of this research is to produce an alternative course aggregate in combination with soil available locally near site along with fly ash, to test its properties to make it fit for concrete. Method: An alternative coarse aggregate is produced from red soil and fly ash mixed at various ratios, 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, fresh aggregate granules of different sizes less than 10mm is prepared using hand press, the aggregates were sundried in shade for 24hours, oven dried at 110°C, burned in Muffle furnace at temperature of 950°C and cooled gradually to reach room temperature. After the production, the specific gravity, bulk density, water absorption, Impact and aggregate crushing of the aggregates wer...
