Opis:
Activated carbon is a solid carbon compound that is composed of carbon in the form of charcoal. It plays a major role in some industrial applications such as water and air purification because of the strong adsorption of its surfaces and its tendency to remove some volatile organic compounds (VOC) and most of contaminants from the water, air or some other material. Various base materials are used in the manufacturing of activated carbon, including different woods and certain synthetic materials. According to the scope of new research, it is possible to produce activated carbon economically using coconut shell waste products. In our work, the coconut shells were burnt using a muffle furnace and at a range of temperatures in 300 ºC - 390 ºC. The elemental compositions of manufactured activated carbon were analyzed using X-ray fluorescence (XRF) spectrophotometer, while the surfaces of manufactured activated carbon were microscopically analyzed using an optical microscope. Thus, the range of 330 ºC - 350 ºC was considered as the most adequate temperatures for the manufacturing process of activated carbon from these coconut shells. Beyond the non-metal carbon, 68.85% Fe and 31.15% K are generated.

Opis:
Due to the environmental and economic crisis, this study focus on generating product using agricultural waste as well develop an alternative construction material that will lessen the social and environmental issues. It also paved the way to the recognition of using coconut shells and fiber as a substitute for aggregates in developing concrete hollow blocks. As a whole, the study' main concern is the environment and the construction and building technology to enhance natural world as well as building materials. This also aims to design a technical specification of concrete hollow block using coconut shell and fiber as aggregates that will meet the ASTM requirements in order to help contribute to the industry in saving the environment, to encourage the government to find solutions regarding the disposal to landfills of waste materials and save the environment, to provide new knowledge to the contractors and developers on how to improve the construction industry methods and services by using recycled coconut shells and fibers, and to sustain good product performance and meet recycling goals. A conventional concrete hollow block was compared to concrete hollow blocks with coconut shells and fibers of the same proportions. Observations from the tests performed were conducted in the laboratory where precise data were gathered and completely attained. Some of the interesting insights of the study are: (a) coconut shells and fibers are applicable as a partial substitute as coarse aggregates for concrete hollow blocks. (b) the good indicators of coconut shell and fiber quality as aggregate of concrete hollow blocks are particles, shape, and texture, resistance to crushing, absorption and surface moisture, grading, resistance to freezing and heating and light-weight.; (c) coconut shells and fibers are classified as miscellaneous material used for wall panels and partitions and (d) a non-load bearing type of hollow block because the compressive strength gained higher than the conventional concrete hollow blocks after 28th days
