    Abstract: This paper describes the fabrication and characterization of a piezoelectric ceramic fiber/aluminum alloy composite using the Interphase Forming/Bonding (IF/B) method. A metal-core piezoelectric ceramic fiber is very fragile and reacts with molten aluminum; therefore, general fabrication processes such as diffusion bonding and casting are difficult... Show More

    Abstract: An evaluation of the Itakpe iron ore tailings (IOT) for concrete production has been carried out using the material to replace sand and cement, in proportions of 5 % up to 30 %, and curing for periods 90 days in water. Characterization of the material showed that it has pozzolanic properties, and can be used as a retarder for hot-weather concreting... Show More
