    Aprovechamiento de una ceniza de fondo de caldera en la fabricación de un concreto liviano
    (Universidad de San Buenaventura - Cali, 2015) González Muñoz, Alexandra; Amu Bolaños, Maribel
    The present study was conducted in order to establish, from the research, physical and mechanical behavior of a traditional concrete when it is added in different proportions a light ash bottom of the boiler (BA) by-product of burning cane sugar during papermaking. This product replacement part to the large and fine aggregate in the hydraulic concrete that, in the case of this research, corresponds to a naturally occurring gravel product crushing quarry rock and river sand cauca.

    Caracterización mecánica y eléctrica de la aleación de aluminio 6201 de uso en la fabricación de cables eléctricos
    (Universidad de San Buenaventura - Cali, 2015) Bonilla Lemus, Diego Fernando; Amu Bolaños, Maribel
    This degree work was performed with the purpose of establishing their effect aging heat treatments on the mechanical properties and electrical conductivity aluminum alloy 6xxx series. For 3 different heat treatment states of tension tests where strengths above 200 MPa, microhardness tests in which greater than 70 Hv, tests and differential scanning calorimetry were obtained resistivity traction hardnesses were achieved they were performed. As a further result of the stress tests, the type of fractures through scanning microscope to determine the ductile or brittle behavior after the failure was examined.
