In this dissertation, we study Cohen-Macaulay and Gorenstein properties of the fiber cone of an ideal I of d-dimensional Cohen-Macaulay local ring (R,m).We also obtain a formula to express the multiplicity of the fiber cone of a m-primary ideal I in terms of mixed multiplicity ed−1(m|I) and superficial elements. As a consequence, we have that the Cohen-Macaulay properties of the fiber cone of I, with minimal mixed multiplicity and almost minimal, is characterized by the reduction number of I.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESNeste trabalho estudamos a Cohen-Macaulicidade e a Gorensteincidade da fibra especial de um ideal em um anel local (R,m) de Cohen-Macaulay com dimensão d.
