Abstract: A construção civil é a responsável pelo grande consumo de matérias-primas e principalmente por agregados, dessa forma, proporcionando possíveis impactos ambientais. Com isso, diversas pesquisas são realizadas visando o emprego de materiais tidos como inservíveis no mercado construção civil, contribuindo com a preservação de recursos naturais não-renováveis e amenizando o acúmulo de resíduos descartados de forma inadequada. Esse artigo tem como objetivo buscar na literatura formas de substituição de agregados utilizados na construção civil. Foi realizada uma revisão da literatura, em que se buscou artigos publicados de 2015 a 2019, que se tratasse de estudos experimentais.....

Abstract:In this paper, The stability of a class of infinite-dimensional nonlinear interconnected vehicle following systems was studied. Under the assumption that the systems are globally Lipschitz, from the
conditions of stability of isolated subsystems decomposed from the interconnected nonlinear systems, by applying vector Lyapunov function method and comparison principle, the sufficient conditions of exponential
string stability for this class of interconnected systems was obtained. The obtained sufficient criterion is delayindependent, thus it is easy to test in practice..

Key Word:nonlinear interconnected systems, string stability, global asymptotic stability, vector Lyapunov function, time delays
