    Comparativo da Produção de Concreto na Amazônia – Cidade de Santarém
    (INSTITUTO DE TECNOLOGIA, 2014) SANTOS, Ivens Silva dos; POMPEU NETO, Bernardo Borges; OLIVEIRA, Dênio Ramam Carvalho de; MACÊDO, Alcebíades Negrão; MAGALHÃES, Edilson Marques
    The study compared the production of concrete in batching plants and on-site in Santarém-PA, identifying the most used methods and the factors affecting material quality. Technical visits and interviews with professionals highlighted the prevalence of mixer use, lack of technological control, and poor aggregate quality as main challenges.

    Concretos com Agregado Graúdo a Partir dos Resíduos de Cerâmica Vermelha
    (Universidade Federal do Pará, 2015) SANTOS, José Augusto Vieira dos; OLIVEIRA, Dênio Ramam Carvalho de
    This study investigates the technical feasibility of using waste generated in the production of red ceramic artifacts (bricks and tiles) as coarse aggregate in Portland cement concrete. The research proposes the partial or total replacement of natural coarse aggregate with red ceramic waste (RCV), aiming to reduce environmental impact and provide a more noble destination for these residues. Material characterization tests, analysis of concrete properties in both fresh and hardened states, and compressive strength evaluation were conducted. The results indicate that replacing up to 20% of natural coarse aggregate with RCV maintains concrete strength close to conventional concrete, while higher replacements result in significant reductions in strength.
