Influência da Substituição do Agregado Miúdo Natural por Resíduo Cerâmico na Produção de Argamassas.

In order to mitigate environmental impacts generated by both the ceramic industry and civil construction, this paper aims to analyze the technical feasibility of using ceramic material waste as an alternative material for the production of lining mortars. Thus, the methodology of this work was developed from the production of coating mortars with replacement of the natural fine aggregate by red ceramic waste in the proportions of 0%, 20%, 50% and 100% of fine aggregate, evaluating the performance in the fresh and hardened state of the mortars. In the fresh state, the substitutions reduced the spread and the mass density of the mortars. In the hardened state, the substitutions of 50% and 100% positively influenced both the compressive strength and flexural tensile strength, increasing significantly compared to the reference mortars.
