The construction industry stands out on the world for its great socioeconomic influence. As a result, to the high consumption of feedstock and unrestrained generation of construction waste (RCC) through a huge production chain that causes negative impacts on the environment, causing many problems. In this context, techniques that seek to insert leavings into the production chain, such as the manufacturing of mortar with reduced environmental impact, should be valued. In this sense, the red ceramic waste (RCV) stands out, which is abundant waste, widely characterized and that has several possibilities of application, and several sources, among them the deposits, where the residues present greater nobility and homogeneity. In this context, the present research seeks to investigate the losses occurred in the ceramic deposits, possible causes and the viability of the production of mortars with the addition of 1%, 2%, 5%, 8% and 10% of red ceramic tile residue, as final destination of the residue obtained from five deposits in the municipality of Barra do Garças - MT. Through of interviews to the owners of the five deposits examined, we sought to analyze the percentage losses, as well as other factors of the generation and destination of the RCV. In the interviews, was possible to observe that the red ceramics of the investigated deposits vary from 5% to 10%, in addition, it can be seen that 80% of the deposits are destined for waste in the municipal dump and 40% of the companies are interested in recycling practices. In order to contribute to the study of recycled mortars as a proposal for the disposal of RCVs, residues of red ceramic tile were collected for benefit and application in the manufacture of mortars, without trace 1: 2: 9 in different proportions of RCV for later testing and evaluation with the common mortar. After the mortar curing process, they were tested to avoid flexural resistance, axial compression and water absorption by capillarity. No flexural strength tests, such as rates above 1% RCV, obtain equivalent strengths and even higher than the reference rate, highlighting that the addition of 10% RCV results in a flexion strength 23% higher than ordinary mortar . Regarding the compression behavior, since the recycled mortars reach at least 82% of the axial compression resistance of the reference mortar. The absorption of water by capillarity, aggregated with the addition of RCV in proportions up to 8%, resulted in lower absorption rates compared to ordinary mortar. In short, a recycled algorithm presents the following results regarding the analyzed properties, mainly as the additions of 5% and 8% of RCV. So, through the data obtained, is able to conclude which there is a large availability of waste with little contamination in the deposits, there is interest in partnerships for recycling part of the waste and, considering the tests carried out, it is possible to obtain recycled leavings with rhe same characteristics to common mortar, characterizing a relevant progress in which it refers to a practice of sustainability in civil construction.
