Título: AVALIAÇÃO DA DEMANDA HÍDRICA POR EMPREENDIMENTOS DE LAVAGEM DE VEÍCULOS NA CIDADE DE RIO VERDE - GO Autor(es): Vale, Alex Moreira do Primeiro Orientador: Silva Júnior, Édio Damásio da Abstract: This study aimed to evaluate the water demand associated with vehicle washing businesses in the municipality of Rio Verde (GO), Brazil, with emphasis on the exploitation of groundwater resources. The methodology integrated water use permit data obtained from the Water Resources Information System of the State of Goiás (SIRHGO) with information collected through on-site visits to establishments. Data regarding water consumption, types of washing systems, service profiles, and management practices were gathered and subsequently processed and spatially analyzed using QGIS software. The results showed a predominance of semi-automatic washing systems, as well as a strong dependence on groundwater abstraction. The total estimated water demand was 156,894.40 m³/month, a value significantly higher than the granted abstraction volume of 102,670.42 m³/month, indicating a possible discrepancy between actual consumption and established regulatory limits. Thus, vehicle washing activities represent relevant water use in the local context, with potential pressure on groundwater resources. The findings highlight the need for the adoption of more efficient technologies, as well as improvements in public policies and management instruments that promote the sustainable use of water resources.

Título: DESENVOLVIMENTO DE CONCRETO DE ULTRA ALTO DESEMPENHO COM INCORPORAÇÃO DE REJEITOS DE MINERAÇÃO E FIBRAS METÁLICAS Autor(es): Morais, Guilherme César Martins de Primeiro Orientador: Sales, Marcel Willian Reis Primeiro Membro da Banca: Castro, Alessandra Lorenzetti de Segundo Membro da Banca: Silva, Philippe Barbosa Abstract: This study investigates the development and properties of Ultra-High Performance Concrete (UHPC) with sand incorporation from mining tailings, seeking to combine high structural performance with sustainability in civil construction. The first chapter presents a systematic literature review that analyzes the state of the art of UHPC, highlighting the fundamental role of mineral additions and metallic fibers in optimizing the compactness of the matrix and ductility of the material. The second chapter details the experimental methodology and the materials used, focusing on the substitution of conventional fine aggregates with mining tailings, aiming to mitigate the environmental impacts of natural sand extraction and reduce production costs. The literature review suggests that the use of mining tailings is technically feasible, and there is a gap to be explored. The results indicate that the mechanical properties remain superior, with a compressive strength above 120 MPa, a dense matrix, and a refined ITZ as shown by SEM. When metallic fibers are incorporated, they combine high fracture energy, toughness, and tensile strength, which are fundamental for applications in critical infrastructure.

Título: ARGAMASSAS DE REVESTIMENTO À BASE DE BIOCHAR DO BAMBU E AREIA ARTIFICIAL Autor(es): Tamasauskas, Whellysonn Viana Primeiro Orientador: Alves, Michell Macedo Primeiro Membro da Banca: Sales, Marcel Willian Reis Segundo Membro da Banca: Bacarji, Edgar Abstract: The growing concern with sustainability in the construction industry has driven to research aimed at replacing conventional materials by alternatives that have a lower environmental impact. In this context, the present study evaluated the performance of rendering mortars with partial replacement of Portland cement by bamboo biochar and river sand by manufactured sand derived from crushed stone dust. Five experimental mixes were produced, with gradual substitutions of cement by biochar and natural sand by manufactured sand at levels of 0%, 3%, 5%, 7%, and 10%. The tests performed included compressive strength, bond strength, and capillary water absorption. A systematic literature review revealed that incorporating biochar between 1% and 5% can improve the mechanical strength of mortars. Microstructural analyses indicated an increase in hydration products formation, contributing to the improvement in mechanical performance. Experimental results confirmed that replacing up to 5% of the cement by biochar leads to significant gains in compressive strength and adhesion, while maintaining satisfactory performance in terms of capillary absorption. On the other hand, mixes with substitutions above 7% showed a reduction in mechanical performance. Regarding the fine aggregate, manufactured sand demonstrated technical performance compatible with that of natural sand, proving to be a viable and sustainable alternative. It is concluded that combining biochar and manufactured sand, in appropriate proportions, can contribute to the development of more sustainable construction materials without compromising essential properties such as mechanical strength and durability.

Título: DELIMITAÇÃO DE UNIDADES DE PAISAGEM APLICADA A BACIAS HIDROGRÁFICAS, UTILIZANDO PARÂMETROS GEOMORFOMÉTRICOS E EDÁFICOS Autor(es): Queiroz, Alinne de Assis Veras Primeiro Orientador: Angelini, Lucas Peres Primeiro Membro da Banca: Angelini, Lucas Peres Segundo Membro da Banca: Moura, Derick Martins Broges de Terceiro Membro da Banca: Silva Júnior, Édio Damásio Abstract: There are many methods for environmental assessment contributing to maintain ecosystem services, enabling more sustainable use of natural resources and reducing environmental problems. Landscape Unit (LU) Assessment Method stands out among different ones, which is a product of the official Environmental and Productive Zoning (ZAP, Brazilian acronym) manual from Minas Gerais State, a tool designed to develop and monitor economic, social, and environmental management plans. However, the subjectivity in delimitating these units emerges as a challenge, potentially compromising the results accuracy and the environmental analyses effectiveness. Therefore, this paper focuses on delimitating the Landscape Units by geomorphological parameters basing on terrain shape variables (horizontal and vertical curvature), slope, and edaphic characteristics to assist in soil vulnerability and suitability analyses in the VerdinhoRiver watershed. These data were analyzed and considered to generate a detailed classification of Landscape Units, enabling to identify zones with geomorphological and soil characteristics; finally allowing analyzing the units according to their uniqueness in relatively homogeneous natural aspects. The results indicate that the proposed methodology helped to reduce subjectivity in unit definition, making the process more replicable and coherent. Furthermore, the delimited units show a direct relationship with different levels of soil vulnerability and suitability, contributing to more efficient territorial planning. It is concluded that the adopted approach may support future studies, contributing to identify priority areas for conservation and sustainable use. The integration of geospatial technologies proved to be an effective tool for delimiting the Landscape Units, providing greater accuracy in environmental analysis and decision-making support.
