“…O experimento foi realizado mediante ensaios de resistência de aderência à tração direta efetuados em pastas de gesso aplicadas sobre bases de blocos cerâmicos e de concreto, estruturais e de vedação (FREITAS et al, 2014;MELO et al, 2020). Para uma melhor visualização, são apresentadas na Figura 3 as variáveis dependentes e independentes utilizadas.…”

Resumo O uso de pastas de gesso como revestimento de paredes internas é uma das técnicas mais comumente empregadas em obras no Brasil, geralmente efetuado em pequenas espessuras por meio de aplicação manual ou, ainda em menor espessura, por projeção mecânica. O presente trabalho objetivou avaliar experimentalmente a resistência de aderência de revestimentos executados em pasta de gesso com aplicação manual em diferentes substratos e alturas de aplicação. Como variáveis foram testados quatro tipos de blocos (blocos cerâmicos e de concreto, com função de vedação e estruturais), duas profundidades de ensaio da pasta (superficial e com cortes até o substrato) e três alturas de aplicação (até 0,6 m; entre 0,6 m e 1,2 m; e acima de 1,2 m). Os resultados apontaram a forte influência da base e da profundidade de corte na aderência, o que não foi encontrado na altura de aplicação do revestimento (ergonomia), em decorrência do natural processo de aplicação da pasta de gesso efetuado com pressão da massa sobre a parede.

“…In cementitious substrate-matrix contact, there are also several studies, such as the works developed by [ 10 , 11 , 12 , 13 , 14 , 15 ], which aimed to understand and improve the adhesive’s ability to extend over the substrate. However, should be noted that there is still a need for studies aimed at improving the current model for assessing adhesion strength.…”

“…Recently, a work in the area of mortar coatings, carried out by [ 15 ], evaluated the bond strength from the crack propagation test in stress mixed mode (MMF test), which simulates tensile and shear forces, simultaneously. The authors concluded that the results of tensile bond strength were higher than the results obtained by the MMF test, indicating an overestimation.…”

Despite technological advances in the production processes of the materials for ceramic façade coatings, the problems of detachments are still frequent. Therefore, this work aims to investigate, through a literature review, the existing gaps related to the adhesion ability of adhesive mortars, identifying new research needs that can better explain the behavior of the material. In addition, an experimental procedure was developed to evaluate the mechanical capacity of adhesive mortars when subjected to cyclic stresses. Dynamic stress measurements are presented for several blocks of mortar and on similar blocks but with a slot drilled prior to measurements (intended to represent failure). From these data we calculated values of stress energy, elastic energy, and dissipated energy. The experimental results showed that the energy involved in the test process accompanied the load values and current stress values. The mortar samples with the previous failure absorbed and dissipated less energy than mortars without failure, showing that materials that have less energy to dissipate, are materials that have developed less capacity to adhere, that is, to keep their parts together.

“…The current use of ceramics inside buildings, next to the construction of brick walls, is the floor finishing layer. This, however, has to provide the right properties to prevent slips, trips, or falls which can cause injuries to the human body and to present the best performance of building [19]. Between 2019 and 2020 alone, there were about 200,970 reported cases of a non-fatal injury caused by slips, trips, or falls (Labour Force Survey, Newport, UK) that could have been prevented by the appropriate choice of surfaces with the correct slip resistance.…”

The safety of the use of construction facilities should be a priority in today’s busy world, where it is not difficult to get involved in an accident. Most of them, due to the pace at which we live today, are caused by slips, trips, and falls. This work presents a detailed analysis of the resistance of ceramic floors to these events, taking into account the surface properties and conditions (dry/wet), which, as presented, have a significant impact on the final slip resistance values. This study also investigates the relationship between surface roughness and anti-slip properties. According to the obtained results, it can be concluded that the surface roughness is not the main determinant of slip resistance, and the final value of it is influenced by many components that should be considered together and not be neglected when designing the surface finish. Furthermore, based on experimental measurements, it can be noted that the highest slip resistance in both wet and dry conditions showed the unglazed tiles with lapatto finish and the glazed tiles without any extra finish.
