“…For materials with the low variability of material parameters in assortment grades (such as steel or concrete), reflectance measurement methods are widely used because of their simplicity, efficiency and easy interpretation [24]. In the case of masonry ceramic elements, such methods are more often used to assess the homogeneity of materials than to determine their mechanical properties [25]. The method successfully used to locate excessive humidity is thermovision.…”

Construction and demolition (C&D) waste management should be accordance with the waste management hierarchy. In practice, C&D waste are often downcycling. It is the result of many factors, including lack of awareness about the value inherent in waste. The paper presents analysis of the adaptability of non-destructive testing (NDT) methods for technical assessment of waste properties. As part of the work, non-destructive testing methods were described and classified in accordance with material and the features they enable testing. The publication presents examples of the use of NDT in the recovery of building materials during construction projects, in the field of influence of technical information of waste on the way it is managed. Finally, a scheme of waste management process during the renovation of an object with the application of NDT methods was presented.

“…Another problem is that of implementing an adequate maintenance plan in complex units such as facades and their cladding (Ferreira et al 2021). This is the reason for which a number of Portuguese researchers have proposed a methodology with multiple criteria to prioritise the actions to be taken (Madureira et al 2017), given that, among other reasons, it is quite different if parts of the envelope are finished with ceramic cladding (Souza et al 2018), with continuous mortar finishing (Galvão et al 2018), or others. In order to facilitate these decisions, as well as to sequence building inspection processes, it would be quite useful to use specialised software (Silva and de Brito 2019).…”

The object of this research is to identify the list of climatological variables involved in the appearance of construction failures in the external walls of dwellings, through the analysis of over one thousand cases. The data source used consisted of the judicial records of the Justice Administration, a source to which few researchers have access, given the dispersion of the data and the permissions required to access it. Once obtained, all situations pertaining to dwellings were read and annotated, until 100% of the cases were accounted for, and percentages of recurrence were calculated for each of the 9 different types of failures that were described. A study was carried out by 'strips of climatic location' according to four climatological variables (situation, latitude, climate and annual rainfall) that were sorted from largest to smallest to obtain the 'ranks of pathology concentration' according to the resulting preponderance. With these results, technicians will be able to know the most problematic climate-geographical areas, through the determination of the ranks of normalised frequencies, allowing them to take the necessary measures during the construction process. The lessons learnt can be incorporated in maintenance plans to optimise preventive maintenance frequency and actions.

“…In this study several experimental programs were carried out for 4 years, and 98 rendered façades were tested on 42 buildings (Tables 1 and 2), based on observation and measurement parameters The building façades were chosen randomly and had various render solutions (conventional renders with paint; coloured pre-dosed mortars) and substrates (concrete blocks, hollow brick leaves with or without an air cavity, stone masonry walls). The discussion of the results is not within the scope of this paper as some of them have been already published and discussed into detail for several techniques [19,23,35,36].…”
