“…Other it was methods or materials, like recycled aggregate (RCAs), high-performance concrete experiments, and less porous geocrete in structures, have been widely demonstrated to be essential in framework durability (Zhanggen et al,2018;Vivek et al, 2021;Mugahed et al,2021). Building Information Modeling (BIM), on the other hand, is used to test concrete or wall plate performance to ensure durability or building life cycle (Wu & Lepech 2020;Krentowski al., 2021).…”

Even though experts had been monitoring infrastructure quality previous to the COVID-19 epidemic, they had not normally widely highlighted the importance of constructing high-quality infrastructure. The lifespan of a structure is a significant consideration in evaluating how long it will last. This, however, necessitates a reevaluation of infrastructure durability to promote more sustainable growth. Based on these facts, this paper presents a method for measuring building durability utilizing structure deformation effects. The findings indicate that building durability will be acceptable in cities if building deformations in the serviceability state (SLS) do not exceed those of the ultimate limit state (ULS).

“…Life cycle prediction is becoming more popular these days (Wu & Lepech 2020;Krentowski al., 2021). A concrete life cycle is defined as "the anticipated duration during which a whole component of the structure will be used for its original purpose, thus monitoring the building with minor maintenance."…”

“…In the studied type of buildings, a typical prefabricated system was used for external curtain walls. It consisted of a concrete structural layer, thermal insulation from expanded polystyrene or mineral wool, and an external layer of textured concrete [ 8 , 10 ]. The durability of the external partition formed in this way is determined by the effectiveness of the implementation of the connection of the concrete layers.…”

Degradation Analyses of Systemic Large-Panel Buildings Using Comparative Testing during Demolition

2022

Assessment of the technical condition of large-panel buildings, due to their on-going use and covering resulting from thermomodernization works, is problematic. Results from non-destructive tests (NDT) are subjected to high uncertainty. Destructive tests, which give results with the highest level of confidence, are practically not used. Local sampling for testing gives only a partial image of the condition of a prefabricated building. In this type of construction, joints connecting the precast elements are the most vulnerable to degradation. Access to them is technically difficult. Demolition of this type of building is extremely rare. However, it is a unique opportunity to perform a full spectrum of both NDT and destructive testing. This gives an opportunity for large-scale demolition sampling to identify hidden defects and compare the results obtained by different methods. The comparison of results allows for the scaling of NDT methods and reveals the presence of typical relationships. The paper presents visual, non-destructive, and destructive tests’ results of an over 40-year-old large-panel building scheduled for demolition. The design of this building is repetitive and similar to solutions found in thousands of other buildings. The usefulness of particular research methods for evaluating the technical condition of prefabricated buildings has been determined.

“…Many publications focus on sustainability, which is a very wide concept that has been considered from many angles -including the use of wooden structures in construction [1][2][3][4] and various other topics [5,6] The hydrothermal behaviour of facades and new methods for repairing biocorroded facades [7,8] are being investigated by a number of world-renowned authors [9]. Some articles [10] focus on examining and assessing the status of external walls, in particular, the joints between the layers and their real physical and mechanical parameters. These articles often formulate recommendations on effective testing of the joints that are difficult to reach and suggest strengthening of the joints that are at risk.…”

Application of additional insulation to ETICS on surfaces with biocorrosion

et al. 2021

View full text Add to dashboard Cite

The paper presents partial outputs from an experiment that demonstrated the impact of applying an additional insulation on an existing contact insulation system with a green-algae surface. The aim was mainly to detect the development of microorganisms in the gap between the original and the new insulation. The existing ETICS on the polystyrene-based contact thermal insulation system and EPS-based additional thermal insulation were used in the experiment. A theoretical modelling of temperature conditions showed that this type of doubling the insulation presented the highest risk of condensation of water in the gap between the insulation layers and that these conditions presented suitable humidity conditions for the growth of microorganisms. The reason for the experiment is to demonstrate the need to eliminate microorganisms before applying an additional thermal insulation to surfaces with biocorrosion. This is especially the case where EPS is used. The temperature and humidity parameters obtained during the experiment can be used to model the moisture regime in the gap of other types of insulations (e.g. MW, PUR, PIR.)
