Special Issue Information

Dear Colleagues,

Rapid economic development, which is also noticeable in the construction industry, generates many new scientific problems that must be addressed, e.g., in order to meet the requirements of the modern economy. The avenues of scientific research are not only aimed at the continuous improvement of the technology used to erect new facilities, increasing the level of occupational safety, and reducing construction time and costs, but also at increasing the durability of existing structures from different stylistic periods.

These goals can be achieved by various mean, including the use of modern technologies in construction projects, the automation and robotization of construction processes, the use of modern information technologies, and the development of modern methods of planning, organizing, and managing construction processes. This Special Issue aims to present the latest developments in this area.

We welcome original manuscripts concerning, but not limited to, the following:

  • Modern solutions concerning devices that are used in the construction industry, including the automation and robotization of construction processes, with particular emphasis on the risks and hazards associated with them;
  • Modern technological and organizational solutions in the construction industry, including research methods and ways of securing structures and building objects from different stylistic periods;
  • The latest information technologies addressing the various problems that occur in the investment process;
  • Interdisciplinary research related to occupational safety, including accident modeling, occupational risk assessment, risk management, and occupational safety, as well as the impact of automation and robotization on occupational safety;
  • Applications of virtual reality (VR) technology for research and training purposes;
  • Methods used in forecasting processes, events, and phenomena that may occur in the future in the construction industry.

The objective of this work is to develop a new composite material by substituting sand with recycled waste glass (RWG). Different volume percentages of RWG varying from 0 to 50% were incorporated into concrete, with maximum size that did not exceed 1.25 mm. The microscopic characterization by scanning electron microscopy SEM-EDS and optical microscopic test, as well as the durability against alkali silica reaction (ASR) test, were performed respectively to visualize the morphology and assess the damage caused by ASR. Furthermore, the mechanical and thermophysical properties measurements were carried out. The results of microscopic characterization showed the presence of cracks inside a minority of glass particles due to ASR, and ASR test indicated that expansion activity remained well below the limit expansion value of 0.15%. The obtained results also showed that, at 28 and 90 days of curing, compressive strength increased respectively by up to 1.63% and 29% for 20% of the incorporated RWG volume rate in concrete; however, beyond this rate it diminished receptively by 30% and 3.2%. This improvement with curing age was attributed to pozzolanic reaction. Regarding density, it reduced by around 5%. Furthermore, thermal conductivity and thermal effusivity decreased respectively by 36% and 8.06% at dry state and they dropped respectively by 44% and 21.28% at saturated state, related to reference concrete RC. It is therefore feasible to substitute high amount of natural sand with RWG to obtain new composite that may be successfully used as structural material in construction building. Full article

Building scaffoldings are temporary structures that are commonly used in the construction industry. A precise determination of the number of building scaffoldings in use is a very complex task. The literature survey showed that there is a lack of scientific studies concerning the estimation of the scaffolding population in the construction industry. This observation gave rise to the need to undertake such research, the aim of which was to develop a model of a neural network set which would in turn enable the number of used building scaffoldings to be estimated. In order to carry out such a research task, an original research methodology was developed, which used the results of empirical research that involved the counting of construction scaffoldings used in selected representative areas of the studied regions of Poland (the research was carried out in the period from 2016 to 2018), and also data taken from a publication of the Central Statistical Office on socio-economic indicators that characterize the analyzed regions (data from 2010 to 2018). The main element of the developed methodology is a set of five MLP neural networks, which was used to predict the number of used construction scaffoldings. The analysis of the sensitivity of the quantitative and qualitative variables of the model showed that they have a significant impact on the final result generated by the networks. The obtained results of the research and analyses showed the size of the population of building scaffoldings used in individual regions of Poland, and also the seasonality of their occurrence. The knowledge obtained on this basis can be used, among others, in economic analyses related to the use of construction scaffolding, as well as in the process of managing occupational safety on scaffoldings. The most important scientific aspect of the article concerns the development of an original methodology for estimating the population of building scaffoldings. Full article
