Abstract. The aim of this article is to determine the relation between the phases of the business cycle and changes in prices of factors of construction production. The research covers the years 1994–2012. The dataset applied in the study includes yearly data on prices of the factors of construction production in Poland. All of these data were made available by the SEKOCENBUD. The implementation of the purpose of the study required, firstly, to construct the curve of the economic cycle in the Polish construction industry and, secondly, to determine indicators of changes in the prices of construction production factors and to compare them with the curve reflecting the state of the economic cycle in the construction industry. It was based on the results of a monthly economic situation test, which are published by the Central Statistical Office in Warsaw. A record increase in the prices of production factors in construction was observed during the recovery in 2006–2007. It was caused by the intensified demand for various types of construction services. The deep slump in the construction industry was accompanied by a slight reaction of changes in the prices of construction materials and equipment to the decreasing demand in 2002–2004 and 2008–2012. The results of the study allow to conclude that changes in the prices of production factors in construction are closely related to the situation in the sector, but this relationship is particularly noticeable in the growth phase of the cycle.Key words: economic cycle, building materials and labour, plot of land, real estate

The main international trends in the world market of construction materials and services have been analyzed. The dynamics of world GDP and exports of construction services for the period 2000-2019 has been studied and a conclusion is made on the impact of economic crises on their growth rates. It has been determined that the dynamics of world exports of construction services is characterized by high instability with peaks of growth and decline, and is more sensitive than GDP growth. It has been noted that overcoming the crisis in the export sector of construction services takes more time and occurs with an approximate two-year time lag compared to GDP dynamics. The share of the construction industry in the world GDP by the degree of development has been analyzed. The reasons for the decline in the share of the construction industry in countries with economies in transition have been substantiated. It has been noted that in the developed countries the share of the construction sector is accounted for by real estate management activities related to maintenance, rent, purchase and sale and other transactions with land and real estate. The forecast values of growth of the market of building materials and services till 2030 have been given. The essence of the term «wide construction» has been revealed and the structure of this sector in different countries of the world is shown. The main exporters in the world construction market have been given and the structural distribution of the largest construction companies in the world ranking by country of origin has been analyzed. The dynamics of income level in the construction industry market for the period 2011-2018 has been studied. It has been noted that an important area of the construction sector is the market of roofing and facade materials and the world's largest companies for the production of this type of construction materials have been revealed. Conclusions on the essence of global transformations of the market of building materials and services have been made, and also it has been defined that they are caused by transnationalization of corporate structure of the market, influence of scientific and technical progress and information and communication technologies on world centers as well as the emergence of the concept of «sustainable construction» in the course of humanity for sustainable development.

Primary Materials

<p>The structural engineering community has a strong responsibility to contribute to a more efficient use of natural resources. Nowadays the construction industry is by far the most resource intense industry sector, approximately 40-50% of all primary raw materials are used, which raises the question about the architects and engineer’s accountability. In this context and as a result of the Paris Climate agreement the Dutch government defined the program “Nederland Circulair in 2050”, which states the ambition to use 50% less primary materials in 2030 and to have a full circular economy in 2050.</p><p>One possible approach to achieve these ambitious goals is the application of renewable, bio-based materials in the built environment and to replace traditional, typically cement-based, materials. Already in the past natural building materials, such as timber and bamboo have been used widely, but in recent years new materials came up and provide new opportunities to be used in the construction industry. The authors explored various alternatives, such as hemp and flax fibres, mycelium and lignin-based fibres for composite materials, which will be described with various experimental and realised case studies.</p>

The paper described the network of Natura 2000 sites in Poland, the state of spending funds on Package 4. “Valuable habitats and endangered species of birds in Natura 2000 sites of the Agri-environmental-climate measure implemented under the RDP 2014-2020” (Package 4. of the AECM under the Rural Development Programme 2014-2020) as of 31.12.2017 and also assessed the functioning of farms belonging to beneficiaries of this package against a background of farms from outside Natura 2000 sites, which kept accounts for the Polish FADN in the years 2015-2017. It has been determined that, in Poland, the share of areas covered by the Natura 2000 network in the land area of the country is 19.6%, however, in the case of voivodeships and districts, it is varied. In addition, it has been determined that the state of spending funds under Package 4 has, so far, been PLN 518.8 million and has accounted for 29.6% of total funds spent as part of the AECM under the RDP 2014-2020. It turned out that farms belonging to beneficiaries of Package 4, against a background of other farms which kept accounts for the Polish FADN in the years 2015-2017, were characterised, inter alia, by lower production intensity and lower productivity of production factors. Moreover, those farms obtained lower income per 1 ha of UAA. Analyses have been carried out based on the data from the General Directorate for Environmental Protection, the Central Statistical Office in Warsaw, the Agency for Restructuring and Modernisation of Agriculture, the Polish Farm Accountancy Data Network (Polish FADN) and the Institute of Soil Science and Plant Cultivation National Research Institute.

Foamed Concrete

The key players in the construction industry around the globe are very enthusiastic in producing better construction materials that are cost-effective, durable, excellent thermal insulation, lightweight and long lasting without jeopardizing the environment. One of the best ways in producing such building materials are by incorporating industrial waste materials such as Empty Fruit Bunch (EFB) fiber in foamed concrete (FC). In recent years, the spotlight has been given towards the use of natural fiber reinforced concrete-based materials especially in Malaysia in a quest of economic and environmental upkeep particularly in the construction sector itself. Hence, this study intended to recognize the influence of Empty Fruit Bunch (EFB) fiber of four different contents (0.15%, 0.30%, 0.45% and 0.60 %) by mix volume on thermal properties of FC. There were three densities of 800kg/m3 , 1100kg/m3 and 1400kg/m3 we cast and tested. The mix design of FC (sand: cement: water) is fixed at the ratio of 1:1.5:0.45. The investigation focuses on three parameters which were thermal conductivity, thermal diffusivity and specific heat capacity. Results showed that the addition of EFB in FC plays an important role to improve the thermal performance holistically. The results demonstrated a great potential possesses by the EFB fiber to be utilized in cement-based materials such as the FC mix which is beneficial in reducing the thermal property or the transfer of heat in a produced concrete.

The potential re-use of red mud in the building and construction industry has been the subject of research of many scientists. The presented research is a contribution to the potential solution of this environmental issue through the synthesis of potential construction materials based on red mud. A promising way of recycling these secondary raw materials is the synthesis of alkali-activated binders or alkali activated materials. Alkali-activated materials or inorganic binders based on red mud are a new class of materials obtained by activation of inorganic precursors mainly constituted by silica, alumina and low content of calcium oxide. Since red mud contains radioactive elements like 226Ra and 232Th, this may be a problem for its further utilization. The content of naturally occurring radionuclides in manufactured material products with potential application in the building and construction industry is important from the standpoint of radiation protection. Gamma radiation of the primordial radionuclides, 40K and members of the uranium and thorium series, increases the external gamma dose rate. However, more and more precedence is being given to limiting the radiological dose originating from building materials on the population these days. The aim of this research was to investigate the possible influence of alkali activation-polymerization processes on the natural radioactivity of alkali activated materials synthesized by red mud (BOKSIT a. d. Milici, Zvornik, Bosnia and Herzegovina) and their structural properties. This research confirmed that during the polymerization process the natural radioactivity was reduced, and that the process of alkali activation of raw materials has an influence on natural radioactivity of synthesized materials.

Lca Methodology

The construction industry is increasingly concerned with improving the social, economic, and environmental indicators of sustainability. More than ever, the growing demand for construction materials reflects increased consumption of raw materials and energy, particularly during the phases of extraction, processing, and transportation of materials. This work aims to help decision-makers and to promote life cycle thinking in the construction industry. For this purpose, the life cycle assessment (LCA) methodology was chosen to analyze the environmental impacts of building materials used in the construction of a residence project in São Gonçalo, Rio de Janeiro, Brazil. The LCA methodology, based on ISO 14040 and ISO 14044 guidelines, is applied with available databases and the SimaPro program. As a result, this work shows that there is a substantial waste of nonrenewable energy, increasing global warming and harm to human health in this type of construction. This study also points out that, for this type of Brazilian construction, ceramic materials account for a high percentage of the mass of a total building and are thus responsible for the majority of environmental impacts.

Sustainable Building Materials

PurposeAlthough the adverse effects of construction activities on the environment and the need for sustainable construction practices are recognised in both research and practice, any significant shift in the selection and use of construction materials from the sustainability perspective has not taken place in many building projects. Still, conventional construction materials are widely used in building projects in both developed and developing countries. This study attempts to identify the main barriers to the use of sustainable materials in building projects in an advanced economy such as Australia.Design/methodology/approachThis study adopted a questionnaire survey approach to examine the main reasons behind the low usage of sustainable materials in building projects. Based on the relative importance index, exploratory factor analysis and multinomial logistic regression analysis, the study examined the main barrier measures and barrier factors to the use of sustainable materials in building projects.FindingsThe findings reveal that critical barriers to the use of sustainable materials are related to cost and profit considerations, the unwillingness of the key stakeholders to incorporate these materials into building projects, lack of incentives and government policies. The factor analysis reduced the critical barrier measures into three factors: techno-economic considerations, cost and delay concerns and resistance to use. Furthermore, multinomial regression analysis based on the extracted factors identified techno-economic considerations as the main barrier factor to the use of sustainable materials in building projects.Practical implicationsThe empirical results of this research can inform construction practitioners, organisations and policymakers on how to increase the use of sustainable building materials in the construction industry.Originality/valueIdentification of barriers to the use of sustainable building materials is a prerequisite to improve their uptake and use in the construction industry. The study fills a gap in the existing research on the use of sustainable materials in building projects in Australia.
