Mineral Compositions

Cement-based materials (CBMs) such as pastes, mortars and concretes are the most frequently used building materials in the present construction industry. Cement hydration, along with the resulting compressive strength in these materials, is dependent on curing temperature, methods and duration. A concrete subjected to an initial higher curing temperature undergoes accelerated hydration by resulting in non-uniform scattering of the hydration products and consequently creating a great porosity at later ages. This phenomenon is called crossover effect (COE). The COE may occur even at early ages between seven to 10 days for Portland cements with various mineral compositions. Compressive strength and other mechanical properties are important for the long life of concrete structures, so any reduction in these properties is of great concern to engineers. This study aims to review existing information on COE phenomenon in CBMs and provide recommendations for future research.

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.

Reducing Energy

One of the solutions for reducing energy consumption and carbon dioxide emissions in the construction sector is the use of building materials which have a favorable environmental impact. This is possible to achieve by using plant material, e.g., industrial hemp, which absorb large amounts of carbon dioxide during the growth. Instead of cement as a binder there are used alternatively clay or lime modified with industrial waste in the form of pozzolans. The paper presents the possibility of using industrial hemp in the production of composite based on modified hydrated lime. It describes the basic properties of the sample composites such as compressive strength and thermal conductivity based on literature review. The article describes the way of preparing the mixture and the possibility of using the composite for the construction of walls using different techniques.

Holistic Understanding

PurposeWith interest in modern construction methods and new technologies on the rise, construction companies globally are increasingly looking at how to embrace new ideas and engage with new approaches to do things better. A significant amount of work has been carried out investigating the use of individual technologies in the construction sector. However, there is no holistic understanding of the new and emerging technologies that have had proven benefits for construction projects. To fill this gap, this paper aims to provide a landscape of technologies that have been implemented in the construction industry and the benefits associated with their implementation.Design/methodology/approachA systematic review approach and PRISMA guidelines were used. A total of 175 articles published between 2001 and 2020 were identified and thoroughly reviewed.FindingsThe results show that a total of 26 technologies were identified from the literature, and these can be categorised into five groups in terms of their functionality in construction process, namely: (1) data acquisition, (2) analytics, (3) visualisation, (4) communication and (5) design and construction automation. Digital technologies, especially for data acquisition and visualisation, generally appear to underpin and enable innovation in many aspects of construction. Improvements in work efficiency, health and safety, productivity, quality and sustainability have been cited as being the primary benefits of using these technologies. Of these, building information modelling (BIM) appears to be the single most commonly used technology thus far. With the development of computer technology, BIM has constantly been used in combination with other technologies/tools such as unmanned aerial vehicles/systems (unmanned aerial vehicle (UAV)/UAS), geographic information systems (GIS), light detection and ranging (LiDAR) and multidimensional modelling to realise a specifically defined benefit.Practical implicationsThe findings from this review would help construction practitioners identify the types of technologies that can be implemented in different stages of construction projects to achieve desired outcomes, and thus, make appropriate decisions on technology investment and adoption. This review also suggests that to reap the full potential that these technologies offer, aside from construction companies changing their culture and business models, corresponding changes in the construction sector’s operating systems related to building regulation, education and training, as well as contracting and procurement are required.Originality/valueThis paper undertakes a comprehensive systematic review of studies on technology implementation in the construction sector published between 2001 and 2020. It is the first attempt internationally to provide a holistic picture of technologies that have been studied and implemented in construction projects.

Labor productivity, critically important to profitability in the construction, is one of the most frequently discussed topics in the industry, and yet at the same time, is one of the most poorly understood. A literature review was conducted with the aim to identify how labor productivity is studied in the construction industry and what methodological issues exist. The literature review also investigated leading studies in productivity factors in construction generally, and considerations of productivity in relation to the off-site construction (pre-fabrication) sector specifically. The paper outlines general approaches to studying labor productivity in the construction sector. The review found that productivity is usually discussed in the literature under at least three separate topics, namely, the delimitation of construction (what is the precise aspect of construction under investigation), the measurement of productivity (what inputs and outputs are considered), and the identification of the factors that explain productivity. The review found that three issues undermining investigations into productivity in the construction sector were lack of a uniform approach to studying productivity, neglect of relevant variables, and limited generalizability. From this finding, it is recommended that a multi-factor approach is used to analyze productivity in construction. Concerning productivity considerations in relation to the adoption of off-site production approaches to construction, the literature review found that opting to use prefabrication increased overall productivity, led to reduced crew sizes, reduced onsite congestion, reduced cycle time, reduced debris, reduced total structural cost, and improved constructability.

The article explores the role of various financial incentive instruments in optimizing the financial mechanism of logistics development in the construction sector of the economy. The author focuses on the necessary to use a synergistic approach in the study of efficiency issues of two related industries - logistic and construction sectors of the national economy. Positive factors such as convenient location, available transport potential, established logistics system, material and resource base and the potential of domestic producers determine the rapid development of the construction industry, which brings its significant contribution to the development of the national economy of Poland. At the same time, the main factor contributing to the development of construction business is domestic production of construction materials. In this context, it should be noted that the country has developed the potential of its own production of building materials, there is a sufficient fleet of construction machinery and construction equipment, innovative technologies are being introduced, highly qualified personnel, etc. Comprehensive assessment of financial-investment and transport-logistic potentials in the context of the regions, as well as differentiated approach allowed to offer a matrix of financial stimulation tools for the development of logistics in construction in a horizontal and vertical strategy. At a time of intensifying crisis phenomena, simultaneous stagnation of regional development and increasing competition in the globalized world, the issues of selecting effective instruments of financial support for the development of national transport and logistics system and construction sector of economy gain priority importance, as they can generate a significant increase in the gross domestic income of the state budget and become one of the main sources of ensuring Polish competitiveness.
