An Empirical Examination of Antecedents of Burnout in Indian Construction Professionals

Infrastructure projects entail extremely demanding working conditions, often with scant resources or support. When early career construction professionals are exposed to such pressures on a sustained basis, they are likely to experience burnout. Accordingly, this study sought to examine the antecedents of burnout, employing the job demandsresources model. An empirical study with responses from 207 early career engineers and managers employed in infrastructure projects in India largely support the conjectures. As hypothesized, negative association was found between perceived organizational support and job autonomy (both resources) and burnout. Further, positive association was found between work-family conflict and stakeholder management (both demands) and burnout. However, hypotheses about emotional intelligence (resource) and role ambiguity (demand) were not supported. Results of the study are discussed with respect to their implications for research and practice. Limitations are acknowledged.

Development of Self-Sealing Concrete by Using Superabsorbent Polymer
Devang Patel , Hardik Solanki and Suhasini Kulkarni
Super absorbent polymers (SAP) are new and promising multipurpose chemical admixture for concrete. Superabsorbent polymers can absorb 300 to 400 % of water from its weight. Due to this characteristic, the SAP is also used in concrete to reduce the flow of water in a crack by self-sealing. Hydrogel is one of the types of super absorbent polymers. This SAP is mainly used for agricultural purpose. In this study, cylindrical concrete sample of M25 grade was casted with different dosage of SAP. The main objective of this research is to reduce the flow of water penetrate in the concrete by developing self-sealing concrete. The two types of cracks with width 1.5mm and 2mm are used in this research. This research is focused on 5%, 4%, 2%, 1.2% and0.8% use of hydrogel (SAP) by the weight of cement. In this experiment, SAP is used as an admixture to improve its water tightness properties in concrete. These cylinder shaped samples were purposefully wrecked into two equal pieces to create an induced concrete crack. A special experimental setup was prepared for the research. The result of this research shows the optimum dosage of SAP and its effect on properties of concrete. The research also compares the strength of concrete cube of M25 grade and cement mortar cube of ratio of 1:3, 1:4, 1:6 with the use of hydrogel SAP. The use of high dosage of SAP can heal the crack in both crack width sizes. However, use of high dosage of SAP also reduces the compressive strength.
Project Management Practices in Indian Smart Cities: Insights from a Street Re-design Project
Tushar Jadhav and Rahul Deshpande
The smart cities mission is a major flagship programme by the Government of India to develop 100 smart cities across the country. There is adequate literature available on smart cities and its associated technologies. However, there are no studies that would address the development of smart cities from the perspective of project management. In this paper we attempt to identify the extent to which project management practices are used in execution of smart city projects in India. Case study approach was selected to identify the issues in a particular smart city project.

Impact of COVID-19 on Entrepreneurship in Construction Sector in India
Rahul Goel and Sarbesh Mishra
Entrepreneurship as a career is considered to be a multidimensional activity in which various aspects of a business are to be coordinated to achieve the desired result. Business is generally considered to be affected by various developments in political, economic, social, or technological fields. However, rarely are the times when a business is impacted by any of the developments in the Biological field. The discovery of COVID -19 in Wuhan city of China has made a significant impact on almost all economies of the world. It was first found in China in December 2019. The Corona Virus has spread now almost in all major economies of the world. Being highly infectious and tending to spread from one person to another very fast, it has led to the development of new norms like social distancing to restrict the spread of COVID-19. As it does not have any specific treatment or vaccine to protect the humans from it, almost all governments around the globe have opted for total lockdown and social distancing as the immediate measures to fight against the deadly disease. This has led to a severe setback in almost all sectors of the economy. The construction sector of India, which is primarily a labor-intensive sector, and is highly dependent on the continuous supply of raw materials, has also been hit severely. Impact on the construction sector will also lead to a cyclic effect on the 250 allied industries which are directly affected because of any change in it. This paper is an attempt to understand the impact of COVID-19 on entrepreneurship in the construction sector with special reference to real estate projects.

Geopolymer Composites for Smart and Sustainable Infrastructure: A Review
Jyotirmoy Mishra , Bharadwaj Nanda and Sanjay Ku. Patro
In order to achieve the goal of sustainable development, we require sustainable infrastructure. The demand for sustainable infrastructure will keep on rising as the traditional cement-based building materials are not considered to be sustainable enough due to the huge carbon footprints from the cement industry. Geopolymer composites such as mortar and concrete are low-carbon, cement-less construction materials, which are inorganic polymers made from alkali activation of industrial wastes, rich in aluminum and silicon. Past literature suggests that geopolymer composites emit up to 70% less carbon dioxide than cement-based composites. This paper presents a review of various geopolymer composites, specifically mortar and concrete, made from some of the contemporary industrial wastes. The compressive strength properties of each of these waste-derived geopolymer composites have been highlighted, along with various applications of geopolymer based construction materials for smart and sustainable infrastructure development.
