This study aims to characterize the behavior of blended concrete, including metakaolin (MK) and quarry dust (QD), as supplementary cementing materials. The study focuses on evaluating the effects of these materials on the fresh and hardened properties of concrete.

MK, a pozzolanic material, and QD, a fine aggregate by-product, are potentially sustainable alternatives for enhancing concrete performance and reducing environmental impact. The addition of different percentages of MK enhances the pozzolanic reaction, resulting in improved strength development. Furthermore, the optimum dosage of MK, mixed with QD, and mechanical properties like compressive, flexural and split tensile strength of concrete were evaluated to investigate the synergetic effect of MK and quarry dust for M20-grade concrete.

The results reveal the influence of metakaolin and QD on the overall performance of blended concrete. Cost analysis showed that the optimum mix can reduce the 7%–8% overall cost of the materials for M20-grade concrete. Energy analysis showed that the optimum mix can reduce 7%–8% energy consumption.

The effective utilization is determined with the help of the analytical hierarchy process method to find an optimal solution among the selected criteria. According to the AHP analysis, the optimum content of MK and quarry dust is 12% and 16%, respectively, performing best among all other trial mixes.

The purpose of this study is to recognise the role of information and communication technology (ICT) tools in different sectors like Education, Health Care, Business, FMCG and Entertainment in the phase of social distancing. This study also attempts to provide a quantitative review of the scholarly literature on this topic.

A comprehensive literature evaluation was undertaken using a database encompassing 150 English-language papers with publication dates ranging from 2019 to 2021. The research profile and thematic analysis are presented through a comprehensive content analysis, resulting in four themes. The study reviews various research articles and reports related to social distancing and opens a discussion on the growing importance of ICT tools during this COVID-19 era.

ICT acts as a surviving tool for the economy by creating a virtual environment and helping people to stay socially connected during this pandemic. There is a lack of empirical evidence to support the facts so further research is required.

There are two drawbacks to the current study. Firstly, this study established a rigorous review methodology in which the researchers opted to exclude any grey literature, non-peer-reviewed articles, books, notes and book chapters from consideration. These sources could have had pertinent literature. Secondly, even after protocol’s rigour and numerous rounds of checks by a team of academicians and researchers, an anomaly may have sneaked into the evaluation.

The current study contributes to the growing literature on ICT tools particularly in this phase of social distancing. This paper highlights the need for future research in this area supported by different statistics.

Rendering digital services have taken centerstage in the current ICT for development discourse. E-Government services are mostly under this discourse with the aim to provide citizen centric services in the public domain. Business and development organizations alike are also investing in developing their own digital infrastructure for rendering services to its stakeholders. This case describes scenario in which a cooperative organization wishes to use digital infrastructure and provide digital services to its farmer members. The cooperative continued investing in ICT since the last couple of decades and constantly upgraded it to ease the transaction and bring efficiency and reduce information asymmetry. This had greatly benefitted the members. However, the cooperative is aware that its communication network built on the wireless medium has its own limitations in introducing new services and integrating its databases and applications. The cooperative took note of “Digital India (DI)” initiatives to provide digital services to rural areas and build an ecosystem to empower the citizens in its governance set up. This DI policy has implicit provisions of better networking protocols with improved bandwidth. The organization has a dilemma to continue with investing its own resources or explore possibility of piggybacking on the DI initiative. The cooperative wished to examine the total cost of ownership in either case and assess the feasibility of converging with the infrastructure created by the government.

The Government Information Technology Policies are increasingly favouring citizens and in favour of shared infrastructure and services. It is worth the examination to evaluate strategies to deploy IT infrastructure and services with optimized cost and better returns in an enterprise. This is far more important for a social enterprise like AMALSAD cooperative (user-owned firm) that has deployed its own IT infrastructure and ITeS. AMALSAD cooperative deployed its IT assets long back and in the meanwhile, the Government policy is in favour of providing services over the internet.

The case serves to help students to understand the theoretical concept of Enterprise information systems infrastructure and services. It brings to the students understanding: the drivers of IT infrastructure to provide digital services; challenges that would make the social enterprise (in this case user-owned firm) to understand the opportunities and challenges of deploying the right digital infrastructure and get services on demand. The case presents the scenarios for the students to deliberate and find answers to the right approach for estimating the total cost of ownership (TCO).

The case situation presents a scenario for digital government services. Most of the customer-facing enterprises including social enterprises are also providing digital services. It is important that such services converge at an optimized TCO.
