The importance of this sector is evident in its substantial contribution to Tanzania's gross domestic product (GDP). According to the Tanzania National Bureau of Statistics (NBS), in 2015 the construction sector accounted for 13.6% of the country's GDP, totaling $6 billion. Furthermore, during 2016 and 2017, the Government of Tanzania allocated TZS 5,470 billion, equivalent to 25.4% of the total budget (excluding public debt service), to support infrastructure development projects. These statistics highlight the central role of the construction sector, not only in Tanzania but also in the global context. Say no to plagiarism.

The construction sector, worldwide, is known for its resource-intensive nature, high energy consumption and significant waste generation, all of which contribute to environmental degradation and climate change. In response to these challenges, green building technology has emerged as a beacon of hope for sustainable building practices. Green buildings are conceived and designed with the overall goal of minimizing their ecological footprint, promoting energy efficiency, conserving vital resources and dramatically reducing waste production. In the face of global climate change and the urgent need for sustainable development, green building practices have gained momentum. At the heart of the green building movement is the innovative use of eco-friendly building materials. Among these materials, green concrete has emerged as a noteworthy contender in the quest for sustainable construction. Green concrete is distinguished from conventional concrete primarily by the incorporation of industrial byproducts, such as fly ash and slag, as a replacement for traditional cement. These industrial by-products, which would otherwise end up in landfill, are repurposed to improve concrete's environmental credentials, making it a responsible and sustainable choice. Green concrete: a sustainable solution Green concrete represents a testimony to the evolution of the construction sector towards more environmentally responsible practices. Its properties and behaviour, when compared to traditional concrete, reveal a compelling reason for its adoption in the Tanzanian building landscape. One of the defining characteristics of green concrete is its commitment to reducing environmental degradation. By incorporating industrial byproducts such as fly ash and slag as cement substitutes, green concrete significantly reduces carbon emissions and minimizes its carbon footprint. This is a crucial aspect given that the production of traditional cement, one of the main components of concrete, is associated with significant energy consumption and the release of carbon dioxide (CO2). Green concrete, therefore, offers a practical solution to reduce the environmental impact of the construction sector, in line with global sustainability objectives. Furthermore, green concrete boasts a portfolio of properties, 43, 719-729.
