Historically, mining has been an enormous contributor to the development and sustainability of several societies. The industry despite being a source of wealth is not without risks and challenges, including environmental and operational hazards. These pose a huge challenge to the safety and...

Water is life, essential for human existence, and its importance for individual health as well as the well-being of a nation and access to good quality water cannot be overemphasized. It is therefore believed that a borehole is a hydraulic structure which when properly designed and constructed,...

In Zambia, coarse aggregates for concreting are normally produced by crushing granite, limestone and basalt among other rock types. However, these rocks are scarce diminishing natural resources and henceforth; the need to study other naturally available materials for full or partial replacement;...

The motivation for venturing in alternative jet fuels has partly been due to the elevated level and volatility of the price of Jet A (a kerosene-based aviation gas turbine fuel) and environmental impacts on global climate change and air quality. The model of the annular combustor for the PT6A-27...

In recent years, the world is gradually shifting away from the use of structural concrete in the construction sector. This is due to its retrogressive limitations such as costs, environmental degradation, low strength-to-weight ratio, its susceptibility to cracking. The world is moving towards...

The study aimed at demonstrating the positive outcome of incorporating optimization techniques in the design procedure for designing steel-concrete composite bridges was conducted. Optimization algorithms have the capability of finding optimal or near optimal solutions in complex problems. In...

In practice, cured concrete strength may exhibit strength variation from batch to batch and within batch despite the mixes being of the same proportions and with quality control. On the other hand, structural concrete elements are designed to meet specific characteristic strength. In order to...

The world population continues to grow, with Africa projected to reach 2.4 billion people by the year 2050. This increase in population has resulted in a high demand for goods and services, which has subsequently triggered an increase in demand for mineral resources. Zambia, being a mineral rich...

Despite playing a key role in most economies, building construction contributes significantly to climate change. Buildings consume energy, water, and raw materials, generate waste, and emit potentially hazardous air emissions during the course of their lives. These facts have prompted the...

The mining industry is one of the key economic drivers in Zambia and has tremendously grown since its genesis in the early 1900’s. Zambia is one of the largest copper producers in Africa and the world and this translates to thousands of tonnes of mining waste accumulated over the years. Mine...
