This study has demonstrated that artificial concrete pillars can stabilize the active stopes, especially in broader sections of the orebodies intercepted with geotechnical challenges such as high-stress change, spalling, slabbing, sloughing, etc. FLAC3D numerical code was successfully used to...

Specifically, the research undertakes an in-depth analysis of the impact...
Download PDF ↓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;...
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...

A number of research concerns have arisen in the concrete research community on the fire resistance of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) beams, despite their improved mechanical properties at ambient temperature. The traditional experimental approach to performance-based...

Download PDF ↓In Zambia it is estimated that the existing housing stock stands at 2.5 million units catering for about 16 million people. The national housing deficit stands at more than 2 million houses and is compounded by urbanisation. Efforts have so far been made to use alternative building technology...
Download PDF ↓The prevalence of overloading, which is exceeding the maximum load weight, on public transport especially buses in Zambia is very rampant. This is attributed mainly to the fact that there is currently no system to measure and monitor load weight particularly at bus stations apart from few...
