Tailings are discharged directly into rivers, valleys, and surrounding due to the absence of tailing containments at artisanal and small-scale mining sites leading to environmental pollution. Synthetic liners are expensive, however, compacted natural soil has been found to be more cost-effective. This study aimed to undertake a laboratory evaluatio...
Purpose
This article aims to investigate the various applications of gamification practices in the construction industry, with a focus on improving safety and quality, project management, innovation and productivity and workforce development.
Design/methodology/approach
A comprehensive literature review was conducted to identify several constructi...
Purpose
The purpose of this article is to assess the extent to which environmental economic practices are recognized and implemented in developing countries, with a specific emphasis on the Nigerian construction sector.
Design/methodology/approach
To examine the extent of awareness and usage, a quantitative research approach was adopted with close...
A non-linear sequentially-coupled thermal–mechanical finite element (FE) paradigm that reasonably tracks the coupled fire-structure response of ultra-high performance fibre reinforced concrete (UHPFRC) beams subjected to the ISO 834 fire is established and presented. A fire resistance parameter study is conducted on UHPFRC beams via the developed F...

Slim floor systems possess favourable thermal and thermo-mechanical behaviour in comparison with the traditional steel-concrete composite beams. Despite a recent surge in their usage in the construction sector, there is limited research on their performance at elevated temperatures. Due to limited investigations, there is a lack of fire design guid...
This paper presents discussions regarding informal settlement (also known as slums, shantytowns, favelas, etc.) fire dynamics and lessons learnt from full-scale tests on dwellings, typically referred to as “shacks” in South Africa. Smoldering and flaming fire setups are considered, and both timber and representative household contents are used as f...
Informal settlements, which have little or no legal status and no official planning remit, such as slums, shacks and favelas, are exposed to an extensive risk of fire. Due to flammable construction materials of the dwellings, the combustibility and flammability of the materials of dwelling furnishings and the proximity and density of these settleme...
On 11 March 2017, a large fire ravaged through the Imizamo Yethu informal settlement in Cape Town, South Africa, killing four people. A total of 2194 informal dwellings were destroyed, and over 9700 people were displaced. This paper presents an analysis of the spread of the fire and factors that contributed to the conflagration. This work is based...
Purpose
Informal settlements are inherently unstructured in nature, lack adequate services, regularly have high population densities and can experience social problems. Thus, fires can easily propagate rapidly through such areas, leaving thousands homeless in a single fire. The purpose of this paper is to present an appraisal of various interventio...
Internationally, informal settlements (also known as slums, favelas, shantytowns, ghettos, etc.) are expanding rapidly which have been associated with numerous large fires (where more than 10,000 people can be left homeless in a single disaster [1]), and an increase in fire related injuries and deaths. As a result of an increase in fire related inc...
Purpose – The purpose of this study is to investigate the effect of the airgap on thermal behaviour and structural response of fabricated slim floor beams (FSFBs) in fire.
Design/methodology/approach – A detailed analytical model is established and validated by replicating the response of FSFBs. The validated finite element modelling method is then...
Ultra-high performance fibre reinforced concrete is one of the construction materials that is still in need of more research to evaluate its performance under fire, particularly regarding explosive spalling. In this study, the effect of curing temperature on the fire resilience of ultra-high performance fibre reinforced concrete (UHPFRC) has been t...

This paper presents the residual strength of ultra-high performance fibre reinforced concrete (UHPFRC) containing both steel and polypropylene fibres. Previous results have shown that UHPFRC cured at different temperatures differ in mechanical properties. This experimental investigation compares the influence of the cold and the hot curing temperat...
In this paper, we report on our investigation regarding the influence of the thickness on the thermal and fire response characteristics of two types of composite materials. For this purpose, carbon fibre-reinforced epoxy and glass fibre-reinforced phenolic resin samples, differing in thicknesses, were chosen. The primary aim was to investigate the...
Ultra-high performance fibre reinforced concrete (UHPFRC) is a relatively new construction material. In comparison with conventional high strength concrete UHPFRC usually does not contain coarse aggregates larger than 6–7 mm in size. This paper presents the outcomes of an experimental study of UHPFRC beams subjected to four-point loading. The effec...

Ultra-high performance fibre reinforced concrete (UHPFRC) is a new class of concrete with favourable mechanical properties over ordinary concrete. A great amount of research relating to the performance of UHPFRC at room temperature has been conducted, but its behaviour at elevated temperatures has not been sufficiently explored. This study presents...
Ultra-high performance fibre reinforced concrete (UHPFRC) is a relatively new construction material that possesses favourable mechanical properties over ordinary concrete. Although enormous strides have been achieved in understanding the performance and behaviour of UHPFRC at ambient temperature, there’s little literature and experimental data on t...
