Mechanics and durability of surface treated structural foamed concrete
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Lightweight foamed concrete (LWFC) has been around for a few decades and has mostly been used in non-structural applications such as void filling, soil stabilisation, and backfill. Historically, LWFC has ... -
Investigation into fine non-cohesive sediment removal by Swirl/Vortex settling basins at small river abstraction works
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: The often fine non-cohesive and cohesive nature of sediments in South African rivers makes sediment management at river abstraction works rather complex. Sediment removal at river abstraction works is ... -
Derivation of a traffic load model for the structural design of highway bridges in South Africa
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: This study sets out to derive a new traffic load model for the design of highway bridges in South Africa, with novel contributions to the field of bridge traffic loading. The current code for bridge design ... -
The influence of rheology on the cracking of plastic concrete
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Plastic cracking occurs during concrete’s early hours and impairs its serviceability and durability. The early hours refer to the time of mixing to the time around the final set. Concrete possesses ... -
Coupled fully three-dimensional hydro-morphodynamic modelling of bridge pier scour in an alluvial bed
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Local scour at piers has been cited as the main mechanism responsible for the collapse of bridges founded in alluvial beds and yet there is no universally agreed upon design procedure to accurately ... -
Fire Dynamics in Informal Settlements
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: In poor and densely populated countries, the rapid growth in population leads to an increase in landlessness. As a result, the number of people residing in informal settlements is increasing on a daily ... -
Development and optimization of a combined small scale low cost point of use water treatment system
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT:Access to safe drinking water is still limited in many rural and suburban areas of developing countries. Point-of-use (PoU) water treatment is the most feasible solution to fight waterborne diseases which ... -
Computational and Experimental Modelling of Masonry Walling towards Performance-Based Standardisation of Alternative Masonry Units for Low-Income Housing
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: South Africa has a housing shortage estimated in excess of 2 million units. This backlog is being addressed predominantly with the construction of 40m2 low-cost, single storey, detached state subsidised ... -
Rheo-mechanics modelling of 3D concrete printing constructability
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Three industrial revolutions have occurred in the last 250 years that resulted in increased productivity for most economic sectors. This generally improved the standard of living for all individuals. ... -
Determination of the critical incipient failure conditions for angular riprap dumped on wide & steep trapezoidal channels
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The main objective of this thesis was to determine the critical MN that defines the incipient failure conditions of angular riprap dumped on wide and steep trapezoidal channels. A total of 32 physical ... -
Aspects of self-cementation when applied in roads
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Worldwide, the growing volumes of traffic have led to the increase in an expanding infrastructure that must be continually maintained. Congruent with these developments are undesirable environmental c ... -
South African novice drivers: exploring hazard perception development during the learner driver training phase
(Stellenbosch : Stellenbosch University, 2019-04)Introduction Novice drivers, worldwide, have an increased risk of being in a fatal crash. Despite reliable crash data, indications are that South African novice drivers are no exception and that novice drivers form part ... -
Modelling outdoor water use of homes in gated communities
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: Gated communities are commonly referred to as residential estates, or common interest housing developments. The homes in a particular gated community are often closed off to the general public by means ... -
Investigation into flow-induced vibrations of piano key weirs
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: This thesis considers the transient behaviour of piano key weirs (PKW) from a hydrodynamic and structural perspective. Their geometry makes them very rigid structures, however, there are thinner components ... -
Modelling breakthrough curves and investigating the impact of models and numerical properties on parameter estimation
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The research investigated and applied several Eulerian numerical methods of the advection-dispersion model (AD-Model) for the analysis of concentration-time curves, also known as breakthrough curves (BTCs), ... -
Health and safety management and performance among construction contractors in South Africa
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The construction industry is of vital importance to the economies of nations. It employs about seven percent of the global workforce but accounts for between 30 and 40 percent of all work-related ... -
Investigating the link between the built environment and the incidence of pedestrian crashes in Cape Town, South Africa
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Pedestrians are the most vulnerable road users in the road environment, particularly in the developing world. To gain a better understanding of pedestrian crash causation, the built environment has been ... -
Numerical modelling of alkali silica reaction in concrete dams
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Dams are important infrastructure components and an asset for any country. Past earthquakes have highlighted their vulnerability to damage and even failure which can have major socio-economic consequences, ... -
Reliability-Based Design in Geostructural Engineering
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Current standards used in South African geotechnical design practice follow the partial factor limit states design approach. Although partial factors used in this approach are calibrated for standardised ... -
