(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: The testing of new construction materials and configurations is extremely important in order to protect property and lives. However, there are limited facilities available on the African continent for ... -
Energy dissipation at uncontrolled high dam spillways by flare
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Spillways have been used for approximately 3500 years to discharge water from dams. A growing world population has made the construction of dams a matter of critical importance. Several different types ... -
Culvert blockage caused by boulders in the Western Cape and the development of mitigation measures : physical model study
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Culverts are widely used as drainage structures to allow streams to traverse a roadway in a controlled manner. Due to the reduced flow area of a culvert, culverts can be seen as a constriction in a ... -
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 ... -
Invloed van vloeibare kuringsmetodes op plastiese krimpkrake van beton
(Stellenbosch : Stellenbosch University, 2020-04)AFRIKAANSE OPSOMMING: Die kraak van beton is ‘n algemene probleem wat kan lei tot verlies aan duursaamheid, dienslewe en estetiese waarde. Tog is daar verskeie beskikbare maniere om die ontwikkeling van krake te verhoed ... -
Developing a new model to predict the diurnal water demand pattern for residential areas subjected to formal intermittent supply in South Africa
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Intermittent water supply (IWS) is one of the most common methods of water demand control under water scarcity conditions, however the implementation of IWS has many negative impacts and is not recommended ... -
Interaction between clinker, calcium sulphate and superplasticisers in cement-based mixes
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Modern cement contains an increasing number of extenders, resulting in a variation in the composition of the cement, while the use of chemical admixtures is also becoming a normal addition to a modern ... -
Understanding and benchmarking suppression systems for post-flashover informal settlement fires
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Currently there are more than one billion people residing in informal settlements worldwide. The increasing number of people residing in informal settlements worldwide is attributed to an overall rise in ... -
An assessment of the in-situ state and staged construction of a tailings storage facility in South Africa
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Due to the sizeable dimensions, in cases of failure, tailings dams represent high-risk not only to the mining operations but also to surrounding communities and the environment. The recent catastrophic ... -
Influence of spray jet technology on bond strength of asphalt and pavement life
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Tack coats promote bonding between pavement layers. This allows the pavement structure to behave as a single unit whilst providing adequate strength. The lack of poor bonding leads to a pavement structure ... -
A stochastic, daily time-step model for the conjunctive use of surface water, groundwater, desalination and water reclamation for municipalities
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: South Africa has a broadly-developed water infrastructure based mainly on surface water, localised groundwater and occasional desalination as resources. However, the most suitable sites for surface water ... -
A study of safety and security of pedestrians travelling towards the Bellville, Claremont and Mitchells Plain public transport interchanges in the Cape Town municipal area
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Poor levels of safety and security have continued to increase, the state of public transport continues to deteriorate, while 5.2 million commuters are challenged by this daily. The implementation of NMT ... -
Evaluation of the influence of aeration on the discharge capacity and flow induced vibrations of Piano Key Weir spillways
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: A Piano Key Weir (PKW) spillway is a popular option for increasing the discharge capacity of existing dams due to its high discharge efficiency compared to linear and traditional labyrinth weirs, as ... -
Potential for recycled concrete aggregate stabilisation with bitumen emulsion and foamed bitumen
(2020-03)ENGLISH ABSTRACT: Bitumen stabilisation is a technology used to improve the strength properties of any aggregate, which is also environmentally friendly. The method of stabilisation requires less energy in comparison to ... -
Rheological performance of seals in South Africa based on binder ageing considerations
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Ageing is a fundamental phenomenon that affects the durability and performance of bituminous binders in a pavement. Ageing increases the risk of premature pavement failures whilst reducing the material ... -
Establishing and applying road classification and access management techniques on Bird street in Stellenbosch, South Africa
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Bird Street is one of the roads in Stellenbosch with the slowest movement of traffic and the highest level of congestion during peak hour periods (06:00 to 09:00 and 16:00 to 19:00). The optimum functioning ... -
Rock-structure interaction : improving the consistency in the finite element modelling of rock foundations for bridges
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: The design and modelling of foundations crosses two civil engineering disciplines, namely structural- and geotechnical engineering. The structural engineer goes into great detail when sizing foundations ... -
Changing the permeability, mineral and soil structure of clay soil with chlorine dioxide
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Clay particles have small particle sizes. With the addition of water, the change in volume is greater in clay soils than coarse grained soils. When clay soils are mixed with a coarse-grained soil, the ... -
The Influence of pile batter angle, soil unit weight and soil moisture content on the ultimate axial tensile load capacity of micropiles
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Battered piles are commonly adopted to resist overturning moments acting on the foundations of high-rise buildings and tower structures. Urbanization at an exponential rate is leading to an increase in ... -
