Concrete mixtures have an optimized mix design in view of attaining desired properties. However, after mixing, during further processing, it is typically not possible to further adjust the performance of the fresh and ...
With renewed interest in the optimisation of the hydraulic performance of new and existing culverts, particularly relevant to South Africa’s evolving road network and anticipated climate-induced rainfall changes, this ...

Hydrokinetic turbine deployment in inland water reticulation systems holds untapped
potential for future development in renewable energy. However, prior to implementation, it is
crucial to understand the hydrodynamic ...

Concrete has traditionally been considered as a material with favourable fire resistance.
The development of modern concretes with low permeability has, however, resulted in the
increased occurrence of spalling when ...

Active seismic surface wave tests are tests during which signals are generated by artificial
sources such as sledgehammers, drop weights and fixed or variable frequency shakers.
A number of active seismic surface wave ...
Capturing and understanding the ultimate limit state behaviour of reinforced concrete piles
embedded in soil requires the use of advanced tools or the performance of expensive tests. An
experiment was performed where ...
Ultra-thin continuously reinforced concrete pavement (UTCRCP) is an innovative pavement type that consists of a
50 mm high strength steel fibre reinforced concrete (HS-SFRC) layer overlain on a pavement substructure. ...
Depending on the stress state, mine tailings are generally accepted to be susceptible to static
liquefaction. A common method to assess the in situ stress state of tailings in relation to static
liquefaction susceptibility ...
The design of pile foundations that are expected to develop significant lateral loading is a complex procedure that requires the development of objective and accurate design formulae that will not be based on semi-empirical ...
New methods are proposed for the verification of the presence of superabsorbent polymers (SAP) in freshly mixed concrete and estimation of SAP quantity. The methods are in general based on flushing concrete with excess ...

Tanzania was faced with high incidences of premature rutting failures on their asphalt pavements. Some pavements experienced failures within one to two years after construction/rehabilitation. The objective of this ...
The South African pavement community has shown a keen interest in the use of imaging techniques to characterize the morphological characteristics of aggregates used in road and railway construction. This interest arises ...
Pavement condition evaluation plays a crucial role in assisting with the management of the highway infrastructure. However, the current methods used for assessing pavement conditions are costly, time-consuming, and subjective. ...
This paper presents the results of a centrifuge study in which swell of an expansive clay profile was induced in the
centrifuge. A factor which has previously hindered such research is the time required to induce significant ...
Surface curing of concrete is known to mitigate potential plastic shrinkage cracking. In this research, water and three curing compounds were used to investigate the efficacy of liquid curing on plastic shrinkage cracking ...
Capturing the in-situ state of mine tailings is important in determining its behaviour under
loading for evaluating the risk of failure of tailings dams. Obtaining a high-quality undisturbed sample
through tube sampling ...
