-
(University of Pretoria, 2018)Hybrid fly ash cement is a binder with a composition between that of pozzolanic fly ash cement and alkali activated fly ash cement. Its production requires less cement clinker than ordinary Portland cement, facilitating a ...
-
(University of Pretoria, 2019)Ultra High Performance Concrete (UHPC) is an ultra-high strength concrete with superior mechanical properties. The high compressive strength (more than 150 MPa) and high ductility make UHPC a suitable material for manufacturing ...
-
(University of Pretoria, 2017)Ultra Thin Continuously Reinforced Concrete Pavement (UTCRCP) is an innovative road paving technology that can have significant advantages over traditional road paving techniques. Full scale testing has shown that UTCRCP ...
-
(University of Pretoria, 2007-01-12)Foamed concrete is produced when a foaming agent IS added to cement-based slurry consisting of cement, water, cement extender and filler. This lightweight building material can contribute significantly to uplift disadvantaged ...
-
(University of Pretoria, 2015)Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP) is an innovative pavement type that has the potential to fulfil South Africa’s pavement repair strategy requirements. It consists of a thin high strength concrete ...
-
(University of Pretoria, 2020-09-28)The mechanism of cave mining propagation still requires a better understanding to be attained outside the industry-accepted Duplancic conceptual model. While this model suggests a continuous damage profile to be followed ...
-
(University of Pretoria, 2017)Civil structures are founded on or within soil. Understanding the interaction of a structure with the soil it is founded on or within is vital for designing and constructing structures that will be safe and functional for ...
-
(University of Pretoria, 2021)An ultra-thin continuously reinforced concrete pavement (UTCRCP) has a thickness of less than 75 mm while thin concrete pavements has a thickness of less than 150 mm thickness. Both pavements are reinforced with steel ...
-
(University of Pretoria, 2011-10-14)An innovative pavement system known as Ultra Thin Continuously Reinforced Concrete Pavement (UTCRCP) was recently developed in South Africa. The technology is currently being implemented on some major routes in the country. ...
-
(University of Pretoria, 2011)The ever-increasing demand for energy due to industrialization and population growth necessitates the combustion of more coal , which results in enormous fly ash production. The scarcity of pot able water as well as high ...
-
(University of Pretoria, 2015)Foundation systems are some of the most widely used structures in civil engineering. The design thereof is governed by two failure mechanisms, either bearing capacity failure or settlement failure. Generally, the governing ...
-
(University of Pretoria, 2023)Although the construction of integral abutment bridges (IAB) is simplified as the members are all cast monolithically with each other, the soil-structure interaction between the abutments and the retained soil significantly ...
-
(University of Pretoria, 2006-07-20)In this dissertation the effects of different types of Pulverized Fuel Ash (PF A)-types on the workability of cementitious pastes containing relative large amounts of PF A were investigated. The different types of PF A ...
-
(University of Pretoria, 2017)The stress-strain distribution in flexural compression has been at the forefront of investigation ever since the 20th century. The original formulation of the flexural stress-strain distribution and the subsequent development ...
-
(University of Pretoria, 2020)The Soil Water Retention Curve (SWRC) of different soils has been researched thoroughly by multiple Geotechnical Engineers. The interpretation of the SWRC for a specific soil leads to the identification of certain properties ...
-
(University of Pretoria, 2020)In South Africa, as much as 33 million tons of ash, a waste product of burning coal, are produced per year. Of the total ash produced, just over 8% is sold for utilisation, the remainder of which is disposed of in landfills ...
-
(University of Pretoria, 2020)Pile foundations are extensively used to support various structures that are constructed in soft/loose soils, where shallow foundations would be considered ineffective due to low bearing capacities and large settlements. ...
-
(University of Pretoria, 2008-05-05)Steel Fibre Reinforced Concrete (SFRC) is defined as concrete containing randomly oriented discrete steel fibres. The main incentive of adding steel fibres to concrete is to control crack propagation and crack widening ...
-
(University of Pretoria, 2020)The overall objective of this study was to develop an optimised Ultra-High-Performance Concrete (UHPC) matrix based on the modified Andreasen and Andersen optimum particle packing model by using available South African ...
-
(University of Pretoria, 2020)Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP) is an innovative pavement type that has the potential to fulfil South Africa’s pavement repair strategy requirements. It consists of a 50 mm thick High Strength ...
