Identification of the cement type at the concrete surface with ordinary Portland cement and supplementary cementitious materials with a handheld X-ray Fluorescence analyser

This master's thesis provides knowledge on non-destructive testing of cement and supplementary cementitious materials composition in concrete with a handheld X-ray Fluorescence analyser. <br/><br/>Today, concrete production is responsible for 8% of the world’s CO2 emissions. Recycling concrete material can directly contribute to the reduction of...

The geographical scale of a circular economy: Introducing a framework to determine a relevant geographical scale for the recycling of materials, based on a case study of concrete and copper for the Municipality of Leiden

The implications of a CE and the transition towards it are widely researched. However, there is a lack of research into the relevant geographical scales of CE. Thus, this research aims to present a framework that identifies the optimal geographical scale for the recycling of materials based on various factors. The framework is tested against a...

The impact of recycled cement paste in the development of sustainable mortar

Nowadays environmental issues like the depletion of the natural resources and the pollution of the environment have led many researchers to make new projects about the reuse of waste from construction and demolition again in concrete industry. Among available solutions are the partial replacement of cement with recycled ultrafine particles (RUP)...

Demology: Typology from demolition

Demology project investigates the potential of recycling concrete rubble from demolition of vacant buildings in Southern Limburg in Netherlands. With the "Demologies" research paper, collaborating with local recycling company I analyze typologies that were demolished in Parkstad recently, to compare them later, trace material flow within wider...

Characterisation of recycled concrete aggregates from construction and demolition wastes

Construction and demolition waste form a significant problem in terms of environmental pollution and material depletion. Concrete, as part of construction and demolition waste, is already responsible for 9% of the total anthropogenic carbon dioxide emissions. Consequently, it is important to alleviate the environmental stress of concrete by...
