Andrade Borges, Emilia (author)
This thesis addresses the topic of ongoing (excessive) deformations observed in balanced cantilever prestressed concrete bridges all over the world. Many authors attribute this behavior to the time-dependent phenomena of creep and shrinkage. Balanced cantilever bridges are classified as creep-sensitive structures, and for that reason, a detailed...

This graduation project investigates the integration of green concrete in construction projects for sustainable development. Green concrete, characterized by the use of recycled materials, reduced cement content, and environment-friendly processes, is crucial in minimizing the construction industry's environmental impact. The study addresses the...

Upscaling of two geopolymer concrete mixtures in an individual prestressed girder in self-compacting geopolymer concrete (SCGC) with a topping layer cast in-situ by a ready-mix geopolymer concrete provider. The objective is to study the different material properties of the mixtures, determine their impact in the structural performance and define...

After water, concrete is the most used substance on the planet. Approximately three tonnes of concrete is produced per person annually (Gagg, 2014). Traditionally, large amounts of Ordinary Portland Cement (OPC) are needed for the production of concrete. The production of OPC is very energy intensive and therefore a major generator of carbon...

Global climate change has been a huge matter of concern today. While there are several factors that contribute to greenhouse gases, adversely affecting the planet, CO2 emission is one of them. It is said that 8% of total carbon dioxide emission is caused due to the production of Ordinary portland cement used for concrete in...

Currently, Ordinary Portland cement (OPC) concrete accounts for the world's 8-10% anthropogenic carbon/ greenhouse (GHG) emissions, where 90-95% of the emissions are due to the production of OPC. A 200% increase in OPC demand is projected by 2050 from 2010 levels. Therefore, it is urgent to reduce these emissions arising from its production....

This research aims to improve the sustainability of Dutch prestressed concrete railway sleepers. Approximately 100.000 to 200.000 sleepers are used every year, corresponding to 12.000 to 24.000 tonnes of concrete. This will be done by replacing cement with an alkali-activated binder. The cement industry is responsible for approximately 5 to 7%...

In floors without dilation joints drying shrinkage cracking can occur. Shrinkage reducing agents (SRAs) can reduce the amount of drying shrinkage and improve the durability of the concrete structure. The mechanism of shrinkage reduction and the influences on the hydration process and development of mechanical properties of the SRA Sika Control...
