Fabrication, microstructural analysis and structural performance of green Geo-polymer concrete with textile reinforcement

MSc Thesis

Ordinary Portland cement (OPC) is a commonly used binder for concrete. The contribution of OPC to greenhouse gas emissions was estimated to be 1.35 billion tons per annum or approximately 7% of the total greenhouse gas emissions to the earth’s atmosphere and approximately 95% of this CO2 was produced during the fabrication of cement for concrete production. This calls for the development of alternate binders to OPC aiming at to reduce the environmental impact of construction, use of greater proportion of waste pozzolan, and also to improve concrete performance. Geopolymer is one of these alternate binders which attracts considerable attentions because of its early compressive strength, low permeability, good chemical resistance and excellent fire resistant behavior. Because of these advantageous, the geopolymer is considered as a promising candidate to replace OPC for developing various sustainable products in making building materials, concrete, fire resistant coatings, fibre reinforced geopolymer composites and waste immobilization solutions for chemical and nuclear industries. Geopolymer is environmentally-friendly material whose manufacturing creates less CO2 emission than that of OPC. It was reported that the use of geopolymer could bring down the overall CO2 emission by up to 64% in comparison with the use of OPC. This master thesis focuses on the fabrication, microstructural analysis and structural performance of fibre reinforced polymer (FRP) composites reinforced Geo-polymer composites.

The tasks include:

  • Literature review of the fabrication of geopolymer and FRP textile
  • Fabrication of geo-polymer with different mix design formulates and FRP textile reinforced geo-polymer
  • Thermal stability of Geopolymer and FRP by thermogravimetric analysis (TGA)
  • Morphology analysis of FRP reinforced geopolymer using scanning electronic microscope (SEM)
  • Compression, flexural and interfacial bond tests of geopolymer-textile hybrid components
  • Small-scale fire tests of Geopolymer-textile components

Knowledge of chemical and material science; Basic knowledge of different testing machines; English language - communication skills; Self-motivation

The final thesis report can be written in English or in German. Because the mentor mainly speaks English, it is most useful for the student, to speak at least some English.
