Geopolymer has emerged as a sustainable alternative to conventional ordinary Portland cement (OPC) binder in construction. Geopolymer binder exhibited superior mechanical, durability and fire resistance properties and significantly lower carbon footprint that its OPC binder. To improve the brittleness of geopolymer various types of both short and continuous fiber are added to increase the tensile and flexural strength, ductility, toughness and energy absorption capacities of fiber reinforced geopolymer composites. This special issue will present original research articles on the fiber reinforced geopolymer composites as well as review article on this emerging topic. Researchers currently working on fiber reinforced geopolymer composites around the world are invited to showcase their research by submitting their original or review article in this special issue of journal of “Fibers”.

Title: Tensile behaviour of fibre reinforced alkali activated composites
Authors: Nuno Cristelo, Victor M.C.F. Cunha, Filipe Almeida
Abstract: The technological evolution of the construction industry has yet to tackle one significant issue, which is the fact that cement production is responsible for almost 10 % of the total CO2-eq release. To reduce, in the near future, the consumption of Portland cement, environmentally viable and economically sustainable solutions need to be developed. These will include the incorporation of large volumes of industrial waste, like fly ash from the combustion of coal in power stations. One possible way to take advantage of the properties of these residues, possibly the most promising, is the technique known as alkaline activation, capable to produce aluminosilicate-based materials with excellent physical and chemical properties, and a wide range of applications. Nevertheless, one of the drawbacks of these composite materials is their brittle behavior. Thus, the present work aims to study the effects of reinforcing alkali activated composites with sisal fibers. For that, alkali activated fly ash F was mixed with fibres, and resulting response was measured through uniaxial compression tests and indirect tensile tests. Four different fibre contents (0%, 0.2%, 0.6% and 1%), two sizes (13mm and 50mm) and four curing periods (14, 28 , 56 and 112 days) were considered. Results confirm that the behaviour of alkali activated composites is enhanced with the addition of sisal fibres.
