Mechanical Behaviour of Geopolymer Concrete under Ambient Curing
Utilisation of fly ash and Ground Granulated Blast Slag as an alternative material in concrete reduces the use of OPC in concrete. Evolution of geopolymer concrete cured at ambient temperature broadens its suitability and applicability to concrete based structures. This paper presents the mix proportions and outcome of an experimental study on the density and compressive strength of geopolymer ...
متن کاملTechBrief: Geopolymer Concrete
Geopolymer concrete—an innovative material that is characterized by long chains or networks of inorganic molecules—is a potential alternative to conventional portland cement concrete for use in transportation infrastructure construction. It relies on minimally processed natural materials or industrial byproducts to significantly reduce its carbon footprint, while also being very resistant to ma...
متن کاملInfluence Of Curing Conditions on Geopolymer Leaching
The worldwide production of PCC fly ash is estimated at achieving 800 million tonnes per year in 2010 [1]. European Union regulations aim at developing new technologies focused on the recycling of these large amounts of PCC fly ash into added-value products. The synthesis of geopolymer binders may be a successful alternative, giving rise to low-cost and environmentally friendly materials with c...
متن کاملLightweight Geopolymer Concrete with EPS Beads
Activation of class F fly ash with the 10 M sodium hydroxide and sodium silicate and its geopolymeric products were analysed under quasi-isothermal mode of DSC, FTIR and TG/DTA techniques. Before adding in concrete, expanded polystyrene beads were prewetted with the styrenebutadienestyrene latex aimed at to improve their bonding with geopolymer. Lightweight mortars/concretes were made from geop...
متن کاملGeopolymer Concrete : a Review of Development and Opportunities
Geopolymer results from the reaction of a source material that is rich in silica and alumina with alkaline liquid. It is essentially cement free concrete. This material is being studied extensively and shows promise as a greener substitute for ordinary Portland cement concrete in some applications. Research is shifting from the chemistry domain to engineering applications and commercial product...
