Utilization of recycled concrete fines and powders to produce alkali-activated slag concrete blocks (2020, background): “, 1999; Krizan and Zivanovic, 2002), sulphate resistance, freeze-thaw resistance and high temperature endurance (Abdulkareem et al., 2013; Fernandez-Jimenez et al., 2007; Fu et al., 2011).”
Use of OPC to improve setting and early strength properties of low calcium fly ash geopolymer concrete cured at room temperature (2015, background): “Low-calcium fly ash-based geopolymer concrete cured in high temperature has been reported to have good mechanical properties in both short and long term tests [10,11].”
Sulfuric acid resistance of one-part alkali-activated mortars (2018, positive): “In previous studies of acid attack on low-Ca AAMs (geopolymers), the presence of silica gel after acid-exposure has been noticed too [12,13].”
Mechanical properties and microstructure analysis of FA-GGBS-HMNS based geopolymer concrete (2019, background): “stress occurred between particles during microstructural development [39].”
Ambient Temperature Drying Shrinkage and Cracking in Metakaolin-Based Geopolymers (2012, background): “Some advantages of specific geopolymer formulas over traditional Portland cements include: higher early compressive strengths [8], improved fire resistance [9], acid resistance [10, 11] and lower embodied CO2 content [12, 13].”
Performance of alkali-activated slag mortars exposed to acids (2012, background): “Differing results have been identified when alkali-activated materials based solely on fly ash are exposed to HCl solution [23], where dealumination of the sodium aluminosilicate binding gel has been identified, along with the destruction of the zeolites formed, independent of the type of activator ”
Sulfate and acid resistance of lithomarge-based geopolymer mortars (2018, background): “Recently, a promising solution has emerged in the form of geopolymer binders which have been reported to have improved resistance to sulfate [27-33] and acid attack [21, 27, 30, 31, 34-39] due to their ceramic-like microstructure.”
