“…Fine aggregate contents were adjusted in each case to maintain constant volume. Mixing in accordance with guidance provided by Banah UK (Banah, 2011) involved using a motorised table-top mixer to blend the powder and alkaline activator initially, followed by addition of fine aggregate.…”

“…However, as the setting times and rate of strength gain noted for mix 6 were deemed inadequate for rapid repair applications, additional mixes were considered with increasing quantities of calcium-containing materials; an established approach for accelerating geopolymer reactivity (Hunnicutt, 2013). In addition to mix 6, three mixes with 40, 50 and 60% by mass replacements of BanahCEM powder with GGBS (labeled 6-40, 6-50 and 6-60% respectively) were prepared in accordance with the same mixing processes as used in Phase 1 (Banah, 2011).…”

“…Geopolymer cement-based materials have a potential role to play in future road repair and upgrade programmes given their established environmental and performance credentials (McLellan et al, 2011;Davidovits, 2013;Banah, 2014), as well as the emergence of codes covering their properties and use (BSI, 2016). Indeed, previous research investigating the use of geopolymer cement-based products in patching or road repair solutions has generally yielded positive findings.…”

E f f i c i e n t matching o f thickness transducers t o aqueous media r e q u i r e s matching l a y e r s w i t h a v a r i e t y o f acoustic p r o p e r t i e s . Thick f i l m s are a good candidate f o r t h i s . They can be e a s i l y p r i n t e d i n any shape desired, have c o n t r o l l e d thermal expansion and thickness, and adhere w e l l t o substrates and other l a y e r s . To use t h i c k f i l m s as matching l a y e r s , t h e a c o u s t i c impedances must be known.
