“…Previous results [4] have shown that the performance properties of the mixes depend on the time/temperature profile for curing. Figure 4-3 shows the dependence of E on time and temperature curing profiles for a mix at 0.60 w/cm ratio (GVS118) with a cement concentration of 30 wt % of the premix.…”

“…Recent results [4] demonstrated that it is not only the temperature of curing which is important but also the time/temperature sequence of curing. Therefore, this report also focuses on the impact of the sequencing of time and curing temperature on Saltstone properties.…”

“…This report identifies and quantifies, when possible, those factors that drive the performance properties of the projected SWPF grouts. Previous work has identified aluminate concentration in the salt waste stream as a key factor in determining performance and consequently, a significant variation in the aluminate concentration (from 0.35 to 0.65 M in Phase 12) was investigated in this report [2][3][4].…”

“…The degree of hydration can be estimated by measurement of the heat of hydration through isothermal calorimetry. It turns out that a higher degree of hydration, as reflected by higher heat of hydration, leads to a better product in terms of performance [4]. Therefore, there are competing effects between lowering the heat of hydration in order to reduce the associated temperature increase in the vault and improving the performance properties through higher heats of hydration.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
