“…The classic E-modulus tests served only as a reference value to assess whether the EMM-ARM method was providing realistic values when performing isothermal tests at different temperatures. Considering the use of EMM-ARM methodology for measurement of E-modulus evolution since early ages of cement-based materials was already validated and established in previous works (Delsaute et al 2016;Granja and Azenha 2017), including at different isothermal conditions (Silva et al 2018), it was deemed enough to perform such a validation in a single age, as any potential negative effects of the different isothermal conditions on hydraulic cements would likely be evident in the overall evolution curve and at any age.…”

“…The EMM-ARM methodology has been used to study hydration kinetics of cementitious materials (Maia et al 2011(Maia et al , 2012 and successfully applied in various materials, such as concrete (Azenha et al 2010), mortar (Ramesh et al 2019), cement paste (Azenha et al 2012), soil-cement (Silva et al 2013) and epoxy resins (Granja et al 2015). If performed in different isothermal conditions, the data produced during EMM-ARM tests can be suitable for the estimation of the apparent activation energy evolution as hydration progresses and E-modulus develops, as already explored in lime-treated-soils and epoxy resins (Benedetti et al 2016;Silva et al 2018).…”

The influence of temperature on the hydration of cementitious materials has been traditionally modelled using the maturity concept and Arrhenius law. This approach yields a single material property, called apparent activation energy ( a E ), that describes the whole temperature dependence. Determining a E experimentally has sparked controversy, such as whether the different properties (e.g., compressive strength, tensile strength, E-modulus) exhibit different a E , whether a single a E value exists for the entire hydration process, or whether cement paste and concrete possess the same a E . Furthermore, studies measuring a E from elastic modulus measurements are truly scarce, likely due to experimental challenges with measuring this property at early-ages. This work investigated the influence of temperature on the elastic modulus evolution of cement paste and concrete. A single mix for each material was tested with the EMM-ARM (Elasticity Modulus Measurement through Ambient Response Method) methodology under three different isothermal conditions. The resulting elastic modulus evolution curves were used to derive a E evolution curves from two traditional computation methods: the 'speed' method and the 'derivative of speed' method. Results showed that the elastic modulus evolution of both materials initially presented a constant a E , independent of temperature and hydration development as preconized by the classical Arrhenius law. However, as hydration progressed to later stages, the activation energy exhibited evident dependencies on both temperature and hydration levels. Cement paste and concrete consistently exhibited different a E values throughout hydration, with concrete having higher values. The use of the a E curves to superimpose the different experimental elastic modulus evolution curves by means of the equivalent age concept led to near-perfect superpositions, strengthening the validity of this concept when applied to elastic modulus evolution.

“…In the other hand, in combination with dynamic compaction, limetreatment is an efficient way to significantly improve the engineering properties of fine-grained compacted soils [4,26,32] with applications in road subgrades [7,24,31] or hydraulic works [18,17,23]. Concerning the stabilization of the soil, lime reacts mostly with the clay fraction N. Poncelet and B. François [16].…”

“…Available literature data on the thermal conductivity of compacted treated materials are scarce, while treatments with lime or hydraulic binders modify significantly the soil mineralogy [13,14]. The microstructure of treated soil is also significantly different from the microstructure of the untreated soil [15,16] and is impacted by temperature [17,18]. Moreover, the hydro-mechanical behaviour of treated soils is highly time-dependent due to the processes induced by the presence of lime and/or binder.…”
