DOI: 10.1016/j.cemconres.2019.05.005
Abstract: Abstract In hardened cement paste (C-S-H gel), water intercalated between the C-S-H layers can be adsorbed and desorbed by varying relative humidity. Sorption in the interlayer space between the C-S-H sheets is supposed to be… read more here.

DOI: 10.3390/ma15093384
Abstract: Adherent hardened cement paste attached to recycled concrete aggregates (RCA) generally presents a higher porosity than natural aggregates, which induces a lower porosity in the properties of RCA. The characterization of the adherent hardened cement… read more here.
