This paper investigates the spatial characteristics of microstructural phases in relation to fracture toughness Mode-I/II and transport behavior two orthogonal directions lamellar 3D-printed cement paste compared cast counterparts. Using segmentation techniques, it was found that intact materials represent porous interfaces microchannels. A modified partial-notch Brazil-Nut test proposed characterize toughness. new laser-notching process generate a sharp notch account for sensitivity...

This study uses neutron radiography to evaluate the drying of printed cement paste samples containing cellulose nanocrystals (CNCs). CNCs have previously been used in decrease extrusion pressure and increase degree hydration (DOH) samples. Three different mixtures were prepared consisting a plain mixture two types CNCs. The influence sample surface volume ratio (S/V) on their DOH was examined. Exposing 3D immediately after preparation can lead high levels water evaporation, which limit...
Purpose Unlike other materials, textiles associate with aesthetic and mechanical properties such as flexibility removability that allow them to be deployed or folded required which make good candidates for clothing furnishing but also, eventually, applications building. Actually, the should ensure appropriate heat mass transfers between human body its environment in order maintain thermo-physiological comfort. For that, it is important determine water vapor permeability (WVP) of textile....
Abstract Concrete can be susceptible to damage when it is exposed freezing and thawing (FT). It has been shown that the potential for depends on degree of saturation (DOS). When concrete a low DOS, does not show during an FT cycle. However, DOS exceeds specific value (critical DOS), shows resulting from The objective this article measure length change cementitious specimens with varying DOS. hypothesized these measurements used quantify critical (DOSCR) paste FT. Specimens nearly linear...

Abstract This study examines the performance of cementitious systems made using clinker that is typically used to make Type II/V cement, limestone, and supplementary materials (SCMs). The porosity, formation factor, pore connectivity mortars are examined. with ordinary portland cement (OPC), OPC+limestone (LS), limestone (PLC) without typical commercial SCMs (silica fume, fly ash, slag). porosity both PLC OPC+LS approximately 4 % higher than OPC (which contains 2–3 interground limestone)...

Abstract Replacing a portion of the clinker in cementitious systems with limestone is one strategy to reduce greenhouse gas emissions. This study was designed evaluate three performance parameters: heat hydration, drying shrinkage, and flexural strength portland cement (PLC) mixtures. Eighty mortar paste mixtures were prepared using Type II/V ordinary (OPC), PLC, OPC ground (OPC + LS) without supplementary materials (SCMs). The PLC made same commercial facilities raw as (ASTM C150, Standard...
Abstract This study uses neutron radiography to evaluate specimen preparation and test parameters that impact the depth of water penetration in concrete tested under pressure. First, boundary conditions (i.e., dissipation pressure may build up at lower side specimen) on throughout was studied. Second, predrying specimens (at 65°C) examined. Third, is often measured by splitting end permeability test. The use visual assessment quantify compared with measurements determine accuracy inspection....
