Effect of Viscoelastic Deformation for CA Mortar on Mechanical Responses of Track Structures
KSCE Journal of Civil Engineering, 2021 The viscoelastic deformation of cement emulsified asphalt mortar (CA mortar) can lead to gaps between the mortar and track slab, thereby adversely affecting the mechanical capability and deformation behavior of the track structures. According to the time hardening rate method, a solid model of the China Railway Track System I (CRTS-I) slab track was ...

Crack mitigation in concrete : superabsorbent polymers as key to success? [PDF]
, 2017 Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these

Carbonation Rates of Dry Ca(OH)2 Mortars for CO2 Capture Applications at Ambient Temperatures
Industrial & Engineering Chemistry Research, 2022 The carbonation rates of porous mortars, pellets, and extruded forms of Ca(OH)2 were determined to investigate their suitability as functional materials for direct air capture. Samples of 4-15 mm thickness and porosities between 0.2 and 0.8 were tested by monitoring the progress of the carbonation fronts on time scales from 1 to 500 h. The evolution of
