Mitigation and Evaluation of Alkali-Silica Reaction (ASR) and Freezing and Thawing in Concrete Transportation Structures
… and severely during exposure to F/T. The interstate pavement underwent less deterioration as the incorporation of some Class C fly ash limited the development of ASR, and improved the durability to F/T. A three-year field test of various treatments applied to concrete barriers indicates silane …

Concrete at high temperatures: hygro-thermo-mechanical degradation of concrete
… of the slip flow effect is included and several state equations, including relative permeability and saturation vapour pressure, are adopted. Additionally, the effect of polypropylene fibres as a spalling prevention technique is modelled via a modification of the intrinsic permeability …

Hillslope-scale soil moisture estimation with a physically-based ecohydrology model and L-band microwave remote sensing observations from space
Soil moisture is a critical hydrosphere state variable that links the global water, energy, and carbon cycles. Knowledge of soil moisture at scales of individual hillslopes (10's to 100's of meters) is critical to advancing applications such as landslide prediction, rainfall-runoff modeling, and …

Influence of near surface moisture gradients in concrete on 'Autoclam' permeation measurements
In this thesis the effect of moisture in the surface layers of concrete on the permeation properties measured using the 'Autoclam' is investigated. A literature survey indicated two main ways of removing the influence of moisture on these tests - to assess the moisture condition of the concrete and …

Understanding and predicting transient material behaviors associated with mechanical resonance in cementitious composites
… behaviors depended on the extent of damage and moisture states of a specimen. A small-scale disc vibration experiment was designed to enable imaging, using an environmental scanning electron microscope during vibration excitation in a controlled environment. Moisture migration within the paste …

Studies of moisture and alkalinity in self-levelling flooring compounds
… discussed has been the relation between the moisture in buildings and health. <p> Cementitious materials, when cast, contain excess water since this is necessary for workability and for flow properties. The pore solutions in cementitious materials, besides being high in water content, often …

Atmospheric controls on soil moisture-boundary layer interactions
… affects the interaction between the soil moisture state and the growth and development of the boundary layer (BL), leading to the triggering of convection. It is concluded that in mid-latitudes, for matters of convective triggering and response to land surface conditions, the critical …

Enhanced Soil Moisture and Streamflow Estimation in Ungauged or Data-Scarce Watersheds
… areas influence both the distributed (soil moisture state, runoff generation, or pollutant export) and integrated (streamflow) watershed responses. While streamflow is commonly used to constrain model parameters due to its availability and integrative nature, the issue of equifinality, where …

Processing and properties of recycled aggregate concrete
… approach (TSMA) and control of RAC initial moisture contents. By two-stage mixing approach, the compressive strength of RAC improved with different initial moisture states of recycled coarse aggregates. However, in case of shrinkage, some previous studies showed that RCA can absorb larger …

Biological growth on mineral façades
… in temperature gives high enough differences in moisture state to almost prevent microbial growth above the fasteners. As we know that organisms need a high relative humidity to grow, these results could explain the uneven distribution of biological growth on the façades with “white dots”. …
