Concrete structures such as rigid pavements, tunnels, and runways at airports are usually subject to fatigue traffic loading during their service life. Research on the aftereffects of drying–wetting cycles coupled with alternating loads concrete erosion in saline–alkali coastal areas is considerable practical importance. For this study, we utilized specimens dimensions 100 mm × 400 strength rat...

• Clay swelling damage is an important weathering mechanisms affecting building stones. Wetting/drying cycles result in swelling/shrinkage of clays and crack development. The different models proposed to explain clay are reviewed. Traditional conservation treatments generally fail stop or mitigate damage. Promising methods inhibitors bacterial mineralization. Significant progress the understand...

The impact of heat treatment and wetting–drying cycles on the wetting properties sandy forest soils was explored. Topsoil upper subsoil were sampled at three beech sites in northern Germany. air-dried treated 20, 40 80°C for 24 h, with materials 20°C serving as reference. After wetting, or shock-frozen liquid N2 freeze-dried. Interfacial monitored by sessile drop contact angles (CAs) X-ray phot...

Moisture sorption can significantly influence hydrothermal ageing and alter the chemical rheological properties of bituminous mastics. Mineral filler particles are added to binders form mastics with increased stiffness. The addition fillers considerably change moisture physico-chemical by surface interactions physical presence. This study aims investigate effect type on moisture-induced changes...

Motivated by the puzzle of sorption hysteresis in Portland cement concrete or cement paste, we develop in Part II of this study a general theory of vapor sorption and desorption from nanoporous solids, which attributes hysteresis to hindered molecular condensation with attractive lateral interactions. The classical mean-field theory of van der Waals is applied to predict the dependence of hyste...

The long-term benefit brought in lime-treated soil can be altered by the nature of surrounding wetting fluid, thus, affecting its durability. However, studies regarding such impact are limited. In this study, influence different fluids on microstructural, physicochemical modifications, and Unconfined Compressive Strength (UCS) evolution is investigated. Lime-treated soils subjected to drying cy...
