Effect of Dry‐Wet Cycling on the Mechanical Properties of High‐Water Materials [PDF]

Advances in Civil Engineering, 2020
As a new grouting reinforcement material, high‐water materials (HWMs) are being increasingly applied in different fields. This means that the environment in which these HWMs are employed are varied and increasingly complex. The dehydrating and saturation cycle of HWM caused by changes in the environment is referred to as the dry‐wet cycle.

Effect of Dry‐Wet Cycles and Freeze‐Thaw Cycles on the Antierosion Ability of Fiber‐Reinforced Loess [PDF]

Advances in Materials Science and Engineering, 2021
Compared with plain soil, polypropylene (PP) fiber‐reinforced soil has markedly improved mechanical properties and can be used in slope protection projects. To investigate the reduction law of the antierosion ability parameters of PP fiber‐reinforced loess under dry‐wet (D‐W) cycles and freeze‐thaw (F‐T) cycles, we took loess from Yan’an, China, mixed ...

Drying-Wetting Cycles: Effect on Deep Soil Carbon [PDF]

Soil Systems, 2018
In the Southeast United States (U.S.), the climate is predicted to be warmer and have more severe drought in the summer. Decreasing rainfall in summer months should create more severe soil drying, which will eventually affect re-wetting cycles deeper in the soil profile.

Concrete shrinkage and creep under drying/wetting cycles

Cement and Concrete Research, 2021
Abstract Concrete shrinkage and creep under variable hydric conditions are important factors for the safety and durability of concrete especially in nuclear reactor or nuclear waste storage background. A large (and long – more than 900 days) experimental campaign, conducted on two different concretes, has therefore been designed to study the strains ...

Study on the Deterioration of Concrete under Dry–Wet Cycle and Sulfate Attack [PDF]

Materials, 2020
In order to study the deterioration and mechanism of dry–wet cycles and sulfate attack on the performance of concrete in seaside and saline areas, the deterioration of compressive strength of concrete with different water cement ratios under different erosion environments (sodium sulfate soaking at room temperature and coupling of dry–wet cycling and ...

Pengaruh Drying dan Wetting Cycle Terhadap Kuat Geser Tanah Lempung

, 2022
 The landslide that occurred in Pagar Alam City was caused by high rainfall and the dry wet cycle was also one of the causes of the weakening of the mechanical properties of clay soil in the area, causing avalanches.

The Uniaxial Creep Characteristics of Red Sandstone under Dry‐Wet Cycles [PDF]

Advances in Civil Engineering, 2020
Water is one of the most important factors that affect the long‐term stability of geotechnical engineering structures. Rainfall often results in periodic changes in the water content in underground rock, which is subjected to alternating dry‐wet cycles. In this paper, in order to study the short‐term and long‐term mechanical properties of red sandstone
