Wavy mortar foundation cracking:Our photo at left and the photos shown above right illustrate open crack sin the concrete block foundation wall of three different older homs. These wavy mortar cracks were detected in a home's basement. The wavy mortar is not a shrinkage crack. The photos inclu...
However, the decrease in the groundwater level leads to an increase in the effective self-weight stress of the layer below the original water level, soil consolidation, ground settlement around the foundation pit, and uneven settlement, inclination, and cracking of underground pipelines and surface ...
generating stresses sufficient to reach the tension rupture criterion in olivine, leading to full cracking of olivine grains from which the mesh texture of serpentine veins originates (e.g.32). In addition, the exothermic nature of the serpentinization reaction enables to maintain relatively...
caused by seismic waves, high-speed vehicles and wind loads, has a significant impact on the engineering construction and the surrounding environment, such as reducing the soil strength and increasing the settlement of the foundation, which leads to the deformation and cracking of the superstructure....
The sucker rod is widely used in the oil extraction industries. The different grade sucker rod can be applied in different applications. ● Grade C sucker rod Moderate strength, has a certain degree of resistance to the sulfide stress cracking, it is suitable for sour environments. ● Grade D...
Engineering Models for Shear Crack Width and Shear Deflection in Slender Reinforced Concrete Beams Shear cracking in slender reinforced concrete beams with thin webs can result in significant shear crack width and deflection which is usually ignored in p... A Tiwari 被引量: 0发表: 2019年 roof sy...
With the continuous cracking of subsequent fractures, the induced stress superposition has more effect on the fracture propagation directions, which indicates that the stress interference becomes serious with the increase of fracture number. When fracture spacing increases to 85 m, the fracture ...
InSb crystal is an important Ⅲ-Ⅴ group semiconductor which has attracted much attention due to its diverse physical properties in past years. For example, it is always considered as a proper material for radiation detector manufacture, benefiting from its large atomic number, high density and the...
Exploring the feasibility and potential mechanism of synergistic enhancement of sludge dewaterability by ultrasonic cracking, chitosan re-flocculation and sludge-based biochar adsorption of water-holding substances 2022, Journal of Environmental Chemical Engineering Show abstract A novel conditioning approach for...
Failure Mechanism and Support Strategy of Deep Roadway193arc after the deformation. Bolt twisting, shedding, pallet damage, reinforced girder,steel mesh tearing, lining cracking happen. Roadway section is only 3.1*1.8m. Thereare no choices but to arrange the maintenance team to repair the roadway ...
