Abstract: Abstract In water-saturated karst environments, existing shield tunnels are under external water pressure, posing potential water inrush hazards. It is an effective method to improve the permeability of the strata near the ...

Abstract: AbstractA retarder is often required to maintain the workability of sulfoaluminate cement-based grouting materials (SCGMs). Carbohydrates are widely used as cement retarders, but a high carbohydrate content can degrade the ...

Abstract: AbstractOutdoor microclimate is critical in assessing thermal comfort and building energy efficiency. However, traditional numerical simulations are limited by low computational efficiency due to their large model scales ...

Abstract: Concussion, or mild traumatic brain injury (mTBI), is frequently associated with sports activities. It has generally been accepted that neck strengthening exercises are effective as a preventive strategy for reducing ...

Abstract: revious studies documented that a distinct southward shift of central Pacific low-level wind anomalies occurring during the ENSO decaying phase is caused by an interaction between the western Pacific annual cycle and El ...

Abstract: AbstractSulfoaluminate cement–based grouting materials (SAGMs) are frequently employed in projects concerning reinforcement and repair. Retarders are often added to SAGMs to improve their workability by delaying the hydration ...
