Under the action of freeze–thaw cycles, the peak load 𝑁𝑢,𝑡Nu,t and initial elastic modulus 𝐸E of the composite column decreased, but the ductility coefficient 𝜇μ increased. Increasing the stirrup spacing could significantly improve the ductility of the composite column. After 100 ...
In order to study the strength properties of the weak soil reinforced by fibers, Kravchenko [18] conducted a series of unconsolidated undrained triaxial compression tests of fine-grained soil subjected to freeze–thaw cycles. Ahmadi studied the strength properties of natural and reinforced samples ...
The action of freeze–thaw (F–T) cycles of claystone exerts a profound impact on the slope stability of open-pit mines in water-rich regions. Microstructural changes are observed as a crucial factor in determining the hydraulic characteristics and mechanical behaviors of claystone. The present wor...
shotcrete; fracture toughness; freeze–thaw cycles; microstructure 1. Introduction Due to their excellent workability and mechanical performance, shotcrete materials have been applied as support measures in various engineering, such as tunnel engineering, slope engineering, dam engineering, etc. [1,2,3]...
Ultra-high performance concrete (UHPC) with excellent durability has broad application prospects in improving the durability of reinforced concrete (RC) structures. To clarify the influence of freeze–thaw cycles on the axial compression performance of U
Freeze–thaw cycles change the mechanical properties and structural characteristics of soils [3,4,5,6,7] and lead to soil deformation. A study on the physical properties of soils amid freeze–thaw cycles fundamentally emphasized the impact of two variables: the number of freeze–thaw cycles and...
waste tires; rubber fiber-reinforced soil; expansive soil; dynamic response; freeze–thaw cycles 1. Introduction Seasonally frozen soil is widely distributed all over the world, and the effect of freeze–thaw cycles on subgrades should not be neglected. Studies have shown that freeze–thaw cycles...
freeze–thaw cycles. The influence of various factors (freeze–thaw cycle number, replacement rate of recycled aggregates) on the compressive strength, quality loss rate, and rebound value of recycled concrete was analyzed. The results indicate that with the increase of freeze–thaw cycles and ...
The compression and splitting tensile strength decrease linearly with the increase in SFT cycles. Keywords: recycled brick aggregate; seawater and sea sand concrete; seawater freeze–thaw; strength; chemical crystallization 1. Introduction With the continuous development of urbanization worldwide, large-...
