Experimental study on effects of shape and content of fine particles on strength of calcareous mixed sand

Yantu gongcheng xuebao, 2023
In order to study the influences of different contents and shapes of fine particle on the mechanical properties of calcareous mixed sand, the angular quartz powder and round glass beads are used as the fine particle materials and mixed with the ...

Determination of the transitional fines content of sand-non plastic fines mixtures

Soils and Foundations, 2015
The transitional fines content is the boundary between fines-dominated and sand-dominated behaviour. Experimental and calculation methods for the determination of the transitional fines content of sand-non plastic fines mixtures are summarized based on former studies.

Influence of Fines Content and Particle Shape on Limiting Void Ratios of Sand Mixtures: DEM and AI Approaches

Buildings
The mechanical behavior of sand–fines mixtures is governed by their limiting void ratios, which are sensitive to fines content and particle morphology. Conventional empirical correlations often fail to generalize to a wide range of soils, limiting their ...

On the influence of the spatial distribution of fine content in the hydraulic conductivity of sand-clay mixtures

Earth Sciences Research Journal, 2018
Sand-clay mixtures are one of the most usual types of soils in geotechnical engineering. These soils present a hydraulic conductivity which highly depends on the fine content.

Effect of Fine Content on Liquefaction Resistance of Saturated Marine Sandy Soils Subjected to Cyclic Loading

Journal of Marine Science and Engineering
Offshore wind turbines are subjected to environmental loads such as wind and ocean waves throughout their entire service lives. Saturated sandy soils experience liquefaction under cyclic shear stresses induced by earthquakes or strong wave actions, which

Beneficial utilization of ultra-fine dredged sand from Yangtze River channel as a concrete material based on the minimum paste theory

Case Studies in Construction Materials, 2022
Ultra-fine sands are dredged periodically in order to maintain the normal activities of the Yangtze River Channel. Finding a new solution for managing these ultra-fine dredged sand becomes a challenge for channel managers.

Response of the fine root morphological and chemical traits of Tamarix chinensis to water and salt changes in coastal wetlands of the Yellow River Delta

Frontiers in Plant Science, 2022
To explore the adaptation of the fine root morphology and chemical characteristics of Tamarix chinensis to water–salt heterogeneity in the groundwater–soil system of a coastal wetland zone, T.
