Effect of drying-wetting cycles on the durability of calcareous sand reinforced by MICP and recycled shredded coconut coir (RSC)

open access: yesBiogeotechnics, 2023
Microbial-induced carbonate precipitation (MICP) technique has been adopted in geotechnical engineering widely. In this study, the effect of drying-wetting cycles on MICP-recycled shredded coconut coir (RSC) reinforced calcareous sand was studied, and ...

Prebiotic condensation through wet–dry cycling regulated by deliquescence [PDF]

open access: yesNature Communications, 2019
AbstractWet–dry cycling is widely regarded as a means of driving condensation reactions under prebiotic conditions to generate mixtures of prospective biopolymers. A criticism of this model is its reliance on unpredictable rehydration events, like rainstorms. Here, we report the ability of deliquescent minerals to mediate the oligomerization of glycine

Wet–dry cycles impact DOM retention in subsurface soils [PDF]

open access: yesBiogeosciences, 2018
Abstract. Transport and reactivity of carbon in the critical zone are highly controlled by reactions of dissolved organic matter (DOM) with subsurface soils, including adsorption, transformation and exchange. These reactions are dependent on frequent wet–dry cycles common to the unsaturated zone, particularly in semi-arid regions. To test for an effect

EFFECT OF WETTING AND DRYING CYCLES ON ADDED POTASSIUM RELEASE TO SOME CALCAREOUS SOILS IN NORTH IRAQ [PDF]

open access: yesMesopotamia Journal of Agriculture, 2010
Two surfaces soils horizon from calcareous soils in Mosul city classified as calciorthid with semictite dominance were chosen to study the effect of wetting and drying cycles on release of native and added potassium.Potassium was added to soil samples at

Chloride Ion Penetration into Cracked UHPFRC During Wetting-drying Cycles

open access: yes, 2021
The subject of this paper is the extent to which, during wetting–drying cycles, chloride ions can penetrate Ultra-high-Performance Fibre Reinforced Cementitious Composites (UHPFRC) specimens subjected to combined mechanical and environmental load. Pre-cracking was obtained by subjecting prismatic specimens (40 × 40 × 60mm3) to four-point bending until ...

Experimental Study on Dynamic Compression Characteristics of Red Sandstone under Wetting-Drying Cycles

open access: yesAdvances in Civil Engineering, 2020
To study the influence of wetting-drying cycles on dynamic mechanical properties of rock masses, the impact compression tests of red sandstone samples were carried out by using a split Hopkinson pressure bar (SHPB) apparatus with a diameter of 50 mm. The

Shear Strength Deterioration of Compacted Residual Soils under a Wind Turbine due to Drying-Wetting Cycles and Vibrations

open access: yesAdvances in Civil Engineering, 2021
The soil beneath a wind turbine withstands not only environmental impacts but also continuous vibrations transmitted from the superstructure. This paper presents an experimental study of the deterioration characteristics of shear strengths of residual ...
