Soil compaction as the possible cause of wilting and premature ripening of sunflower - Short Communication

open access: yesPlant Protection Science, 2006
Brown patches of the size from several square metres to hectares or individual dying plants appeared in otherwise green stands. Affected plants wilt and ripen sooner than healthy ones, causing them to have smaller seeds or none at all in the central part

The plastic limit of clays [PDF]

open access: yes, 2013
The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Reducing Compressibility of the Expansive Soil by Microbiological-Induced Calcium Carbonate Precipitation

open access: yesAdvances in Civil Engineering, 2021
Most of the research studies on the improvement of expansive soils are focused on reducing their expansive properties; however, there are few studies on the impact of the soil compressibility after the improvement.

Compression behaviour of hydrate bearing carbonate sand - fines mixtures [PDF]

open access: yesE3S Web of Conferences, 2020
High gas hydrate content has been found in fine-grained sediments containing substantial amount of foraminifera in the South China sea. One of the possible hydrate accumulation habits is filling the intra- particle voids in the foraminifera.

Effect of Height-to-Diameter Ratio on the Compression Test Results of Remodeled Loess and Its Mechanism

open access: yesBuildings, 2023
The confined compression test is the most widely used test to study the compressive deformation of soil in a laboratory, and the height–diameter (H/D) ratio has a significant effect on the confined compression test results.

Improvement of a subgrade soil by using EarthZyme and cement kiln dust waste [PDF]

open access: yesArchives of Civil Engineering, 2021
Soil stabilization techniques are widely used for road construction to improve the properties of the subgrade materials. Using new additives and stabilizers to improve soil properties can reduce the costs of construction and reduce the possible negative ...

Anisotropic creep model for soft soils [PDF]

open access: yes, 2008
In this paper a new anisotropic model for time-dependent behaviour of soft soils is presented. The formulation is based on a previously developed isotropic creep model, assuming rotated Modified Cam Clay ellipses as contours of volumetric creep strain ...

Compression law of soils

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1987
ABSTRACT A formulation for the compression of sedimentary soils was attempted by separating the compression type into the rapid process of upper sediments and slow process of subsoils, based on both the experimental results and theoretical consideration.

DYNAMIC OF PRESSURE-DEFORMATION CURVE IN UNIAXIAL COMPRESSION TEST IN DIFFERENT LOAD TIMES [PDF]

open access: yesEngenharia Agrícola, 2017
: The loading application time by machinery tires and agricultural tires is one of the factors of soil compaction. We evaluated the effect of loading reduction time in uniaxial compression test, in laboratory, in some physical and mechanical parameters ...
