cracking behavior of polyacrylamide treated saline soil

Cracking Behavior of Polyacrylamide-Treated Saline Soil in

A quantitative analysis of crack patterns showed that thecross-points of the crack network and the crack length decreased as the PAM concentration increased.These results indicate that an increase in PAM reduces the shrinkage strain and the ?aws or poreswithin saline soils.

Experimental Investigation of the Compactability and Cracking

To improve the compaction properties of the saline-soil-based filling material that is used in highway subgrade and the cracking resistance capacity of a saline soil’s crust, the consistency limits, compactability, microstructure, and cracking morphology of untreated and PAM-treated saline soil were investigated.

Polyacrylamide degradation and its implications in - Nature

Polyacrylamide (PAM) is a water-soluble polymer with the ability to enhance a soil’s stability. PAM is currently being used to prevent irrigation-induced erosion and enhance the infiltration in farmland soil.

The saline soils were sampled from the soil crust and a depth of 2.0?3.0 m in Gansu Province, China. Two PAM concentrations (0.1% and 0.5% in mass ratio) were selected. The liquid limits and plastic limits of the saline soil samples from the surface (0?0.05 m) and a depth of 2.0?3.0 m noticeably increased as PAM concentration increased.

Effect of Anionic Polyacrylamide Polymer on Frost Heave

In the APAM polymer-free solution, the soil particles uniformly dispersed in the beaker (on a hot plate stirrer at room temperature), and a cloudy solution was then observed. However, in the APAM polymer solution (concentration of 0.25% and 3.00%), soil particles tended to aggregate, and the solution remained clear ( ).
