Can anionic polyacrylamide improve climatic durability of solidified waste rock fine?

In order to improve the climatic durability of solidified waste rock fine (WRF), anionic polyacrylamide (APAM) was innovatively introduced to amend solidified WRF in this study. The effects of APAM content, freeze-thaw (F-T), and wet-dry (W-D) cycles on the mechanical behaviors of solidified WRF were explored.

What is ionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.

How dangerous is polyacrylamide (PAM)?

4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.

Does anionic polyacrylamide influence hydration and structure formation?

It is reported that anionic polyacrylamide (APAM) is able to influence the hydration, structure formation, setting time, and early strength development of stabilized matrix.

Is polyacrylamide an organic nitrogen source for soil microorganisms?

Kay-Shoemake, Jeanine L., Mary E. Watwood, Rodrick D. Lentz, and Robert E. Sojka. 1998. “Polyacrylamide as an Organic Nitrogen Source for Soil Microorganisms with Potential Effects on Inorganic Soil Nitrogen in Agricultural Soil.”

Does polyacrylamide reduce sediment in irrigation?

PAM, used following NRCS guidelines (Interim conservation practice standard—irrigation erosion control (polyacrylamide), 1995, Anionic polyacrylamide (PAM) erosion control (Acre)‐code 450 USDA‐NRCS, NHCP, 2001), reduced sediment in runoff 94% in 3 years of furrow irrigation studies in Idaho (Lentz and Sojka, 1994).
