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.

Does anionic polyacrylamide affect early properties of cement?

In this paper, the effects of anionic polyacrylamide (A-PAM) with different mass ratios on the early properties of cement, including hydration, structural build-up, setting time and early strength development were studied. The interaction between A-PAM and cement particles was also investigated.

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.

How is anionic polyacrylamide synthesized?

Synthesis mechanism The anionic polyacrylamide was synthesized by copolymerizing AM and SAS monomers. The essence of copolymerization is the free radical reaction. Thus, this chain reaction can be divided into three distinct processes: initiation, propagation, and termination.

Is Apam-t a novel anionic polyacrylamide?

Conclusion APAM-T is a novel anionic polyacrylamide which has been successfully synthesized by ultrasonic initiated template copolymerization. Characterization results showed the evidence of the microblock structure’s existence and the enhancement of copolymerization degree by adding the template.

Can polyacrylamide improve the durability of s-WRF?

This is hopeful to provide new ideas for enhancing the durability of S-WRF. Polyacrylamide (PAM) is a kind of commercial viscosity amendment organic polymer, which can improve the mechanical properties and durability of cement-based materials , , , .
