Rheology Properties of Underwater Cement Paste with Nonionic Polyacrylamide | Iranian Journal of Science and Technology, Transactions

Abstract In this article, underwater cement paste (UWP) was fabricated through using the high molecular nonionic polyacrylamide (PAM) as anti-washout admixtures (AWAs). The traditional coaxial rotary method was used to systematically investigate UWPs rheology parameters.

Molecular Dynamics-Assisted Design of High Temperature-Resistant Polyacrylamide/Poloxamer Interpenetrating Network Hydrogels - PMC

Due to its excellent properties such as flocculation, thickening, resistance reduction, and dispersion, PAM with high molecular weight can increase the viscosity of oil field injection fluid and improve the heterogeneity of reservoirs, so it is widely used as an oil displacement agent in the process of oil recovery [ 5, 6, 7 ].

The Thermal Gelation Behavior and Performance Evaluation of High Molecular Weight Nonionic Polyacrylamide and Polyethyleneimine Mixtures for In

It is well known that the gelling solution prepared with high molecular weight PAM possesses high initial viscosity. This would make it difficult on the injection process for water shutoff treatment. Fortunately, gel systems prepared with nonionic polyacrylamide (NPAM) were studied.

Molecular dynamics simulation of self-assembly and viscosity behavior of PAM and CTAC in salt-added solutions

To study the rheology properties and microstructures of the CTAC and PAM, we test the viscosity of CTAC/NaSal solution, PAM solution, and CTAC/PAM/NaSal solution using RNEMD simulation, respectively. The curves in Fig. 10 exhibit a similar tendency: the viscosities show a distinct shear-thinning behavior when the shear rate increases, which agree with the experiment [ 58 , 59 ].

Polyacrylamide in Agriculture and Environmental Land Management

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation©induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms

Home - Springer - Effect of super water absorbing polymer based anti-washout admixtures on the properties of seawater-mixed cement paste

This paper studies the mechanism of anti-washout performance of hydroxypropyl methylcellulose (HPMC) and polyacrylamide (PAM) in seawater-mixed cement paste. Using seawater as concrete mixing water can reduce the consumption of freshwater resources. The ionic environment of seawater can promote hydrogen bonds formation of HPMC, and PAM. The viscosity of the solution increased with the numbers
