Abstract

Polyacrylamide (PAM) is one of the widely used flocculant of cement-based materials, and its degradation products are potentially toxic to the environment. However, few studies have explored the degradation and leakage behavior. Here, these experiments on the total organic carbon, 1H nuclear magnetic resonance, infrared spectroscopy, gel permeation chromatography and gas chromatography–mass spectrometry were carried out to insight into this behavior. The results show that the leakage ratio of PAM from cement paste decreases with the extension of cement hydration time. This flocculant exhibits degradation behavior, the molecular weight of leaked PAM decreases and its amide group and carboxyl group reduce with the prolongation of hydration time. The degradation products of PAM in cement after 70 d contain a variety of small molecular weight organic compounds, such as aldehydes, alcohols, phenols and esters. PAM can definitely degrade and leak from cement-based materials, and the degradation products may contain potentially toxic organics, thus the PAM potential environmental pollution cannot be ignored.
