Liquid Chromatography and Mass-Spectrometry Analysis of Transformation Products of Plasticizers and Antifreezing Agents for Concrete Formed during its Use

摘要

The present study considers the transformation products of a number of compounds, including ones used as plasticizers and antifreezing agents for concrete, which can liberate ammonia during exploitation of the concrete products. We have analyzed plasticizers, antifreezing agents, and products of their transformation that are leached by water and/or organic solvents. The analysis procedure has been used for analysis of concrete samples from a real construction site.
