Secondary emissions from alkali attack on adhesives and PVC floorings

Research output: Book/ReportReport

Abstract

The report describes three investigations of emissions from alkali attack on adhesives and floorings. The investigations show that low alkali levelling compounds, based on calcium aluminate cement, can act as a protection against secondary emissions of 1-butanol and 2-ethylhexanol, provided that the humidity does not exceed a critical level, which with some safety margin is recommended to be 90% RH. Five tested levelling compounds all had the same principal behaviour. A minimum thickness of the levelling compound is recommended to be 5 mm, although the investigations show that the levelling compounds also had protection capacity at 2 mm. One way of assuring that the humidity is below the critical level is to use self-desiccating concrete. A concrete with water-binder ratio of 0.43 together with a levelling compound proved effective.
