✦ Synopsis

A new method for ~nvestigating the evolution of the hardened cement paste structure is proposed, based on the application of radon as a radioactive indicator. The application of this Radiometric Emanation Method (REM) enabled us to follow continuously changes in the ceme~tpaste structure during setting and hardening at the required temperature and humidity. Comparison of the REM results withthose obtained by commonl) used methods showed that REM affords new insights into the evolution of the cement paste structure.

Changes in the surface area and microporosity of the cement paste samples can be advantageously investigated by REM.
