RESEAL Project. Topical Report on Laboratory Tests.

Abstract

This report summarises the activities carried out by CIEMAT (Programa de Caracterización

Hidrogeoquímica de Emplazamientos) and the results obtained during the RESEAL Project

concerning the Work Package 1: Laboratory experiments. The tests were focused mainly to

the investigation of the hydraulic and gas transport properties of the sealing material and of

its geomechanical properties. Most of the tests have been performed with Serrata clay, as the

decision of using FoCa clay was not taken until July 97, and most tests were already started.

Results of the tests being performed with FoCa clay are also presented. Both compacted

samples and pellets/powder mixtures have been used. Some work carried out in the

framework of the FEBEX Project that can be useful for the objectives of RESEAL is also

presented.
