Earthen plasters, as representative elements of traditional built heritage, are increasingly reconsidered within contemporary conservation strategies addressing climate challenges and sustainable design, due to their low environmental impact and favourable hygrothermal performance. Although numerous studies have explored different formulations, however, long-term behaviour remains scarcely investigated. This study evaluates the time-dependent physical and mechanical behaviour of earthen plasters modified with sisal fibres and marble dust, subjected to accelerated ageing within the ITER project. Results show no significant degradation in shrinkage, bulk density, compressive and flexural strength, while surface hardness is affected without compromising overall performance.
