  • Early age properties of hydraulic lime mortar prepared using heavy metal contaminated aggregate [Elektronski vir]
    Turk, Tilen, magister inženir kemijskega inženirstva ...
    Traditional stone aggregates used to prepare mortars are generally considered inert fillers that do not interact with a binder. The European Green Deal, on the other hand, encourages the use of ... secondary material as aggregate. This secondary material is rarely an inert part of lime-based composites. This study focuses on heavy metal contaminated aggregate, for which has already been confirmed to alter microstructure development and lower the early strength of cement composites. Its influence on the early age properties of hydraulic lime mortar was studied through microstructure development recorded using transmission ultrasound technique and tensile and compressive strength after 1, 3 and 7 days. Results are then compared to those of cement composites. The obtained results show that heavy metals delay microstructure development of hydraulic lime mixture during the first 60 hours, but do not decrease the tensile and compressive strength of the mortar after 3 and 7 days, as is the case with cement mortar.
