The equivalent mortar volume method in the manufacturing of recycled aggregate concrete

Abstract

Many studies have observed that the mechanical properties of concrete made of recycled aggregate are worse than for concrete made of natural aggregate; this is mainly due to the mortar that is attached to the recycled aggregate. In literature, an equivalent mortar volume method in the manufacturing of recycled aggregate concrete has been proposed. This method treats the attached mortar as new mortar. The application of this method can reduce the use of natural materials while maintaining mechanical properties and eliminate the additional processes required for the production of recycled aggregates. The aim of this paper is to briefly describe the recent application of this method, present gaps in current research and anticipated directions for further research.

Streszczenie

Wiele badań wykazało, że właściwości mechaniczne betonu wykonanego z kruszywem pochodzącym z recyklingu są gorsze niż właściwości betonu wykonanego z kruszywa naturalnego, głównie ze względu na zaprawę zespoloną z kruszywem z recyklingu. W związku z tym w literaturze zaproponowano metodę równoważnej objętości zaprawy w wytwarzaniu betonu z kruszywem z recyklingu. Ta metoda traktuje dołączoną zaprawę jako nową zaprawę. Zastosowanie tej metody może zmniejszyć zużycie materiałów naturalnych przy jednoczesnym zachowaniu właściwości mechanicznych betonu i wyeliminować dodatkowe procesy wymagane do produkcji kruszyw z recyklingu. Celem tego artykułu jest krótki opis najnowszych zastosowań tej metody, przedstawienie luk w obecnych badaniach i przewidywanych kierunków dalszych badań.
