Review of the mechanical properties of concrete by adding clay brick residues as a partial substitute for coarse sand

SUMMARY

In the world of construction, the amount of clay brick waste (CCB) from demolition and construction is increasing considerably, and such waste is reused to mitigate environmental pollution. The present research aimed to make a systematic literature review on the mechanical properties of concrete by adding CCB as a partial substitute for coarse sand, whose methodology was to review 80 papers indexed in database such as Scopus, Ebsco Host, Scielo comprised between the years 2017 to 2021. As results were found that the mechanical properties of concrete improve by adding brick waste, process in which the CCB are crushed with the Angels abrasion machine, the sand samples were partially replaced in 15%, 20% and 25% of the CCB as partial substitute of the sand the results of this addition showed that when the addition is respected a good compressive strength is obtained, but when it exceeds 30% would cause a low density due to high absorption of the CCB. It is concluded that the replacement of CCB by sand can be used in the production of concrete because it improves its mechanical properties in addition to protecting the environment.
