Abstract

Environmental and sustainability issues have transpired as a result of the fast population increase, ascending construction and demolition activities, so there is a need for new materials and construction waste management. This study investigates the use of nanosilica extracted from rice husk ash and recycled aggregates (RA) extracted from demolition sites. RA mechanical qualities were assessed, and nanosilica made from rice husk ash was added to concrete with different nanosilica dosages (0.4%, 0.8%, and 1.2%) along with 50% and 100% recycled aggregate substitutions. Tests of compressive strength revealed that nanosilica greatly increased the strength, validating RA as a workable and sustainable substitute material. Rice husk can also be a precursor for nanosilica production, promoting reuse and sustainability in construction.
