Abstract
Abstract. Egypt's agricultural waste production has increased significantly in recent decades,
leading to improper disposal methods and environmental pollution. Rice husks are the most
common agricultural solid waste in Egypt, contributing to "black clouds" and causing health issues.
On the other hand, Cement, a crucial component of construction materials, generates unsound
residues and greenhouse gas emissions. Green concrete with rice husks could be a profitable
solution for environmentally sound construction, reducing cement consumption and increasing the
durability and integrity of new materials. This study investigates the use untreated rice husk fibres
with a concrete mixture, avoiding burning and contributing to environmental pollution.
Experimental work involved partial substitution of cement with rice husks in 4%, 6%, and 8%. The
results showed that partially replacing cement with 4% untreated rice husk preserved reasonable
compressive strength of 16.11 MP, improved thermal insulation by reducing thermal conductivity
by 2.69%, and lowered production costs by 2.25%.
