—The building construction is considered one of the
largest consumers of natural raw materials and the production
of iron generates about 0.75 t of slag per ton of pig iron
produced. It is known that the natural resources are finite and
the Brazilian National Policy on Solid Waste, becomes
mandatory to give a destination for solid waste than to dispose
them in landfill sites. This research was proposed to study the
use of silicon slag to replace natural sand in mortars. The
mortars were produced with 0%, 25%, 50%, 75% and 100% of
replacement of the natural sand to silicon slag, by mass. The
tests were consistency, compressive and flexural strength,
capillary water absorption, and air permeability. The mortars
with silicon slag had good results and showed that it can replace
natural sand in mortars.
