Abstract


Concrete production is identical to environmentally destructive starting from the
process of stone blasting, burning process and carbon emissions in the air. The production
of cement was declared as the world's second largest contributor of 7% of carbon
emissions in the world after the power plant is therefore needed innovation of
environmentally friendly concrete for the sustainability of infrastructure development
without damaging the environment. Glass powder and ash husk can be used as partial
substitution of cement as an alternative solution environmental problems. Both materials
are expected to function as filler because it has potential as pozzolan materials.
This study was conducted on the compressive strength and the properties of normal
concrete materials against the effect of using husk ash and glass powder on concrete
mixture at the Laboratory of Civil Engineering Department of Warmadewa University. The
test was performed on 7 days concrete with variation of the addition of husk ash and glass
powder by 5%, 10%, 15%, 20% and 25% by weight of cement
Replacement of husk ash and glass powder to the weight of cement affects the
compressive strength and specific gravity of the concrete. The strength of concrete with
glass powder showed to have a higher compressive strength when compared to the
compressive strength of husk ash ash. The maximum strength of concrete with glass
powder is obtained at 10% when the maximum strength of concrete with the husk ash was
added of 5%. In addition, on the specific gravity of concrete obtained the optimum value
when the addition of glass powder and concrete respectively by 20% and 5%.
Keyword: husk ash, glass powder, specific grafity of concrete, compressive strength of
