PENGARUH LIMBAH EGG TRAY DAN SEKAM BAKAR TERHADAP NILAI KUAT TEKAN BETON RINGAN
Abstract
Concrete is a mixture of cement, aggregate, water and certain additional ingredients. Making lightweight concrete
in principle requires cavities in the concrete. Another advantage of lightweight concrete, among others, is that it has a
good thermal resistance value, has a good sound resistance (silencer), is fire resistant. While the weakness of lightweight
concrete is the value of compressive strength is smaller than that of normal concrete so it is not recommended for
structural use. The purpose of this study was to determine the compressive strength of concrete using rice husk ash and
paper ash of egg shelves added to the manufacture of lightweight concrete
The method used in this study is an experimental study in the laboratory which includes material testing,
manufacture and testing of test objects. Test objects were made by 5 compositions with the percentage of rice husk ash
and egg rack paper by 10%, 25%, 55%, 80% and 95% of the weight of the cement while the compressive strength testing
was carried out at ages 7, 14 and 28 days.
The results of compressive strength testing showed that rice husk ash and paper ash of egg shelves could be used
as additive material for lightweight concrete for lightweight and non-structural concrete blocks. Addition of rice husk ash
and egg rack egg ash as much as 10% and 25% can be used as lightweight concrete material for light structures because
the compressive strength values are between 7-17 MPa and can be used for the walls to carry loads. Meanwhile, the
addition of rice husk ash and egg rack paper as much as 55%, 80% and 95% can be used for non-structural lightweight
concrete because it has compressive strength values between 3.5 - 7 MPa and can be used for separation walls or
isolation walls.
