ANALISIS KUAT TEKAN BETON MENGGUNAKAN LIMBAH KERAMIK SEBAGAI PENGGANTI SEBAGIAN AGREGAT KASAR

Abstract

n construction work, it is often found that unused building materials / materials are disposed of as waste.
If the waste is disposed of carelessly, it can cause new problems in the environment. Ceramic shard waste is an
example of a ceramic factory or building construction work. If you can process it creatively, it will produce a
more useful product. The purpose of this study was to analyze the comparison of the results of the compressive
strength of concrete in normal concrete and concrete using ceramic waste. The author conducted this research
by comparing the results of the Slump Test and the results of the compressive strength of normal quality fc 25
concrete with fc 25 concrete which has been added with ceramic waste as much as 20% and 40%. The test object
used in this study is a cylinder with a size of Ø15 cm x 30 cm, for each experiment as many as 6 specimens, with
a compressive strength test carried out at the age of 7,14,28 days after first curring. From the results of this study,
the slump value of fc 25 Normal Concrete and fc 25 Concrete with added ceramic waste material meets the
standard of slump target 7.5 cm to 15 cm, for plates, beams, columns and walls according to SNI 03-2834- 1992),
and from the results of the compressive strength of fc 25 concrete with the use of ceramic waste by 20%, the
compressive strength of concrete is 21.36 MPa and the use of ceramic waste is 40%, the compressive strength of
concrete is 17.68 MPa which is smaller than the compressive strength. Normal concrete fc 25 is 27.19 Mpa. From
the results of the concrete compressive strength, it can be seen that there is a decrease in the compressive strength
of the concrete due to an increase in the percentage of ceramic waste. So that it can be concluded that the use of
ceramic shard waste composition is not recommended for building construction structures
