ABSTRACT
Nowadays, the activity of people getting higher, therefore the need of high quality in the
Construction. is the main purpose of government in terms of developing Construction.
One of the materials that can be used as material replacement is recycled aggregate. In
terms of this research, the scope of study is about comparison between recycle coarse
aggregate and natural aggregate in terms of specific gravity, apparent specific gravity,
absorption, los Angeles. Moreover, this research will also focus on the comparison
between recycled aggregate for 0%, 35%, 50% and 65% replacement.
This research was conducted with experimental research with the mixture of recycled
coarse aggregate for 0%, 35%, 50% and 65% replacement. Based on the result of
research, it is obtained that recycled aggregate has lower value than natural aggregate in
term of specific gravity, apparent specific gravity; while recycled aggregate has higher
value of absorption and los Angeles than natural aggregate. Moreover, the value of
compressive strength, flexural strength and modulus elasticity of 0% recycled aggregate
was the highest compared to 35%, 50% and 65% replacement. Finally, it can be
concluded that the percentage of recycled aggregate will influence the value of
compressive strength, modulus elasticity and flexural strength; and the 20 mm of size
recycled aggregate will also has the the high value of compressive strength, modulus
elasticity and flexural strength.
Key Word: Recycled Aggregate, Compressive Strength, Flexural Strength, and Modulus
Elasticity.

ABSTRAK
Saat ini, aktivitas masyarakat semakin tinggi, sehingga kebutuhan berkualitas tinggi
dalam Konstruksi tersebut. adalah tujuan utama pemerintah dalam hal mengembangkan
Konstruksi. Salah satu bahan yang dapat digunakan sebagai pengganti bahan daur ulang
agregat. Dalam hal penelitian ini, ruang lingkup studi tentang perbandingan antara
agregat kasar daur ulang dan agregat alami dalam hal berat jenis, jelas berat jenis,
penyerapan, los Angeles. Selain itu, penelitian ini juga akan fokus pada perbandingan
antara agregat daur ulang untuk 0%, 35%, 50% dan 65% pengganti.
Penelitian ini dilakukan dengan penelitian eksperimental dengan campuran agregat
kasar daur ulang untuk 0%, 35%, 50% dan 65% pengganti. Berdasarkan hasil penelitian,
diperoleh bahwa agregat daur ulang memiliki nilai lebih rendah dari agregat alam dalam
hal berat jenis, jelas berat jenis; sedangkan agregat daur ulang memiliki nilai yang lebih
tinggi dari penyerapan dan los Angeles dari agregat alam. Selain itu, nilai kuat tekan,
kuat lentur dan modulus elastisitas 0% agregat daur ulang adalah yang tertinggi
dibandingkan dengan 35%, 50% dan 65% pengganti. Akhirnya, dapat disimpulkan
bahwa persentase agregat daur ulang akan mempengaruhi nilai kuat tekan, modulus
elastisitas dan kekuatan lentur; dan 20 mm dari ukuran daur ulang agregat juga akan
memiliki nilai yang tinggi kuat tekan, modulus elastisitas dan kekuatan lentur.
Kata Kunci: Daur Ulang Agregat, Kuat Tekan, Kekuatan lentur, dan Modulus
Elastisitas.
