Gambar 2. Hubungan Pesentase Limbah Beton dan Kuat Tarik Belah Beton dengan fas = 0,45,
umur beton 28 hari
Berdasarkan Gambar 2 di atas, penambahan persentase limbah beton sebesar 15 %, dapat
mencapai kuat tarik belah beton sebesar 4,003 MPa, seiring dengan bertambah besarnya
penambahan persentase limbah beton, kuat tarik belah beton mengalami penurunan.
