Pemanfaatan Limbah Sayur Sebagai Agen Dalam Pembuatan Beton Pulih Mandiri
No full textBeton merupakan bahan kontruksi yang terdiri dari campuran material seperti semen, agregat dan air serta bahan tambahan lainnya (additive). Saat ini penggunaan beton semakain meningkat karena beton merupakan bahan kontruksi yang memiliki beberapa kelebihan, seperti mudah dalam proses pengerjaannya dan harga material penyusunnya relatif murah serta mudah didapatkan. Tujuan penelitian ini untuk mengetahui perubahan pada fisik beton menggunakan campuran ekstrak limbah sayuran dan menganalisa pengaruh faktor nilai slump 10-30 terhadap nilai kuat tekan beton pada mutu beton self healing dengan metode yang digunakan untuk menghitung campuran beton (Mix Design) berdasarkan SNI 03-2834-2000. Hasil nilai slump pada penelitian self healing concrete dengan nilai slump 10-30 mm pada beton varian ekstrak limbah sayuran 0% dan 3% memenuhi standar yaitu 20mm dan 30mm. Sedangkan pada varian 5%, 7% dan 9% tidak memenuhi standar yaitu 140mm, 220mm dan 200mm. Hasil kuat tekan beton pada perendaman umur 28 hari pada pengadukan pertama dengan varian 0%, 3%, 5%, 7% dan 9% mengalami penurunan berturut-turut dari 37,40 Mpa, 28,76 Mpa, 25,01 Mpa, 20,30 Mpa, dan 20,14 Mpa. Untuk pengadukan kedua pada varian 0%, 3% dan 5% mengalami penurunan dari varian 0% yaitu 37,40 Mpa, 29,15 Mpa dan 22,15 Mpa, sedangkan varian 7% mengalami kenaikan yaitu 23,26 Mpa dan varian 9% mengalami penurunan yaitu 18,79 Mpa. Penglihatan secara visual pada beton yang diretakkan pada varian 3% dan 5% mengalami pemulihan di hari ke 14 dan hari ke 21, tetapi tidak dapat memulihkan retakan sepenuhnya pada beton. Sedangkan pada varian 7% dan 9% dapat memulihkan di hari ke 14 dan hari ke 10 hampir pulih sepenuhnya
