KARAKTERISTIK BETON BUSA MENGGUNAKAN ABU CANGKANG KERANG HIJAU SEBAGAI BAHAN PENGANTI SEMEN PORTLAND
Keywords:
beton busa, cangkang kerang hijau, kuat lenturAbstract
Dengan semakin meningkatnya kepedulian terhadap masalah lingkungan, pengembangan bahan beton diupayakan berasal dari limbah atau bahan organik. Dalam penelitian ini, cangkang kerang hijau digunakan sebagai bahan penganti semen dengan kadar yang digunakan sebesar 0%, 5%, 7,5% dan 10% dari berat total semen. Ruang lingkup penelitian ini termasuk mengetahui sifat fisik dan mekanik dari beton busa yang meliputi berat jenis beton busa, kuat tekan dan kuat lentur. Dari hasil penelitian didapatkan bahwa berat jenis beton busa sebesar 604 kg/m3 sampai 697 kg/m3. Kuat tekan pada umur 28 hari sebesar 1.4 MPa – 1.6 MPa. Sedangkan kuat lenturnya sebesar 0.85 MPa – 0.95 MPa.Downloads
