Cracking Tendency

The utilization of crumb rubber particles extracted from waste tires in the production of self-compacting concrete (SCC) is a decent and sustainable solution to mitigate the impacts of such waste on environment. The aim of this study is to evaluate the cracking tendency of SCC with different content of crumb rubber extracted from waste tires. Five SCC mixtures were prepared. The reference mix was made with natural sand while the other four mixes were made with crumb rubber in which the natural sand was volumetrically replaced by crumb rubber at ratios of 10 %, 20 %, 30 % and 40 %, respectively. The results show that the addition of crumb rubber delays the cracking of concrete. The cracking time increases with the increase of the rubber content. The results also reveal that the addition of rubber particles not only increases the cracking time but also reduces the initial and final crack width.

Self Compacting Concrete

Dalam abu vulkanik dan semen unsur kimia yang paling utama adalah silica.  Dibeberapa negara abu vulkanik sering dijadikan bahan campuran untuk membuat semen dan material beton.  Beton banyak dipakai sebagai bahan bangunan, namun dalam proses pengecoran sering mengalami kendala dikarenakan jarak tulangan yang terlalu rapat.  Salah satu perkembangan teknologi beton adalah beton Self Compacting Concrete (beton SCC).Tulisan ini membahas pemanfaatan abu vulkanik untuk aplikasi beton SCC. Uji eksperimental dilakukan untuk mengetahui pengaruh abu vulkanik di beton SCC, yang digunakan dengan penambahan dan penggantian parsial mulai dari 0% sampai dengan 10% berdasarkan berat bahan semen. Pengujian kuat tekan dilakukan dengan menggunakan tiga spesimen silinder standar untuk setiap data. Hasil pengujian menunjukkan bahwa abu vulkanik dapat memperbaiki kuat tekan beton SCC dengan metode penambahan dan penggantian semen dengan dosis optimum 5% berat semen.Kata kunci : abu vulkanik, semen, material beton dan beton SCC
