PT. Freyssinet Total Technology merupakan perusahaan konstruksi internasional. Perusahaan ini cukup dipandang dalam produksi bahan konstruksi, salah satunya adalah beton. Bersama perusahaan ini, ITS menggelar kuliah tamu untuk menambah wawasan mahasiswa dalam mata kuliah teknologi bahan bangunan, struktur beton pratekan, dan teknologi beton pracetak. 
 
Dalam kuliah tamu tersebut, Lorenzo membahas lebih dalam mengenai produksi beton pratekan. Beton  yang lebih dikenal sebagai beton prategang itu adalah beton bertulang yang telah diberikan tegangan dalam untuk mengurangi tegangan tarik potensial. Beban tersebut diperoleh sebagai akibat pemberian beban yang bekerja. <\/p>\n

Dikatakannya, metodologi kerja dan peralatan adalah hal yang tak boleh lepas dari perhatian. Metodologi dan peralatan tersebut antara lain instalasi bekisting, penguatan bagian bawah dan instalasi saluran datar, instalasi strand,<\/em> serta dintalasi angkur.  <\/p>\n

Selanjutnya, perlu dilakukan perletakan profil kabel dan penguatan sisi bagian atas. Kemudian perlu diperhatikan pula inspeksi kekerasan, finishing, serta perawatan. "Poin kuncinya adalah menjaga keurutan," terang Lorenzo.<\/p>\n

Untuk penekanan sendiri dilakukan dengan prinsip dongkrak hidraulik. Terakhir, dilakukan grouting, yakni sebuah pekerjaan untuk mengisi celah atau rongga dalam sebuah struktur. "Kuncinya ada di penekanan kabel yang dilakukan tiga sampai empat hari dari pengecoran pelat," tutup pria asal Italia tersebut. (mbi\/ven)<\/p>\n","protected":false},"excerpt":{"rendered":"

Penggunaan beton pratekan di dunia industri teknik sipil terbilang menjanjikan. Hal ini disebabkan beton pratekan memiliki berbagai keunggulan dibandingkan beton bertulang biasa sehingga lebih menguntungkan dari segi kinerja, biaya, waktu, dan keselamatan. Kendati demikian, ada beberapa hal yang perlu diperhatikan dalam membuat beton pratekan. Hal ini dibahas tuntas oleh Lorenzo Marengo, kepala teknisi di Freyssinet, dalam kuliah tamu bertajuk Balok Prestressed Sistem Freyssinet, Rabu (8\/2).<\/p>\n","protected":false},"author":1,"featured_media":24947,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[14],"tags":[],"class_list":["post-24946","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-berita-utama"],"yoast_head":"\nProduksi Beton Pratekan, Ini Poin Kuncinya - ITS News<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.its.ac.id\/news\/produksi-beton-pratekan-ini-poin-kuncinya\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Produksi Beton Pratekan, Ini Poin Kuncinya - ITS News\" \/>\n<meta property=\"og:description\" content=\"Penggunaan beton pratekan di dunia industri teknik sipil terbilang menjanjikan.
