Analisis Karakteristik Beton Self Compacting Concrete Terhadap Penambahan Superplasticizer Master Gelenium ACE 8595
نویسندگان
چکیده
Beton Self Concrete Composite (SCC), memiliki sifat alir (flowable) sehingga dapat mengisi seluruh rongga beton tanpa melalui proses pemadatan dengan vibrator. Pemakaian SCC biasanya dilakukan pada struktur yang tulangan-tulangan rapat, dimana alat vibrator tidak digunakan untuk menggetarkan dan mengeluarkan udara terjebak didalam beton. Untuk mengetahui sejauh mana perilaku karakteristik menggunakan superplasticizer master glenium ACE 859 variasi dosis 0%, 1,1%, 1,3%, 1,5% dari berat semen. Penelitian mutu Fc’-60 MPa perencanaan metode SNI 03-6468-2000. Hasil penelitian terhadap segar didapat bahwa penambahan campuran dikategorikan sebagai Compacting slump tertinggi SP sebesar 700 mm. Kuat tekan maksimum diperoleh pemakaian 72,65 MPa. Nilai absorbsi umur 28 hari terjadi penurunan disetiap SP, 1,1% 0,76%, 1,3% 0,66%, 0,60%. kuat membuktikan 8595 meningkatkan rencana mengurangi penyerapan (absorpsi).

Properties of Self-compacting Concrete – an Overview
Self-compacting concrete can be defined as the concrete which requires no vibrations and can flow around obstructions, encloses the reinforcement and fills up the formwork completely under its self weight. Over the last ten years, significant amount of work has been carried out on self-compacting concrete all over the world. In countries like Japan, Sweden, Thailand, UK etc., the knowledge of S...
متن کاملUltra High Performance Self Compacting Concrete
Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...
متن کاملSelf-Compacting Concrete - Procedure for Mix Design
Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper...
