Abstract

Self Compacting Concrete (SCC) is concrete with high fluidity so that it can flow and fill the spaces in the mold without the compaction process. This study discusses the effect of the adding of kaolin and polypropylene fibers in order to increase the flowability, compressive strength, flexural strength, and tensile strength in self-compacting concrete. The additional material of kaolin was 5%, 10%, and 15% of the cement weight. The polypropylene fibers were 1%, 1.5%, and 2%. The flowability test, which was used, was Table flow, V-Funnel, and L-Box. Compressive strength testing was conducted when the concrete was 7, 14, and 28 days old. The flexural test was performed with a measurement of 150 x 150 x 600 mm as many as 18 specimens tested at the age of 28 days. The results showed that the addition of kaolin and polypropylene fibers met the flowability specifications of self-compacting concrete. The addition of polypropylene can increase the flexural strength and tensile strength of the concrete beam, but cannot increase the compressive strength of self-compacting concrete.

Abstract

Beton mutu tinggi merupakan beton dengan perlakuan khusus yang tidak dapat selalu dicapai hanya dengan penggunaan material konvensional tanpa penambahan bahan tambah khusus. Beton mutu tinggi memerlukan penggunaan semen yang lebih banyak dari pada penggunaan semen pada beton normal maka perlu ditambahkan fly ash pada campuran beton mutu tinggi untuk mengurangi penggunaan semen walaupun tidak terlalu signifikan. Tujuan dalam penelitian ini untuk mengetahui berapa jumlah proporsi yang sesuai dalam penambahan zat additive (bestmittel) dan fly ash pada beton mutu tinggi serta untuk mengetahui pengaruh penambahan zat additive (bestmittel) dan fly ash terhadap kuat tekan beton mutu tinggi. Pembuatan benda uji menggunakan silinder berukuran diameter 15cm dan tinggi 30 cm dengan 3 variasi, dan diuji pada umur 28 hari. Penambahan zat additive (bestmittel) pada beton mutu tinggi berbahan dasar fly ash mempengaruhi kuat tekan beton. Semakin besar fly ash yang digunakan maka semakin besar nilai kuat tekan, tetapi akan menurun kuat tekannya jika terlalu banyak penggunaan fly ash yang ditujukan sebagai pengganti sebagian semen. Hasil kuat tekan beton dengan penambahan fly ash dan zat additive (Betsmittel) 5%; 7,5%; dan 10% sebesar 35,95 MPa; 41,49 MPa; dan 40,45 Mpa.

Abstract

This study evaluated the seismic performance of flat slab structures designed according to four international standards: SNI 2847-2019 (Indonesia), NZS 3101:2006 (New Zealand), IS 456-2000 (India), and JSCE 15-2007 (Japan). A five-story reinforced concrete building was modeled using ETABS for nonlinear pushover analysis, while MATLAB was utilized for calculating slab thickness, moment distribution, reinforcement design, and punching shear strength. Results unveiled that the JSCE 15-2007 code provided the stiffest system with minimal lateral displacement and the highest base shear capacity, whereas IS 456-2000 exhibited superior ductility and flexibility. SNI 2847-2019 and NZS 3101:2006 delivered balanced performance in terms of stiffness and material efficiency. The variation in slab thickness, reinforcement area, and natural period highlighted each code’s design philosophy regarding seismic safety. These findings suggest that code selection should consider regional seismic risk, structural demands, and construction priorities to ensure optimal safety and efficiency. The study contributes to the harmonization of global flat slab design practices and offers practical recommendations for improving the seismic resilience of buildings.
