168 Mitigation Strategies For Plastic Shrinkage And Thermal Cracking I 🏠 Kembali ke Index 168 Mitigation Strategies For Plastic Shrinkage And Thermal Cracking I 168-Mitigation Strategies for Plastic Shrinkage and Thermal Cracking in Reinforced Concrete Columns: Advanced Formwork Detailing Rahasia Kolom Beton Mulus Tanpa Retak: Panduan Teknik Bekisting Anti Gagal untuk Bangunan Villa Premium di Bali Author: Edi Supriyanto Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ Abstract (English) Cracking in reinforced concrete columns is a significant concern for structural integrity and aesthetic longevity, particularly in the tropical climate of Bali. This paper investigates the role of formwork detailing in mitigating plastic shrinkage and thermal cracking. Through an analytical evaluation of formwork rigidity, moisture retention protocols, and thermal management within the column section, we identify key methodologies to prevent crack formation during the concrete setting stage. Adhering to SNI 2847:2019 and international performance standards (ACI 308), the study provides a technical blueprint for implementing anti-crack formwork systems, ensuring optimal structural performance and architectural finish. Abstrak (Bahasa Indonesia) Retak pada kolom beton bertulang merupakan kekhawatiran signifikan bagi integritas struktural dan keawetan estetika, terutama di iklim tropis Bali. Makalah ini menyelidiki peran detail bekisting dalam memitigasi retak susut plastik ( plastic shrinkage ) dan retak termal. Melalui evaluasi analitis terhadap kekakuan bekisting, protokol retensi kelembapan, dan manajemen termal di dalam penampang kolom, kami mengidentifikasi metodologi kunci untuk mencegah pembentukan retak selama tahap pengerasan beton. Dengan berpedoman pada SNI 2847:2019 dan standar kinerja internasional (ACI 308), studi ini menyediakan cetak biru teknis untuk menerapkan sistem bekisting anti-retak, memastikan kinerja struktural dan hasil akhir arsitektural yang optimal. 1. Introduction Plastic shrinkage cracking occurs when the rate of evaporation from the concrete surface exceeds the rate at which bleed water reaches the surface. In column construction, the formwork serves as both a structural mold and a moisture-retention barrier. Ensuring the formwork is properly sealed and moisture-regulated is the first line of defense against crack propagation. 2. Analytical Formulation and Thermal Management The internal temperature of the column section during hydration must be controlled. The maximum temperature differential $\Delta T$ within the column to avoid thermal cracking is calculated based on the modulus of elasticity $E_c$ and the coefficient of thermal expansion $\alpha$: $$\Delta T_{max} = \frac{f_t}{E_c \cdot \alpha \cdot K}$$ Where: $f_t$ = Tensile strength of concrete at early age ($MPa$) $E_c$ = Modulus of elasticity ($MPa$) $\alpha$ = Coefficient of thermal expansion ($^\circ C^{-1}$) $K$ = Restraint factor (ranging from 0 to 1) Maintaining this $\Delta T$ requires insulated formwork or controlled stripping times, which are essential components of an anti-crack methodology. 3.

Strategi Pencegahan Retak pada Kolom Pencegahan retak dimulai dari desain bekisting yang benar: Sealing yang Ketat: Mencegah kehilangan air secara dini akibat penguapan melalui celah sambungan bekisting. Manajemen Curing : Menggunakan teknik wet curing di dalam bekisting atau aplikasi curing compound segera setelah pembongkaran. Waktu Stripping yang Tepat: Tidak membongkar bekisting terlalu cepat saat hidrasi panas sedang mencapai puncak. 5. Mengapa Neurostruct? Masalah retak pada kolom bukan hanya masalah estetika, tetapi masalah durabilitas struktur. Neurostruct membantu Anda memetakan risiko retak sebelum pengecoran dimulai.
