Comparative Analysis of Concrete Mix Design Methods: SNI 03-2834-2000 vs. SNI 7656:2012

Abstract

Concrete mix design is a critical facet of construction, determining the composition of concrete for optimal performance and durability. This research paper presents a comprehensive comparative analysis of concrete mix designs based on two prominent Indonesian standards: SNI 03-2834-2000 and SNI 7656:2012. The study evaluates these standards in terms of technical accuracy and economic viability, shedding light on their effectiveness in producing efficient and sustainable concrete mixtures. The analysis encompasses various parameters, including slump value, aggregate sizes, water-cement ratio, and aggregate content. Notably, the research delves into the weight-based method and the absolute volume method as specified in the standards. Detailed calculations and considerations are undertaken to explore the differences and convergences in mix designs under the two standards. The study's findings reveal intriguing insights. The alignment of concrete masses obtained from both standards underscores their reliability and compatibility. Similarly, the agreement in water-cement ratios emphasizes the fundamental principles shared by these standards. However, the research unveils nuanced variations in the aggregate content between the weight-based and absolute volume methods, opening discussions on their distinct abilities to capture aggregate intricacies. Incorporating an economic analysis based on standard unit prices, the research highlights the financial implications of the different mix designs. The cost-effectiveness of SNI 7656:2012, which entails reduced cement usage while producing heavier concrete, introduces a sustainable perspective by minimizing material consumption. The synthesis of technical precision and economic feasibility forms the crux of this study's insights. As the construction industry seeks optimal mix designs that balance performance, durability, and sustainability, this research offers guidance to engineers and practitioners. In an era of evolving construction practices, where resource efficiency is paramount, this study contributes to the discourse on concrete mix design, enriching decision-making for resilient and cost-effective construction practices.
