Quality Concrete Standards According to SNI and ASTM: Why Do You Need Solutions from Conmix Indonesia?

In the world of construction, the strength of a building greatly depends on the quality of the concrete used. To ensure safety and long-term durability, construction practitioners in Indonesia refer to standard benchmarks, namely SNI (Indonesian National Standards) and ASTM (American Society for Testing and Materials). However, the question is: what are the criteria for concrete that is considered “good” according to these standards?

Criteria for Quality Concrete According to International Standards

Good concrete is not only hard, but must also meet the following technical parameters:

1. Workability: Based on ASTM C143, concrete must have the right slump value. This means that concrete must be easy to pour and compact without causing particle separation (segregation).
2. Compressive Strength: According to SNI 2847:2019, concrete must be able to withstand the planned load after reaching 28 days of age. Concrete that fails to achieve this compressive strength risks causing structural failure.
3. Durability: Concrete must be resistant to extreme environments, such as high humidity, sulfate attack, or corrosion of reinforcing steel.
4. Efficient Water Content: The water-to-cement ratio must be kept to a minimum. The less water used (without reducing workability), the stronger the final result.

Challenges in the Field and Concrete Admixture Solutions

Consistently achieving SNI or ASTM standards in the field is not easy. The hot weather in Indonesia often causes concrete to harden too quickly before it can be leveled. This is where Concrete Admixture or chemical additives play an important role.

PT Far East Conmix Indonesia is a trusted partner in addressing these challenges. As a specialist concrete admixture manufacturer, Conmix provides products specifically designed to help contractors meet strict technical specifications.
