ST Concrete Mix

ST Concrete Mix

ST (Standardized Prescribed) concrete mixes are tailored for non-reinforced applications that necessitate a specific mix ratio instead of strength classification. These mixes ensure consistent performance, durability, and ease of use for general construction, groundwork, and minor structural elements.

These mixes are particularly useful in projects where a consistent and reliable concrete composition is required without the need for structural reinforcement. Their prescribed ratios simplify batching and placement, making them a practical choice for foundations, kerb bedding, and general site preparation where ease of use and dependable performance are key.
