ST Concrete Mixes
ST mixes are a series of standard concrete grades used primarily for non-structural applications. They are prescribed by their cement content and aggregate ratios rather than compressive strength. This makes them a straightforward choice for many everyday building tasks where a simple, dependable mix is required.
Predefined & Consistent – Easy to specify and order with no complex calculations required.
Reliable Performance – Designed to meet general building and groundwork needs.
Cost-Effective – A practical solution for non-structural applications.
Wide Availability – Commonly stocked and delivered quickly across sites.
