QMiX CONCRETE
FND4 Concrete Supplier
FND4 concrete from QMiX Concrete is a high-performance sulphate-resistant foundation concrete designed for use in highly aggressive ground conditions where significant sulphate concentrations may be present in soil or groundwater.
FND4 is typically specified where a Design Chemical (DC) class of DC-4 has been identified following a ground investigation. At this level of chemical exposure, selecting the correct foundation concrete is critical to protect structural elements from long-term chemical attack and deterioration.
FND4 concrete can be supplied as ready-mix concrete or volumetric concrete, providing flexibility based on access, pour size, and site requirements.
QMiX FND4 concrete typically achieves an indicative compressive strength of approximately 30 N/mm² at 28 days, depending on specification.
