Heidelberg Low Carbon Sulfate Resisting Cement 25kg Bag

Heidelberg Low Carbon Sulfate Resisting Cement 25kg Bag

Heidelberg Low Carbon Sulfate Resisting Cement is designed to deliver the strength and performance of traditional CEM I cement while significantly reducing embodied CO₂. This makes it a more sustainable choice for both commercial and domestic construction. It is suitable for use in concrete, mortar, and grout, and can be applied above or below ground — including areas exposed to high sulfate levels. Designated as CEM III/A +SR under BS 8500, this cement offers reliable sulfate resistance for most environments (excluding class DC-4m). It also enhances chloride resistance and helps minimise the risk of alkali-silica reaction, meaning it can be safely used with high-reactivity aggregates. The result is a durable, long-lasting cement suitable for demanding conditions.

FAQs

Where can this sulfate-resisting cement be used?

It is suitable for most environments, including high-sulfate soils and below-ground applications. It should not be used in the most extreme sulfate class (DC-4m).

Is this cement a more eco-friendly option?

Yes. It has significantly lower embodied CO₂ compared to traditional CEM I, making it a more sustainable choice without reducing performance.

Does this cement help prevent concrete deterioration?

Yes. It improves chloride resistance, reduces sulfate attack, and helps prevent alkali-silica reaction, contributing to long-term durability.
