Greenbloc – frequently asked questions

CCP Greenbloc technology is based on reducing cement which is the key material in concrete that contributes the highest amount of carbon. We replace the cement with low and ultra-low carbon cement alternative materials that can be manipulated to perform in the same way as cement.

How do we achieve the carbon saving?

CCP Greenbloc technology is based on reducing cement which is the key material in concrete that contributes the highest amount of carbon. We replace the cement with low and ultra-low carbon cement alternative materials that can be manipulated to perform in the same way as cement.

I’m a builders merchant. Will I have to stock two types of block – a standard OPC block and a lower carbon Greenbloc?

No, you will only need to stock one block as the blocks from CCP are low carbon as standard. This means that you can stock just one type of block from your yard which will cater for those customers who want a lower carbon option, but you can also sell the same block for those customers who just want a concrete block and aren’t concerned about sustainability (even though they should be).

Do your standard blocks which feature the Greenbloc technology have the same fire resistance as a conventional block?

Yes they do. There is no difference. All Greenbloc products perform to the same specification, performance, quality and aesthetic characteristics as 100% cement versions.

Do your blocks have the same u value?

Yes they do. Our low carbon Greenbloc blocks have the same performance, same cost and lower carbon footprint.

Will the blocks last as long?

Yes they will. All Greenbloc products perform to the same specification, performance, quality and aesthetic characteristics as 100% cement versions.

Environmental Product Declaration

To verify our carbon reduction claims we have 3rd party verified EPD (Environment Product Declaration) to prove that our carbon reduction values and data are as specified and reported.

Why don’t you just offset the carbon using a tree planting scheme?

We believe that is more important to try and reduce our carbon emissions in the first place, to stop them getting into the atmosphere, rather than simply planting trees to compensate for our own emissions.

Planting trees does play a part in a more sustainable future, but needs to be done in addition to us reducing carbon emissions, not instead of.

Does using recycled aggregates in the block lower the carbon footprint?

Although the use of recycled aggregates sounds attractive, their use can actually result in an increase in carbon within the block. Typically the use of recycled aggregates results in the need for a higher amount of cement to be used to compensate for the reduced performance, compared with using virgin materials. The higher the cement content, the higher the amount of carbon in the block.

All of our Greenbloc products contain a percentage of carefully specified and screened recycled materials as a replacement for virgin aggregates. These choices ensure there is no compromise on our carbon embodiment targets and our Greenbloc technology has been specifically designed to work with these materials , whilst at the same time, helping us to achieve our carbon reduction targets.

We have an EPD (Environment Product Declaration) to verify that we can still maintain a low and ultra-low carbon embodiment whilst incorporating recycled materials. If you’re trying to compare different eco concrete blocks always ask to see the manufacturers EPD to verify the product claims.

Do I use the same type of mortar as I would with my current blocks?

Yes you do, there is no need to change how you use the block in a project. All Greenbloc products perform to the same specification, performance, quality and aesthetic characteristics as 100% cement versions.
