kevcos wrote: » Thanks for the replies but they are not really solving my riddle! Apologies if my question is hard to understand but basically 90% of concrete block twin leaf cavity wall constructed houses, built in Ireland over the pass few decades were build with a common standard 4" (440mm x 215mm x 100mm) concrete block. Now these blocks can come in various crushing strength; the typical block I am querying would be ~7.5n/mm (when used in an above ground instance) But in addition to being available in various strengths these blocks are also available in various densities. It is the density of those standard typical commonly used blocks which I am trying to find out. I don't live in Ireland any longer, if I did I could just pop into a quarry. And I can't determine from looking at Irish suppliers websites what density this particular block is; since I have moved away the available range of concrete blocks has expanded hugely so its hard to pick out what now is the former standard block. I think that the density is ~1500kg/m but I would like to be able to confirm this someway.

Going to a quarry would solve my query because I could simply ask what is the density of the standard block they sell. Yes I could do this over an email/phone, boards was my first port of call but I probably will end up doing so now.I need to know the density because blocks, in addition to strength, can also be specified and measured by density. I think this is a query for a blocklayer to solve.

In order to meet min TGD E regs, standard blocks tend to have to be >1900 kg/m3 a bog standard 7.5N concrete block will have a min density of 1900 kg/m3 some may be more depending on manufacturer conditions... but those only need to be shown to meet min standards. even 13N standard blocks have a density of min 1900 kg/m3http://qpulse.kilsaran.ie/QPulseDocumentService/Documents.svc/documents/active/attachment?number=DOC877 also, the blocks are usually manufactured and cured in factories, not quarries, so youd just be contacting the companies that we have already linked to in order to get the info you need.
