Types of Sand and gravel

nick 56

Can anybody give me a quick guide (or point me to a web site) to the types of sand and gravel and their uses.

I will be going to builder’s providers in North Dublin and buying it in ton bags. I hate going in and not knowing the name of that which I need.

I understand it is graded by grain size starting with “builders Gravel” for strong concrete. Beyond that I am unsure. I saw for example on one site some really fine sand such as you would see in a child's play pit.

The jobs are in my back garden and is for general jobs such as paths, block laying, etc.

Thanks Nick

On the sand anyway a rough guide

Dead or pit - for putting around ducts
Sharp - for concrete
Builders- for mortar
Plasterers- for plaster

BUT you can get very dirty builders sand so I'd often use plasterers sand for muck
And a very big sharp sand can leave concrete hard to finish.

"Hardcore
A term that has unfortunately been usurped by the porn industry and which provides a constant source of amusement to me when I see the web logs for just how many saddoes have used their one free hand to surf over to this site in search of hardcore, only to find a pile of old bricks and broken concrete."

:pac:

I was talking to a Brit the other day about concrete sub bases and he used the term MOT for clause 804 even though apparently UK and Ireland share the same technical terms in road construction.

while may not be directly relevant to the OP's post, just to say that we have moved on from "804" post pyrite
Irish Standard I.S. 888:2016 applies for under concrete floors and footpaths, which includes this piece
Order the material in accordance with the project specfication i.e. I.S. EN 13242 and S.R. 21 Annex E. Communicate clearly the intended end-use "UNBOUND GRANULAR FILL (HARDCORE) FOR USE UNDER CONCRETE FLOORS AND FOOTPATHS, - T0 Struc, T1 Struc, T2 Perm, or T3 Blind " as appropriate.
