Silly Question

[Richard]

Where would you use screed as opposed to just concrete. I know screed contains sharp sand but what applications would you use each for.

It is usually used for the top couple of inches of a solid floor. It gives a smoother finish than concrete because there aren't any stones in it.

I think screed is used on top of the concrete to give the finished level for flooring, usually when tiles are to be installed, so it would be a thin layer. Sharp sand would be the aggregate rather than stone. This may not be fully correct as there has been an amount of wine involved.%-)

50mm is usual

Yes 1(of cement):3-4 (sand) would be normal.

Screed is a much wekare mix than concrete and contains no stones.

I've been using a 10:1 mix of sharp sand and cement to bed stone slabs on.

Its striong enough, but concrete it ain't. Its cheaper as teh cement is tehbig cost.

Its porous because teh faps between teh sand grains are not totally filled with cement.

If you like, screed is simply snad loosely bound together with cement.

In flloring its normally mixed fairly dry as well, so it has no tendency to slump. Then its sweated with a float to bring the water to the top and create a sligthly better surface finish.

I'd say 5:1 is about right for floors.
