advise on building a wall,

[Johny Walker]

need some advise on building a wall, it needs to be very strong, its not a supporting wall,its only 9ft x 4ft

1, would it be stronger using 9" hollow block with steel bars & filled with conrete.

2,double skinned 5" blocks with cavity & steel bars then fiiled with concret

Hi Johny what's it for mate thanks Jon

The second choice would be stronger also using wall ties across the cavity.

Strong in which direction though? Concrete blocks will resist compressive force to a huge extent (ie load bearing) but will crack easily under tension. That's why steel is used to reinforce, as steel is much better at not snapping when pulled.

 

I assume you are meaning strong as in to be able to withstand a sideways force rather than downwards weight?

 

In which case my main thought would be to get as much steel into it as possible, whichever option you go for! However you will need steel running horizontally as well as vertically ( no good just putting rebar rods down the cavities inside the blocks as that will just give strong "pillars" IMO.

 

As an alternative to blocks, could you not consider getting some steel mesh reinforcement and plywood, then shuttering a wall out of solid concrete with at least one layer of steel mesh inside?

Hard to design a wall when you don't know what it's for. If it's a retainer, 100mm dense concrete laid on there backs Is good to about 4ft. Cavity is pointless in a retainer make it solid and strong. More info please

its to go between to containers .

that means nothing,

 

are you using the wall to retain anything or is it a feature ?

how high does it need to be ?

 

A non retaining wall can be a single skin of brick (100mm) but doesn't look nice, a double skin at 9"will give you a much more appealing finish and is good at retain things like lawns and raised boarders to a heigh of 1-1.5mtr.

Anything over that or with a mass behind it will need a 18" retainer minimum and possible steel to reinforce.

Why?

Don't they like each other?

if you cant help please dont comment ,

 

its NOT a supporting wall ,its going between 2, containers do try & think outside the box ,

Concrete Panels are the easiest way to make a wall, just put two vertical steels in the ground and slap the panel up against them.
