[AstonHill]

I had a look a Jewsons web site and for a 25KG bag of Cement thy dont tell me the area it covers

So if I want 1 part cement; 2 part sand; and 4 part agregates
And i am filling 4 windows up with a total of 1013109 cubic cm, any ideas please on how much matirial to buy?

Thanks

A million cc is 1 cubic metre. 1 cube of concrete weighs about 2.4 tonnes. On a 1:1:2:4 with ratio that's about 300kg of cement, 300kg of water, 600kg of sand and 1.2tonnes of aggregate

ps; is it really that volume? Have you 4 windows that are approximately 1m x 1m, walls 250mm thick plus insulation??

You're better off not buying any.

The normal method is using brick/block

One million, thirteen thousand, one hundred and nine cubic centimetres. Are you sure about that? Just get a metre of ready mixed delivered.

Don’t you like windows?


are you centimetres just to confuse us? (I know it’s seems a bit odd, but mms and metres are the recommended units of linear measurement rather than the cm)

Bailiffs can smash through them and get him out though.

But then you've got to run round like a blue horse fly loading 2 and a half tons of concrete into shuttered portholes quick quick before it goes off and paying waiting charge if you're too slow. That may be a big ask. Mixing yourself means you can take a bit more time at it

I'm all for ready mix in a slab, but hoisting it to a height.. needs thinking about

He's got the other squatters to help him.

nah, who needs those silly blocks that are self supporting….vertical concreting is the way forward.

ICF FTW

Until ya get greedy with the amount you can pour in the day and burst the base

I just messured the windows and times by 3 and added them up
But its the inside frames of one large window, 2 medium and one small

I though pouring cement into them sanwitched by a board would be easyest and cheapest as not sure if room for blocks

Just to check here

Are you serious?

is that not wet with the weight of water

more then likely slightly less then a square meter and about 13-18cm thick
