It's because of the terrain of the land. The land is downward sloping to the back where my ongoing project is. I was not the Engineer that handled the project so I can't say much on it. Thanks

Pls what is the thickness of this iron bars? What is the thickness of the stirrups? What is the spacing between these stirrups to each other?

Akerewe:

Pls what is the thickness of this iron bars? What is the thickness of the stirrups? What is the spacing between these stirrups to each other?

Stirrups space_40cm
Iron bar_10mm to ring 16mm Column
8mm to ring 12mm column
Either 8mm or Quarter rod to ring 12mm windows/Doors beams

Foundations Filled and Manually Rammed.
First Stage of Plumbing work done.

olukaygold:

Stirrups _12mm
Iron bar_10mm to ring 16mm Column
8mm to ring 12mm column
Either 8mm or Quarter rod to ring 12mm windows/Doors beams

Oh! Thanks Chief, u mean it's not possible for 8mm ring stirrups to hold 16mm pillars bar?

Akerewe:

You can sir, infact 8mm is the minimum for Stirrups but you'll need accurate spacing of 40cm(16". But For 10mm, I always use 51cm(20".

Is 40cm not too much?
I plan using 200mm for the stirrups on 16mm tiger TMT bar

Who recommended it? The spacing can go between 40cm-60cm. But if you can afford it to be 20cm Stirrups space,then you're Good to Go.

Actually it's for a storey building, I read it online that it should be around 20cm for a storey building especially for columns.
No whaala, it's just a small building inside a well populated city. When we have big one, no wahala. Noted!

Not all these online stories You've to be following because they only drop reviews based on the kinds Project they're Handling, I.e You can't compare Reinforcement Columns of 6Story Building with the way you'd reinforce a 1story building. The stirrups spacing of 10cm is not for a Story building.Involve a Professional Builder on your building or atleast ask two or more Artisans for reviews, if not, You'd spend more/Waste Money on Materials when handling it by Yourself.

Ok no wahala, noted. Although my engineer said it could be 300 or thereabouts, but I decided to leave it like that.

Moreso, what is ur view about the mixing ratio of sharp sand 5 headpan, granite 3/4 size 4 headpan, 1 bag if cement.
Thanks engineer

You misinterpreted the Mixing Proportion sir, 3headpan(Sand), 6headpan(Granite),1bag of cement which is 1:2:3(M20 Grade) Is okay for a story building sir.
Modified
It's 1:1.5:3 concrete mixing ratio for M20 strength Grades
Though I go for M15 strength Grades.

Thanks Chief, really appreciate

Pls engineer which one is better for columns and beam for a storey building? 3/4 granite size or or 1inch granite size and what is the right mixing ratio for each of the size

Akerewe:

Depending on the size of your columns, and beams. 3/4 granite size is the standard size for a story building sir.

Hmm, I av a serious problem with this oo. I ordered for a 3/4 granite yesterday the bricklayer told the supplier to supply 1 inch and he obliged oo. What can I do now now with this 1 inch granite supplied!

You can manage it sir, but try to follow 30cm stirrups spaceing for foundation columns and 40cm stirrups spacing after DPC,this would prevent skipping/hanging when pouring the concrete. Pls try to text or call me for any enquiry, I'm offering free consultation. my thread is already derailed sir

Thanks Chief engineer, God bless you immensely for the insight.
Pls what is the long time adverse effects of using this size of 1 inch granite for columns for a storey building? What is the acceptable mixing ratio for this size to achieve the best strength? For the spacing see below picture, it's already at 203mm (8 inches) on 16mm tiger TMT Bar
