Good evening family. Pls due to the price of 12mm my welder advise me to use 10mm for lintel work against 12mm.
Is this advisable

michlins:
well confirm the sizes. They make it 4ft for the entrance so you can move large properties like deep freezers and fridges

omanzo02:

I haven't had any problem move fridges or any furnitures through 3 or 3.5 ft entrances or door.

Ok sir. The quality of the constituents too matter though. I've not seen many good sharp sand around... not even the ones filled with mud/dirt that are sold in Ajah and Ikorodu.

______
Quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement (Balamurgan et al., 2013).
______
The compressive strength of concrete from stone powder showed 14.76% higher value than that of the concrete made of normal sand (Mahzuz et al., 2011). https://www.researchgate.net/publication/320213222_Parametric_Study_on_Quarry_Dust_and_Bacteria_in_Cement_Mortar_for_Next_Generation_A_Review

michlins:
that's ok. Ten single doors is what you need then

omanzo02:

The 4ft is double door or am I missing something?

I think you should elaborate on the quality of sharp sand used only for molding interlocks.

Apart from the others you've mentioned which are known to me. One can also used sharp sand and 3/8 coarse. Those in PHC who are familiar with it's usage understand. You only need to tell the person supplying the coarse sand the usage purpose to enable him bring the best quality.

1. I agree with you on the quality of sharp sand available. I expected that you’d have seen my comment where I mentioned that the best sharp sand is washed sand (I also put it in bracket like I am doing here -gutter sand). Unwashed sand contains silt and/or clay that reduce the quality of the resulting product.
2. The above papers you cited never mentioned complete replacement of fine aggregate with stone (quarry) dust. They all mentioned partial replacements (also which I mentioned). But you said you used stone dust only for your own interlocking blocks. Remember I advised him to include stone dust but not to use only stone dust.
3. Partially replacing sand with stone dust will definitely improve the quality of your concrete/blocks. This is because the dust will fill up voids between the sand (fine aggregates) particles. The less voids you have, the stronger your concrete/block although it is not the only factor contributing to concrete strength.
I have read theses and journals that place the optimum proportion of partial replacement between 30% and 40%. There is the tipping point after which the strength begins to decline with an increase in stone dust proportion.

Here is my journal article on blocks:

Hmmm.
It's even a bit proper to get the advice from an iron bender and not a welder.
If you use 10mm, you will be using more rods on each lintel compared to 12mm.
Well, let your engineer decide what to go for.

EgunMogaji2:


Please listen to your structural engineer. Don’t go with your welder abeg.

michlins:
yes the 4ft is the double doors, the single is 3ft.

The first is 4ft and the later picture is 3ft door

omanzo02:


Alright, I think the 3 ft seem perfect for the space I have, I would rather have a wider windows than door, ventilation is a daily occurrence than moving stuff.

sinorte:


Please I need help! We are at a DIY stage of this project.

What are the materials really required for the production of interlocking stones? I understand stone dust is better, and that's what we planned to use if not for cost. But can I really use sharp sand as substitute, just as the artisan suggested?

He's also positing that granite will form part of the mixture (when sand is used) to produce the stones. What granite size do you think is ideal? Please help me with these information. Na beg I dey.

Sir the house is bungalow, no structural engineer involved.
It's iron bender not welder

These are local wooden doors...they can pass for imported doors when completed.

Will share later.

Its 4 inches thick solid wood. Exposed to harsh weather conditions for more than 2 months before cutting to doors

CuteMaro:

This house looks good. Would love to see full photos of the front view of this house. Is it possible?

Focusmind:


Very correct. I wanted to ask the difference between a Welder and an Iron bender. My Structural Engineer goofed big time when I was building as I wasn't around when the building started up to decking level.

It was when we were about to do the decking that I called a seasoned iron bender, with a lot of construction experiences under his belt, to do the iron works for me. On getting to my site, because of some structural defects he saw, he advised places that we needed to put hidden beams, open beams and other reinforcement amendments to support the integrity of the building in certain places of the decking that were not in the structural plan as the building is a lengthy one.

My "COREN" registered structural Engineer agreed with him completely. That was how the building was saved. Since then, I had relied on the iron bender for certain things pertaining to the building.

YeyeBoyfriend:
good morning sir, how much for the 4ft and 3ft doors respectively?

michlins:
40,000 and 30,000 respectively
