Nothing special

The name Buhari makes some people to ejacul8

Yet some persons are fighting online for people already eating together

But the House they said was levelled down to pieces, has it resurrected? Hmm

It is well with Nigeria

Hmmm. Anything is possible

Nigerians are the best. One Love!!!

I like the artistic skills employed. However, our Jesus died at AGE 33 YEARS I don't get why pictures and images make him look like methuselah or Moses at old age

This is terrible . How come WE THE PEOPLE were blindly raped financially and we never knew?

Pmb must make sure we get to the bottom of this

Terrible

God help Nigeria
Nigerians help Nigeria

DonClerg:
Thank you very much.
1) Please how can one correct the errors in the images I sent?
2) Can it lead to the collapse of the building?
3) Can a slab with a very large area be partitioned with 9" blocks? The slab has Ly = 8.5 and Lx = 4.6. The slab was designed with Y12@ 200mm c/c both ways with a 150mm heigh. The contractor passed two internal beams(2Y16 T&B) at d middle of the Ly and Lx sides.
Will it hold if 9" blocks are used to partition rooms on it with a passage at one side?

1. I couldn't see the pictured properly so I do not really know what to say. Maybe if you send me pictures taken of the under of the slab and the columns I can say the corrections better.
2. Buildings do not always collapse due to such things except they are serious issues. However such negligence on the part of the artisans or the owner will definitely shorten the effective lifespan of the building and also result in cracks over time. But like I said it is when I get a clearer view of other structural elements that I can say categorically.
3. Secret beam is not efficient when the span is too long. I have explained before using a ruler as example. If you bend the ruler holding it when it is flat it bends easily. But Try to bend the ruler when held at the edge side and you find that it is not easy to bend.
What it means is that the secret/hidden beam and normal beam all require depth. The deeper the beam (effective depth), the stronger.
It is for this fact that secret beams are used when the span is short. Those who use secret/hidden/inner beams for long spans do not really have the grasp of the engineering behind it. With all due respects.

You want to demarcate the slab on top of the slab or under the slab? If it up, it will depend on the grade of concrete you used. The mix ratio. If it's standard 1:2:4, then you would have used 175mm or 200mm thick concrete to be on a safer side especially if you are using mallams to do the casting.
With a strong mix and proper casting, you can use 9 inches blocks to partition.

From my experience, i discovered that each case is different and the problems and solutions are different.

You just made a valid point. OP

Our enemies are not those ordinary Nigerians from other tribes who also face the same harsh economic situations as we face. Our enemies are Tribalism, Hate speeches, poor healthcare, bad roads, disunity, poverty, hunger etc. These real enemies do not differentiate between tribes and language.
Let us the youth be United to build a Great Nigeria where noone will be judged by where he or she comes from but by what he or she knows and can do.

[quote author=olumide4christ post=40792214][/quote]You and Hajji M have already given the right explanations. The Poker Vi.brat.or should be used in every concrete work. So many builders don't like to use it for columns and slabs and lintels. That is not good. Usually the intersection btw columns and beam and slabs have internal gaps that tapping or any other primitive method won't solve

Adek15:
pls can you explain to me concrete ratio mixture in details?

Concrete mix ratio is the ratio between the 3 component materials that make up the concrete. These materials are Cement:SharpSand:Granite.
So if we say concrete mix 1:2:4 what we mean is that for 1 measure of Cement, you mix 2 measures of Sharp sand and you add 4 measures of Granite.

Mix ratio works only if you are using the SAME container to do the measure. What I mean is that if you are using the paint rubber to mix, use the same paint rubber for everything. If you are using headpans use it for all the 3 different materials. If it is full wheel Barrow that you use to measure the 1 cement, use 2 wheel BARROW to measure sharp sand and 4 wheel barrows for granite. If you change the measure then you are not getting the strength required of that particular concrete grade (mix).
I decided to attach this analysis table to explain more. However it's not a perfect representation of what is in my heart but it's near-perfect

That guys response made me laugh. Loollllzzzz

Hmmmm. Who authorised you madam? Also how can you give a loan to fight terrorism? Can terrorism war repay it?

Hmmmm

MISMANAGEMENT
You couldn't manage a party yet you want to manage a Nation. No wonder we had so many uncompleted projects every part of Nigeria. Fashola, I don't envy you right now

I just tire for some Nairalanders self. Must you assume he is in your shoes?
Don't abuse someone you barely know. It's his money let him enjoy it in what will make him happy.
When your own dough comes, you can use it as you please

Great event for great achievers

Whenever i don't use Stonecoated for my roofs, I use Aluminium from a major city transported to the location.. Last time I roofed a house in Kogi and bought all the Aluminium from Abuja. The next project I am using Tower aluminium from Lagos.

The 1st point is that you can always get your materials from anywhere to use anywhere with little transport.

2nd point is that you don't use 0.45mm gauge. It's too thin. To me it makes noise during rainfall and it's weaker since its thinner.

3rd point is that since your roofing is in Enugu, simply contact 3 roofers who will submit quote then make comparison. The doubts you raised is because you haven't compared with others. And don't compare with website prices or with what someone else has done in the past. The situations and circumstances may differ well.

Vibrating machine is important because it removes air bubbles from the concrete, hence allowing the concrete to consolidate.

Correct explanations
Thanks.
