between hardcore and oversite concrete

Thank you sir, please after Will the hardcore cover even the foundation wall? And what is the ratio of mix for the hardcore (please state for bungalow and duplex)

Interiors

Were these interiors rendered with Atlantis or any other 3dmax?

abdulwastecx:
it is just a popular among building construction expert to interchanged those two. to me DPC ( damp proof course ) is a combination of a membrane use after filling (with leterite, hard core and sharp sand) and the concrete placed on top of that membrane basically to prevent moisture from rising through the foundation. basically it serve other structural purpose like allowing a uniform building level to be achieved after foundation, it also serve as tie to join the foundation wall together.
the BRC ( British reinforced mesh ) is introduced at the middle to prevent sinking under its own weight and cracking due to internal tension which may developed in the concrete.

summary. DPC = DPM + oversite concrete

Oga, when shall one apply that DPM (that nylon stuff), is it between hardcore and oversite concrete or before hardcore?

abdulwastecx:
mix ratio for foundation footing for bungalow should either be 1:3:6 or 1:2:4 for normal soil.
i prefer 1:2:4 ( 1 bag of cement : 4 head pan of sand or 1 wheel barrow of sand : 8 head pan of gravel or 2 wheel barrow of gravel). reason been that the foundation of bungalow is very important because it help to distributes the wall load to foundation adequately.
A typical foundations supporting a three bedroom flat or its equivalent should have the following features

1. minimum thickness of 100mm ( 4'') and should not more than 225mm (9'') thick on a strong soil for economy reason.
2. the sharp sand should not be too smooth and free from clay and other dirt which may reduce the strength of concrete
3. the gravel should be preferably 3/4 ( 20mm) thick and must be free from dust.
4. the water for mixing should be drinkable and free from salt and other chemical contamination
5. the water-cement ratio must not be greater than 0.6.


mode of calculating the volume of concrete for foundation footings ( strip foundation).
1. get the sum of the total gird of the substructure, let say 'P' = 50 ( example)
2. get the width of the foundation, say 450mm (18'') for 150mm ( 6" wall and 675mm ( 27" ) for 225mm (9" wall
3. Assume a thickness of say 150mm for 6" wall and or 225mm for 9" wall.
4. convert all your dimension to 'm'
5. hence volume, v =50x 0.45 x 0.15 = 3.375m3
6. increase the volume by 25% to cater for shrinkage and wastage. =1.25 x 3.375= 4.05m3

using mix ratio 1:2:4
part of cement = 1/7 x4.05 =0.58m3
since the density of ordinary Portland cement s 1506kg/m3
and i bag = 50kg
hence, no of bags = 0.58 x 1506/50 =17.4bags ( 18 bags aprox.)

part of sand = 2/7 x 4.05 =1.16m3
since the density of sharp sand is 1600kg/m3 and a tonne of sharp sand is 1000kg
hence, 1.16 x 1600/1000 = 1.856tonnes ( 2 tonnes aprox.)

part of gravel = 2 x 1.16 = 2.32m3
since the density of gravel is 2400kg/m3 and a tonne of gravel weight 1000kg
hence, 2.32 x 2.4 =5.57tonnes ( 6 tonnes )

part of water using water cement ratio of 0.6
weight of water = 0.6 weight of cement = 0.6 x 18 x 50 =540kg
volume of water required, from density = mass/volume
making volume subject, volume = mass/density
where density of water = 1000kg/m3
hence, volume of water required = 540/1000= 0.54m3
since,1m3 = 1000liters
volume of water required = 540 liters

Oga, I greet your office sir. That 'P' represents what sir, thank you.

Please guys, I just got a Z10 (T-Mobile, ST-3) it's still running on BB 10.0.1... I want to update it to 10.3.... how will I go about it cos it requires WIFI. I've got a Laptop, I use Glo bis, but I don't know how to get started. Please am a novice but not a dunce . Please help me out. And and...... my BlackBerry world setting doesn't have the second option that will enable me download more than 50mb. I need desperate help from guru in here. Should I scream HELP?

May our boat not sink

O meen! I refuse to fall. mbanu! i shall not!

uchennaakunne:
shut up what do you know?

Bia nwoke m, take your time o. No just talk to me anyhow.

What a disgrace to manhood

Oya make he treck from Lagos to America.

buygala:
You really want me to stalk you?


Then get some brains to match that fine face

There is nothing sadder in this life than watching a beautiful imbeciile dance naked in the marketplace

O boy, easy na. You just disorganized an already unorganized disorder. We love as the way the disorder take unorganized before. Thank you sir.

And what on earth are you guys insinuating Huuh? Toaster Toasting and Toastee Twirking.

This really bad. Just when I thought there was hope.

This is not cool at all.

ihebrooke:
No problems sir. Got no problem at all. How is work?

I thank God, you are blessed.

The girls's must be a big one, I can see that she's really thick.

ihebrooke:
You are welcome Sir

Oga sir, am very sorry for my earlier misconduct, I sincerely apologies.

Nneka123:
you deserve a slap!

why na

kikibabe:
lol

Are you really the girl on your profile?

Hehehehehehe

Lol

Na wa oooooo

Afam4eva and other Mod should move this to religion ASAP

.

Before the Oba stuff started, there were threads from Yorubas, threatening and insulting and forcing Igbo's to vote Ambode. Now their Oba has opened his amala and ewedu mouth to threaten the Igbo's as well (everywhere is burning). This buhari win has made them talkative overnight, insulting the Igbo's as they like (we cannot be pushed to the wall). I urge our Yoruba brothers and sisters to take it easy, they should apply their brakes cos over speed no dey pay.

akpumping7720:
Don't just try it again I beg. Insult me directly.

Did I insult your papa? Abeg take time and no let me vex

LFJ:
So this is one of the amenities you are talking about. You must be a comedian. worm

Am giving him an example of structures which a stranger in his home town have build in another land. I'll update you guys later on companies and other stuff by Igbos in other places.

akpumping7720:
Eeeeeh. Never in your miserable life mention my 'father' when exchanging words on a public forum like this. Biko, I take God beg u, I hate insult towards my family members. Talk to me in a more matured way and insult me directly, I will accept it.
And as per your 'Yoruba land came to light from Benin. What happened to 'The Creation of the earth started from Ile-Ife? You want to rewrite history?

This your Father thing pain u eeeeeeh! shioor! See warning

"Respectfully, We Igbos have always
overrated our significance in Nigeria. Since
the existence of this country, our
stubbornness have always made us the
best looser. We haven't taken a lesson from
Biafra, or the fact that we largely assisted
in relegating PDP to a regional party, or the
fact that our "myopic thinking" (in the
words of Rochas) have cost us the seats of
the Senate Presidency and House of Rep
Speaker.
But we gladly take a worthless pride in our
stupidity. NdiIgbos really need to look
inwards and cast the demon misdirecting
us away".
I quoted d above statement from a nairalander's comment on a particular topic today. Truth be said, d above statement needs to be written on a golden slate. The igbos need to look inwards if they really want to have a say in Nigeria politics. The average igbo is Proud and always full of himself. I respect the igbos a lot because they are very INDUSTRIOUS and INTELLIGENT. They have contributed a lot to the Nigerian economy directly and indirectly. There is no sector you wouldn't find an igbo man in Nigeria. But they have little say in the Nigeria Political system.
.Even almighty God himself respect HUMBLE people. Ojukwu can avoid d civil war if he hadn't prove stubborn that he can't receive order from Gowon because he is superior to him in rank, but truth be told, the Igbos need to learn the art of the game by learning how to be humble and loyal to other tribes. We have a saying in yoruba that 'if we should postrate for a dwarf, it doesn't mean that we will grow shorter when we get up'. Being loyal doesn't make you a 'butt licker'. Large deposit of oil is in the Niger Delta and not in the core east, that was why the presidency was zoned to them. It is true that Nigeria belongs to us all but there are some set of cabals that only revolution can cast them away, they determine who will be there and who is to come. The Ndigbos need to go back and learn how to play the card well. Buhari wouldn't have won if he didn't align with the Southwest to win the Presidency. If a yoruba man wants to get something that will be difficult for him to get, he doesn't mind calling d person daddy even if he is old enough to give birth to that person, he can even go as far as postrating just to get it. Let the igbos come together in one voice and support one of their own and do away with 'Pride', I believe if they can do this, they will one day Rule this nation and have a prolong say in the Nigeria Political System.
