boss you are doing a great job here i have been following your thread now i need your help please can you tell how many trips of sand that can fill a 4bedroom bungalow i have paid for 10trips it could not even filled the sitting room and the guest room please i need your help thank you.

Bro! sorry to distract u from ur nice work, buh I still insist u get this one wrong. The relative densities of these materials are already constant. Batching by weight involves weighing these constituents of concrete in that ratio, that is, 50kg of cement, plus 100kg of sand(0.1tons), with 200kg(0.2tons) of aggregate.

While by volume is using a head pan of cement to 2head pans of sand and 4of granite/gravel. And only few people batch by weight except big batching plants.

Also, isolated bases, remain isolated bases, standard works requires form works and prepared specially.

Thumbs up for ur first-class, e no easy!

Thank you my brother for the positive criticism.

I know whar you talking about sir.
For example, if I want batch 1cubic meters of concrete using 1:2:4 by standard I know I will use 6 1/2 bags of cement and more (may be due to shrinkage and wastage).

I will ask make sure that water to cement ratio is kept @ not more than 0.65.

After I get my quantities of cement for one cubic meters, I will multiply that by 2, and then convert the result into tonnage. With this expression = N x 2 x 50/1000

Since I don't have weighing balance on site, all I need to know is the relative density of the particular sand I am using. Assuming I am using a sand of relative density of 1.7

From the relationship between, relative density = weight /volume, I can get the volume of sand required.

I then measured my container or bucket, diameter and height to calculate the volume of bucket to know the volume of sand that the bucket can lift at a point.

Estimating gravel required also follow similar approach.

After all these operation I can now established a means based on volume and my 1: 2 : 4 by weight with water cement ratio 0.65 may be 1: 1.5:3 by volume.

yak:
how far has this project gone and how much is spent so far?

Many at times we waste so much materials on building in Nigeria, yet without realising structures that can stand the test of time - citing the number of caved building stories that abounds.

In the cause of my globetrotting, I have realized that in many countries they do not waste money on german floors for residential duplexes and even in some industrial buildings as we do in this country, yet you will never see or hear about buildings collapsed stories like we have in this country.

We sure have shortage of qualified indigenous professionals and quality raw materials.

your works here are generally poor starting from foundation excavation, blinding, bar placement, the oversight concrete, to the d.p.c block work,also your mix ratio is something else even when you claim its 1:2:4,the work here are generally poor.next time try to consult an experienced and COREN certified structural Engr to guide you properly to avoid hard I known. thanks.

podosci:
Thanks spotting the mistake...

Mailthaddeus:
Another thing again is that u claim to use an isolated and pad footing foundation yet, I can't clearly see ur 1.2x1.2m pad form. All am seeing is basket placed directly on blinding. This is wrong construction. The need to use expert and certified civil and building engineers in any project cannot be over emphasized.
Now, of what use is the plinth beams to this structure at dat level of d dpm? It wuld bear more loaad of that beam ws at d base of d foundation tieing the bases of the pads together. And in this case, shuld be Tie/link beams. And the blocks can now sit on d beam.

We take so many things for granted because Nigeria is blessed wit good and stable soil, else so many collapses will be happening daily.

Mailthaddeus:
bro! I can't see 1:2:4 by weight here, rather am seeing by volume. Where is ur weighing balance u use to confirm it's by weight? U did by volume not weight. jst to correct this mistake. Thank u

johnson232:
ok sir... maybe cost restrict people.

don't know if u will be kind enough to recommend a good waterproof cement, want to use it for my sceptic tank plastering.

mavverick:
Just the guy you need.
abdulwastecx, with this kind of pressure on the ground, what does it mean in terms of constructing what will carry the tanks.

NLresidentQS:
Hello Sirs.

Please help here. A project I'm involved in, an irrigation project somewhere in the North. We have a large fabricated steel tank ( Dia - 11m, height - 6m) is to rest on the ground.

Now we thought we could place them in a ground slab (say 150mm thickness, BRC mesh reinforced) on well compacted Hardcore.

Bit others (professionals too) are arguing that the slab will collapse. If it collapse? Does it mean the tank will sink into the ground?

Ground bearing capacity is over 200

One person was even saying we will need a heavily reinforced slab with downstand beams on pad?

@all please input is needed.

Nice our able mathematical engineer.

What's the cost and structural implication for a bungalow with all external walls made of sandcrete blocks and all internal wall made of polystyrene? Is there any significant cost/efficiency savings? Will this accommodate conduit wiring and mechanical pipping? If the walls are not to be rendered, how do you fill the gap/chink between two polystyrene board?

Further if one adopts all internal polystyrene walls, what's will be the lintel method? How do you tie the roof to the structure?

diordaves:
So do you render (plaster) the Polystyrene? can the wall take minimal impact from moving house furniture? can one hang kitchen wall units, flat screen TVs, wall mirrors and family photos on the wall? Will there be crack maps on the polystyrene wall with time? How cost effective if just limited companies produce the product in Nigeria?

Can you please dwell on this polystyrene alternative a bit more extensively? We could be on to something here in building temporary houses in Abuja.

karleone:
Hello Abdulwastecx,

What partition wall material would you advise an office owner to use in creating office partitions? Some research suggested PVC is bad as it's not good for health.
Do you mind referring me to any good one?
Thanks.

Abdul,.. Over to you

@Brabus:
is there no way the Frame below (from your pix) can be achieved without cutting and re-welding the iron?
I have Pressure./Press moulding in mind. So as to still maintain uniform structural strength.

Also, what is the thickness of the H-frame used?

I am sure other builders are learning new things from you.



Lastpage!

laideh:
Please, why?

laideh:
Nice thread, great job.

Please, what's the meaning of that thing written on the wall with red paint?

johnson232:
these works are extremely neat i must say... i thought the plinth beam is only for the exterior walls?

twinskenny:
Boss good luck on this one... Benin is a lovely city

abouzaid:
nice work but you didn't state your foundation depth.

emmadejust:
following....

abdulwastecx I'm signing in fully.
I hope say form never finish...
