Slab concrete pouring

[earthlyken]

Hello mga fellow tsikoters,

May quick question lang ako, kasi regarding buhos ng 2nd floor slab..

Manual kasi gagawin ng mga tauhan namin, mga nasa 70sqm ang area bubuhusan nila ng semento, now my question here..

Kailangan ba nila buhusan lahat in a day? Or pwede half the area muna then bukas ulit yung other half?

Any inputs would be greatly appreciated..

Kasi ang sabi sakin ng foreman ko ay pwede raw half muna then bukas yung other half, my point here is that pano nila e half yun?

Sa malilit na floor slab pwede po basta ung floor slab mo ay suported ng beam, normally ung sa ibabaw ng beam ang putol.

Sample, ang bubuhusan mo ay 2.5m x 7.5m, ang beams mo ay every 2.5m, pwede po na ang buhusan mo muna ay 2.5m x 2.5m.


Pero pag malaking area, ung magkakalayo ang beams mo, mahirap po pag naputol ang buhos bago umabot sa beam, consult po ninyo sa civil engineer na gumawa po ng design ng haws nyo kung saan safe. Pero it is cheaper to hire additional manpower para isang buhusan lang.

[CoDer]

Pwede yan basta ang putol eh sa beam.

[earthlyken]

That you sa reply, ang ibig niyo niyo po sabihin ay sa gitna ng beam ang half buhos? Or before mag beam?


Also hinde poba ma sacrifice ung tibay nun pag half half yung buhos?

If 4inches lang ang thickness ng floor slab mo sir, kayang kaya yan buhusan ng minsanan coz that is more or less be equal to about 7 cu. m. of concrete plus of course volume of concrete required for the beams and columns. By doing this, you can avoid "cold joints" or "construction joint/s" and have your floor slab "monolithic". Better add some extra manpower and hire a one bagger mixer to do this. hope to help.....

Ok lang yan basta gitna ng beam ang putol, walang sacrifice sa tibay yan.

Although since 70sqm lang naman yung bubuhusan nyo eh mas maganda kung buo na.

[yebo]

kaya yan 1 day, dagdag ka ng tao saka mixer. parehas din naman gastos mo sa manpower, kasi imbes na 2 days bayaran mo maging 1 day na lang doble lang tao.

^Dapat i-charge niyo na ng consultation fees si TS para sa house construction nila. :D

I agree that this can be done in one day basta maayos yung pag-prepare ng forms na bubuhusan.

[Manilablock]

mas makakatipid ka kung isang buhusan lang, isipin mo per hour ang bayad sa tao, plus kung sa 2nd day ung mga construction boys mo ay magsabi na masakit ang katawan nila at hindi makapagtrabaho, paano na ang floor slab mo? helper lang naman ang idadagdag mo, ung taga halo at taga deliver ng concrete.

Saka after buhos normally day-off ang mga tao para rest while curing ung concrete, except meron sila magagawang iba sa haws mo na kakain ng 1 day.

Ok na yung poste then their planning to buhos the beam but d sagad para may maisingit ung mga bar para mabuhusan yung flooring ng 2nd floor, kaso ang sabi nila ay to save mga coco lumber raw ay half now and half the nextday ung buhos ng flooring.. ok lang bayun na ganun procedure? Am just curious kung pano nila buhosan half ng biga? Lalagyan ng harang yung other half ng biga?

[yebo]

ano? tipid ng cocolumber? so para tipid e 1/2 lang ang buhusan then ililipat agad sa next 1/2 yung cocolumber? e hindi pa naman pwede alisin agad yung scaffolding sa ilalim nun hindi pa cured yun, mga 1 week pa yun bago fully cured. sigurado ka ba dyan sa contractor/foreman mo?

[chrismarte]

wag ka na muna magpa buhos TS unahin mo palitan yung foreman mo. pag pag one day pa lang nalis na yung mga porma gumuho na!

Agree ako sa iba buhusan at tapusin mo nang isang araw.

O.T. lang sir ano po ba mas cheaper yung slab concrete flooring or kung PRE-FAB nalang ang gagamitin?

Prefab kung sakto yung specs sa house niyo. The shortcoming of prefab (i.e. Vazbilt) is that there's a set size/dimension and construction design to follow since it follows mass production. This limits the freedom of you layout and design. I've seen some prefab houses before and they look okay.

When I had our house extension built, 2nd floor concrete slab was poured and finished within one day, I rented a 1 bag mixer, and around 10 guys to haul up the concrete. Work started 7 am, up to around 10 pm, nonstop. Same with our third floor, except that I added 2 more guys to man the block and tackle for winching up the concrete buckets.

If you stop halfway, chances of your roof having a water leak is more likely. Cement will crack on the jointed part. I suggest you do it in one pass. Be prepared to feed them, merienda, lunch, dinner, energy drinks, cold water, etc. Well fed, ang mga construction workers hataw lang ng hataw yan. My concrete slabs are now crack free.

My 2 cents.

Hampasin mo sa ulo yang foreman mo, di pa cured yan the next day tapos tangalan nya na ng support.

^ I think your foreman does not know what he is talking about. Baka nagma-marunong lang yan, mahirap kung gumuho ang slab, back to square one ka nyan. And sayang ang pera on materials.

I left the slabs to cure for 1 week, before we removed the scaffolds. Hindi din namin tinangal lahat, para may support pa rin on the stress and critical areas.

[earthlyken]

Good day,

thank you guys for inputs, sorry mali pala ako pagkaintindi sa foreman ko, yung mga biga pala sinasabi niya na 1 side muna then after 2 days tangal na yung box then lipat sa kabilang side na biga naman, then after 2 days ay mag foform naraw sila para sa floor slab na..

another question po is the stability to prevent cracks and leak, kasi sabi niya 1 side nila bubuhusan yung floor slab hangang sa hati ng biga then next day ulit the other side..

ok lang ba yung ganun procedure? or they really need to finish the buhos the entire day?

regarding sa cement mixer, sabi ng foreman ko wag naraw..para makatipid, kaya naman raw ng manual...

worry kolang kung baka magkaproblema ako sa katagalan kung half half yung buhos nila sa floor slab?

more inputs guys..TIA

SALAMAT Sir.....

Nga pala, if you can rent metal scaffolding, it would be a much cheaper (and sturdier) alternative to using cocolumber as concrete support. Not only is cocolumber getting expensive, you also have to buy nails and GI wire to secure them. This adds up to your cost, not to mention A LOT of used cocolumber afterwards.

If you want to rent, I can refer you to the hardware where I bought all my construction materials.
