00:31.5
So yung mga nandyan sa loob na loose na gravel
00:33.9
Dapat maalis tong mga to yung loose na cement bits
00:37.3
Dapat wala rin sa loob nyan
00:39.6
Kasi pag binuusan nyo to nang meron yan
00:41.9
Hindi na maganda yung adhesion ng newly poured concrete natin dito sa base
00:46.2
So very very important yun my dudes
00:48.0
Now pagkatapos linisin yung ilalim ng ating column
00:51.2
Papalagyan na namin ng anillo or column ties itong ating column
00:55.6
So yung nga anillo yung spacing nyan ay
00:57.9
Dinidictate ng inyong civil engineer or structural engineer
01:02.2
And kung anong klaseng anillo
01:03.9
Kasi usually meron tayo nitong outer na column tie
01:06.7
And then sometimes nilalagyan din ng mga ties na ganito sa gitna
01:10.1
Or may diamond tie sa gitna
01:11.8
Okay so dito may kita natin yung anillo ng ating mga columns
01:15.1
Na hindi pa sya nakakabit
01:16.1
So ganyan yung magkakagawa sa kanya
01:18.0
And very very important itong hook na ito my dudes
01:21.3
So may formula para dito
01:22.9
Ayan flash ko sa screen
01:24.1
So yung haba na yan ay hindi nyo dapat hinuhulaan
01:26.5
Kasi pag yan ay maikita
01:27.9
Pwedeng mag slip ito
01:29.5
At bumuka yung ating column causing in some serious failure
01:33.5
So you don't want that to happen
01:35.0
Kaya dapat kinocompute yan
01:36.5
And tama yung length nitong ating hook dito sa ating column ties
01:40.8
Now after lagyan yan ng anillo
01:43.3
Ay popormahan na natin tulad dito
01:46.1
So as you can see meron na tayong forms na nakakabit
01:48.7
And usually meron kaming mga interior forms
01:51.1
Ito and yung nasa kabila nya
01:52.8
And then meron kaming exterior forms
01:55.0
Kung saan sya yung nakatalukap dun sa ating interior forms
01:57.9
So sya yung maghahawak sa interior forms natin
01:59.9
Para hindi sya lumobo or pumotok palabas
02:02.8
Or lumikwak yung ating concrete pag binusa na natin sya
02:06.1
Usually pag makuporma ng mga poste
02:08.4
Ginagamit is mga phenolic boards or wood
02:11.1
Pero for us gumagamit kami nitong mga ganito
02:13.5
Ayan so steel forms sya
02:15.5
And the reason for that is because
02:17.2
Madalas kami nagkokonstruct ng mga bahay
02:19.7
So sayang naman kung one time use lang yung para sa mga poste
02:24.6
Also useful ito pag multiple levels yung bahay nyo
02:27.2
Para reusable and you know
02:29.3
Save the environment and save your money
02:40.5
Okay so tulad ng sinasabi ko bago tayo na-distract is
02:44.1
Yung pinanghahawak namin itong forms para hindi bumuka
02:46.8
Ay meron tayong pipes dito
02:48.2
Then meron syang mga clamps tulad nito
02:52.5
Now itong mga pipes and clamps na ito yung purpose nyan
02:54.9
Ay para pag binusa na natin ng concrete sa loob
02:57.1
Ay hindi bumuka or lumigwak itong ating columns
03:00.2
So yung mga yan hindi pa yung sapat
03:02.0
Nilalagyan namin sya ng supports sa labas
03:04.6
Para hindi rin tumumba yung ating columns
03:06.7
So that is what you see here
03:07.9
Meron tayong mga supports
03:09.5
And isa sa mga lagi kong nakakalimutan nung bago pa lang ako
03:13.2
Ay pag tinignan natin sa gilid
03:14.8
May kita nyo dyan may butas-butas itong ating columns
03:17.6
Ang purpose nyan ay dyan ilalagay yung wall dowels natin
03:20.8
Para embedded na rin sya sa ating columns
03:23.5
So meron tayong bakal na lalabas dyan
03:25.8
Okay so itong mga nakalawit-lawit na bakal na ito
03:28.4
Yung dowel na sinasabi ko my dudes
03:30.2
And yung purpose nyan ay sya yung kakabitan namin
03:32.7
Yung horizontal rebars para sa ating walls
03:36.1
Naka-embed na yan dun sa
03:37.4
Naglag yung brain ko
03:38.8
Naka-embed na yan dun sa ating poste
03:41.4
Mas matibay sya as compared sa nakadrill lang
03:44.1
So imagine nyo na lang meron tayong forms
03:46.1
So yung dowel natin ay nakaganyan sa loob ng ating poste
03:49.5
And yung purpose niyang pael na yan
03:51.0
Ay para hindi basta-basta mabubunot itong ating dowel rebar
03:57.3
Okay my dudes so after natin formahan yung ating poste
04:00.8
Ay iti-check nyo dapat yan ulit
04:03.1
Kung meron syang malalaki na butas-butas
04:05.2
And what we do dito sa site namin
04:07.5
Ay pinapasakan lang namin yung malalaking butas-butas na yun
04:10.3
Nung mga naka-crumple up na paper bag nung cement
04:14.3
So after you check all of that
04:16.5
And after nyo na ilagay
04:17.8
Yung mga dowels natin
04:19.6
Ay pwede na sya buhusan
04:25.8
So we are back sa site my dudes
04:35.2
Dahil today ngayong araw is the day of the buhusization of our columns
04:39.9
So buhusan na natin yung columns
04:41.4
Actually nabuhusan na namin yung dalawa doon
04:44.0
Hindi nakapag-record kasi medyo maingay
04:46.0
Pero do not worry kasi meron tayo ditong dalawa pa na hindi pa namin nabubuhusan
04:50.7
Now isa sa mga bagay na pinapagawa ko
04:53.1
Bago rin buhusan ay kung titignan natin dito sa inyo
04:55.8
May pinaglagay akong parang cement barrier
04:58.9
Doon sa connection ng ating slab at ng ating forms
05:01.8
And yung purpose nyan ay para
05:03.3
Pag binuhusan natin ito nung concrete mixture
05:05.6
Ay hindi lumabas yung cement
05:07.2
Dahil pag nangyari yun magkakaroon tayo ng honeycombbing
05:10.0
Dito sa ilalim na part na ito
05:11.6
Which is one of the worst parts
05:13.0
Na magkaroon kayo ng honeycombbing
05:15.5
And yung rason ba't nagka-honeycombbing
05:17.1
Again ay dahil lumabas na lahat nung semento natin
05:20.1
At natira na lang yung graba sa loob
05:22.6
So wala nang strength yung ganon
05:24.2
Now that we have a concrete mixture
05:25.8
We still have a few more steps to do
05:29.3
Bago tayo magbuho
05:30.5
So first step na dapat natin gagawin
05:32.8
Ay babasain natin yung surface
05:35.4
Kung saan magkakontak yung new cement
05:38.2
Or new concrete mixture natin
05:40.1
So in the case of our columns
05:41.8
Yung surface na yun ay itong slab
05:44.0
So dyan tatama yung grout
05:46.1
Dapat babasain natin itong surface na ito
05:50.8
Dahil pag di natin yan binasa
05:52.6
At binuhusan natin sya ng grout or concrete
05:55.8
To absorb agad nitong surface na ito
05:57.5
Yung moisture from that concrete
05:59.3
Mangyari doon na hindi na ganong kaganda
06:01.3
Yung band nitong ating slab surface
06:04.1
And yung newly poured na concrete
06:06.2
So that is also important my dudes
06:08.3
Then after natin basain yun
06:10.4
We move on to the next step
06:12.2
Which is adding grout
06:14.1
So what is grout?
06:15.5
Hindi ito yung nilalagay natin doon sa pagitan
06:17.3
Nung ating tiles my dudes na tile grout
06:19.0
Grout is basically a cement mixture
06:21.1
So semento sya and water
06:23.0
Pinaghalo natin boom pineapple
06:24.7
May nakakagets pa ba nung
06:26.8
Feeling ko walang makakagets
06:31.3
Anyway cement, water, boom, grout
06:34.5
And dapat yung consistency nito ay parang toothpaste
06:38.0
And yung purpose nung ating grout ay
06:39.7
It is going to serve as a bonding agent
06:42.1
In between yung new concrete mixture natin
06:44.7
And itong existing na dried concrete
06:48.2
So dito may kita na natin yung ating grout mixture
06:50.8
Brought to us by our in-house expert mason
06:55.1
So ayan yung consistency nya may kita nyo is
06:57.7
Medyo malapot sya na parang toothpaste
07:00.7
So yan yung ibubuhos natin sa loob ng ating forms
07:04.0
May tanong ang ating videographer slash video editor na si Ian
07:08.0
So kaway ka naman dyan
07:10.6
So tanong niya gano daw katagal bago ito matuyo
07:13.6
Actually after a day, tuyo na yan
07:15.8
But hindi porke tuyo ay pwede mo na syang galawin
07:19.7
Kasi ang ating column dapat hahayaan natin mag-cure yung concrete niya
07:24.5
So drying and curing are different things
07:27.4
So ang curing time ng columns is usually 21 days to a month
07:32.1
Pero after 2 weeks, pwede na natin tanggalin yung forms
07:39.0
Pwede na natin alisin yung ating forms dyan
07:42.0
But before 2 weeks, huwag niyong gagalawin itong ating columns
07:45.5
And avoid introducing unnecessary vibrations
07:48.4
Cause that is going to weaken our concrete
07:52.3
Tuyo na sya after 1 day
07:53.6
So pwede na syang
07:54.5
Maulanan after a day
07:55.8
But hindi sya pwedeng istorbohin
08:01.9
So marami sa inyo nagtatanong mayroon kung anong mga mixture ginagamit ko para sa ating columns
08:13.3
And dun sa ating slabs
08:14.4
So the mixture specifically na ginamit namin para sa columns is
08:17.8
1 is to 1.5 is to 3
08:19.9
Which is a class AA sya na concrete mixture
08:22.9
So ano ba itong 1 is to 1.5 is to 3
08:24.5
So 1 stands for isang bag ng semento natin right here
08:29.4
1.5 ay yung ating buhangin
08:32.2
So 1.5 bags ng buhangin or 1.5 cubic feet ng buhangin
08:37.0
And then yung 3 natin ay ang graba
08:38.9
So tatlong bag ng graba
08:40.5
Now itong mga sako namin ay measured yan na dapat 1 cubic foot yung laman nya
08:46.4
So hindi lang pwede sako kayo ng sako ng graba
08:48.7
Kasi sako are not made the same
08:50.9
Pinanganak sila na iba iba
08:52.3
May mas gwapong sako
08:53.5
May mas payat na sako na graba
08:54.5
May mas matabang sako
08:55.8
So kailangan ime-measure nyo pa ito sa measuring box na
08:58.5
1 foot by 1 foot by 1 foot or 1 cubic foot
09:01.6
Okay so ayan may kita natin nagbubuhos na sila
09:04.1
So yung ginagawang ngayon ni Manong Julius na parang nagbabarena sya
09:08.0
Binavibrate nya yung concrete natin with a concrete vibrator
09:11.7
Para mawalan ng air bubbles
09:13.8
Because we don't want air bubbles in our concrete mixture
09:16.5
Kung mapapansin nyo dito my dude
09:18.1
Bakit itong poste natin dito ay kalahati lang
09:20.9
So the reason bakit kalahati lang yung forms natin dito ay
09:24.5
Pag magbubuhos kayo ng column
09:26.1
Meron syang maximum amount of free fall height
09:28.6
Pagdating sa concrete
09:29.5
So what does that mean?
09:30.6
So yun yung height kung saan pag binuhos natin yung semento
09:34.1
And that height is 3 feet to 5 feet
09:36.9
So hula ko 5 feet to kasi 6 footer ako eh
09:39.9
Natatawa si Manong Manny
09:45.9
So ayan may kita natin around 5 feet ito
09:51.5
Dahil pag mas mataas pa dyan at nagbuhos tayo
09:53.9
Ang mangyayari ay maghihiwala yung concrete natin sa ating mga graba
09:57.3
And we don't want that to happen
09:59.0
Kasi makompromise yung structural strength ng ating concrete
10:03.3
So itong binubusan nila ngayon
10:05.6
Nabuhusan na yung kalahati nyan
10:07.4
Ngayon the upper half na yung binubusan nila
10:10.1
So may kita nyo mayroon din tayong parang salodon
10:12.6
So usually pag nasa tube yung concrete nyo
10:15.7
Pwede nyo pahabain yung free fall height nya
10:18.2
As long as nasa loob sya ng tube at pinapump yun
10:21.1
So yung free fall height is from a point
10:23.7
Kung saan yung concrete mag isa na lang nya
10:26.7
So that is the free fall height
10:28.0
3 feet to 5 feet or 0.9 meters to 1.5 meters
10:32.3
Okay mayroon so nakalimutan ko rin i-mention dito sa video
10:37.0
Na yung poste na yun ay after namin buhusan yung kalahati
10:39.8
Na less than 5 feet
10:40.9
Nilagay namin agad yung form sa taas
10:43.0
At tinuloy namin sya buhusan
10:44.9
So continuous namin sya binubusan
10:46.8
Kasi yung mga columns
10:47.8
Mas ideal na isang buhusan lang ito
10:51.0
Or monolithic yung ating column
10:54.4
One thing lang my dudes
11:04.9
Pag gumagamit kayo ng concrete vibrator
11:06.9
Ay huwag nyo sasobrahan din na i-vibrate
11:08.9
Or pag nagsisiksik kayo kamit ng mga rods
11:11.3
Ay huwag nyo dadamihan yung pagsiksik
11:13.4
At huwag nyo tatagalan yung pag-vibrate
11:15.4
Dahil ang mangyayari ulit
11:16.5
Ay maghihiwala yung ating concrete
11:18.2
And yung aggregates
11:19.2
Again ayaw natin mangyayari yun
11:22.6
But if you don't have a concrete vibrator
11:23.7
May putol yung column nyo
11:24.6
So dapat alam din nung nagva-vibrate
11:27.8
Kung kailan na sya titigil
11:29.7
One more thing my dudes
11:38.2
So isa pang bagay my dudes
11:39.5
Kung papansinin nyo
11:40.5
Meron tayong hacks na ginawa dito sa column
11:42.7
So kung i-zoom in natin dyan sa taas
11:44.3
May kita nyo ay may balde tayo ng pintura
11:46.7
Na may butas-butas
11:48.4
And ang purpose nun ay
11:49.5
Lalagyan natin yung ng tubig sa loob
11:51.9
And magdi-drip sya
11:55.4
Lagi kong sinasabi yung mga concrete
11:57.1
Na bagong buhos natin
11:59.6
So yung purpose nung balde na yun
12:00.8
Ay para continuously may tubig
12:02.6
Na bumababa dito sa ating poste
12:04.5
So yun yung isa rin sa mga rason
12:12.5
Ay para ma-achieve nga
12:13.7
Yung maximum strength nya
12:15.6
So na-imagine kung mag-introduce kami
12:20.2
Baka ma-copyright ako
12:22.3
Ito na lang akong kakanta
12:25.4
So I can stand by
12:31.9
So I guess that is it my dudes
12:33.5
Hanggang sa susunod natin na site visit
