Nice video sir. Correction po dapat po yun eh 0.02316 KPa para pag multiply ng 1000 eh MPa na sya. Salamat idol. The best ang video mo. Madami ako natutunan.

0.02316 GPa yon para maging 23.16 MPa

thank you Engr. Nakakatulog po ito lalo na saming Archi. students nakikita ko po yung practical since medyo lacking din po yung hands on experience for now. more videos pa po

[@claralearnandthrive]

DAY 1 - SECOND VIDEO ganda ng explanation mo po. nakakatulong lalo na sakin bilang studyante palang hehe

[@kwentonie-jayph8150]

Correction lng. Regarding sa pag.ahon ng sample sa curing tank. Kailangan iahon ang sample 24 hours bago mo ito itest. Iyon ay para matuyo ang sample at hindi basang basa ang sample pagdating sa testing center.. that is base on ASTM. Thanks

Good day engineer I have a question po.

[@mugiwarasensei2558]

Hi engr... tanong ko lang anong recommended slump po pag gagamit ng admixture..?

[@ARONJAMESGARCIA]

Depende po sa Design mix may ordinary mix at PCD, kung PCD 7" kung ordinary 4"

[@mugiwarasensei2558]

@ARONJAMESGARCIA Need an opinion engr. balak ko sa gumamit nga Admixture sa buildrite Rite mix PC100 , Class A mixture and W/c 0.5 job mix sa 1 bagger mixer.. wala po ba problem pag ng collapse ang slump as long as 0.5 or 20liters water lang nilagay... kasi nakita ko sa video nila na magiging workable yung concrete..

[@ARONJAMESGARCIA]

@mugiwarasensei2558 that is water reducing admixture, wala namang problem about the admixture, the problem is " Collapse slump" hindi siya acceptable. Paulit mo yung test hangang sa makuha mo yung tamang timpla kasi baka yung agreggates mo e basa hindi na uubra yang water cement ratio na ginamit mo, tantiyahin mo nlng yung tubig hangang sa makuha mo yung tamang timpla na sapat lng para maging workable at the same time maiswasan ang honey comb.

[@russurgelles6886]

sir pag tinest na cylinder sa testing center,ano ba dpat ,dpat ba mabasag sya or hindi dapat ?

[@ARONJAMESGARCIA]

Ganito Idol, kapag nareach niya na yung required strength at hindi pa nababasag at tumataas pa yung reading pwede na itong ihinto kahit hindi na ito antayin na mareach niya yung maximum Strength as long as umabot na sa required f'c, kapag bumababa na yung reading ibig sabihin basag na po yung sample,

[@richmillverosil3396]

Same lang po ba ang procedure pag beam sample ang gagawin ??

[@ARONJAMESGARCIA]

Magkaiba po kasi flexure po ang testing kapag Beam sample.

[@johnwick-gm4mw]

Good evez po Engr. Tanung lng po, anu po yung mga test na gagawin kung sakali man hindi papasa?

[@ARONJAMESGARCIA]

Kung sakali man hindi pumasa ang sample dahil sa improper sampling or pagkuha ng sample, meron tayong dalawang option, meron tayong tinatawag na destructive at at non destructive, usually itong non destructive ang ginagamit para maiwan ang pagkasira ng structural member 1.) Rebound hammer test 2.) Ultrasonic pulse Velocity - UPV test For destructive naman 1.) Coring

[@ARONJAMESGARCIA]

Para nman sa Slump test kung hindi man ito pumasa sa unang trial ng pag slump pwede itong ulitin, kung hindi parin pumasa, pwede nating itong dagdagan ng Admixture meron tayong water reducing Admixture at marami pang iba para makuha natin yung desired na slump na kailangan natin.

No, after taking a sample you can use or pour the concrete mix, but need to wait for the curing time and test result before heavy load applied to the Structure.
