Konkire: Buku Lothandizira kwa Oyamba

Konkriti ndi chinthu chosunthika komanso chokhazikika chomwe chimagwiritsidwa ntchito pomanga zosiyanasiyana.Kaya ndinu okonda DIY kapena katswiri wa zomangamanga, ndikofunikira kumvetsetsa konkriti ndi katundu wake.Muchitsogozo chomaliza cha oyamba kumene, tikambirana zonse zomwe muyenera kudziwa zokhudza konkire, kuphatikizapo zomwe zili, momwe zimapangidwira, mitundu ya konkire, ndi ntchito ya cellulose ether mu konkire.

Kodi Konkire ndi chiyani?

Konkire ndi chisakanizo cha simenti, madzi, zophatikizika (monga mchenga, miyala, kapena miyala yophwanyidwa), ndi zina zowonjezera mankhwala.Zosakaniza izi zikasakanizidwa palimodzi, kusintha kwa mankhwala kumachitika, zomwe zimapangitsa kuti zikhale zolimba komanso zolimba.Mphamvu ndi kulimba kwa konkire zimadalira ubwino ndi kuchuluka kwa zosakaniza zomwe zimagwiritsidwa ntchito.

Kodi Konkire Amapangidwa Bwanji?

Njira yopangira konkriti imaphatikizapo njira zingapo.Chinthu choyamba ndikusakaniza simenti, madzi, ndi zophatikizana moyenerera kuti mupange phala.Phalalo limayikidwa mu nkhungu kapena formwork ndikuloledwa kuumitsa kapena kuchiritsa.Konkire ikatha, nkhungu kapena mawonekedwe amachotsedwa, ndipo konkire yakonzeka kugwiritsidwa ntchito.

Mitundu ya Konkire:

Pali mitundu ingapo ya konkriti, iliyonse ili ndi mawonekedwe ake apadera komanso ntchito zake.Ena mwa mitundu yodziwika bwino ya konkriti ndi:

1. Normal Strength Concrete: Konkire yamphamvu yokhazikika ndi mtundu wodziwika bwino wa konkriti womwe umagwiritsidwa ntchito pomanga.Ili ndi mphamvu yopondereza ya 2500-5000 psi.
2. Konkriti Wamphamvu Kwambiri: Konkriti yamphamvu kwambiri imagwiritsidwa ntchito pamapulogalamu pomwe pamafunika mphamvu zambiri.Ili ndi mphamvu yopondereza ya 10,000-20,000 psi.
3. Konkire Yopepuka: Konkire yopepuka imagwiritsidwa ntchito popanga zinthu zomwe zimadetsa nkhawa.Zimapangidwa pogwiritsa ntchito ma aggregates opepuka monga shale, dongo, kapena slate.
4. Konkire Yodziphatika: Konkire yodzipangira yokha ndi mtundu wapadera wa konkire womwe umayenda ndikudziphatika pawokha, popanda kufunikira kwa kugwedezeka.
5. Fiber-Reinforced Concrete: Konkire yowonjezeredwa ndi fiber ndi mtundu wa konkire womwe umalimbikitsidwa ndi ulusi, monga chitsulo, galasi, kapena ulusi wopangira, kuti ukhale wabwino.

Udindo wa Cellulose Ether mu Konkire:

Cellulose ether ndi chowonjezera cha mankhwala chomwe chimagwiritsidwa ntchito mu konkire kuti chiwongolere katundu wake.Ndi polima yosungunuka m'madzi yomwe imatha kuwonjezeredwa kusakaniza konkire kuti ipititse patsogolo kugwira ntchito kwake, kuchepetsa kuyamwa kwamadzi, ndikuwonjezera mphamvu ndi kulimba kwake.

Zina mwa njira zomwe cellulose ether ingathandizire kukonza konkriti ndi izi:

1. Kupititsa patsogolo Kugwira Ntchito: Ma cellulose ether amatha kusintha magwiridwe antchito a konkriti, kupangitsa kuti ikhale yosavuta kuyiyika ndikumaliza.
2. Kuchepetsa Kutsekemera kwa Madzi: Ma cellulose ether amatha kuchepetsa kuchuluka kwa madzi omwe amatengedwa ndi konkire, zomwe zimapangitsa kuti zikhale zosagwirizana ndi kuzizira komanso kuchepetsa chiopsezo cha kusweka.
3. Kuchulukitsa Mphamvu ndi Kukhalitsa: Ma cellulose ether amatha kuwonjezera mphamvu ndi kulimba kwa konkire, kuwongolera kukana kwake ku abrasion, kukhudzidwa, ndi kuukira kwa mankhwala.
4. Kumamatira Kwambiri: Ma cellulose ether amatha kukulitsa kumamatira kwa konkire kumalo ena, kupititsa patsogolo mphamvu zake zomangira ndikuchepetsa chiopsezo cha delamination.

Pomaliza:

Pomaliza, konkriti ndi chinthu chosunthika komanso chokhazikika chomwe chimagwiritsidwa ntchito pamapangidwe osiyanasiyana.Kumvetsetsa katundu wa konkire ndi udindo wa cellulose ether mu ntchito yake ndizofunikira kwa aliyense wogwira ntchito ndi konkire.Posankha konkriti yoyenera ndikuphatikiza cellulose ether mumsanganizo, mutha kukonza magwiridwe antchito, mphamvu, komanso kulimba kwa zomanga zanu.
