Ngati mumagula malonda kudzera mu umodzi mwamaulalo athu, BobVila.com ndi othandizana nawo atha kulandira ntchito.
Konkire ndi chinthu chokhazikika komanso chokhazikika. Ngakhale kuti simentiyi ndi zaka masauzande ambiri, konkire yamakono ya hydraulic inayamba kuoneka mu 1756. Nyumba za konkire zakale, milatho ndi malo ena adakalipo mpaka pano.
Koma konkire sichitha. Ming'alu yochitika mwachilengedwe, komanso ming'alu yobwera chifukwa chosapanga bwino, imachitika. Mwamwayi, zabwino kwambiri konkire ming'alu fillers akhoza kukonza ming'alu maziko, driveways, misewu, misewu, masitepe, etc., ndi kuwapangitsa pafupifupi kutha. Werengani kuti mudziwe zambiri za kukonza zinthu zosawoneka bwinozi komanso zina mwazabwino kwambiri zopangira ming'alu ya konkire pamsika kuti muchite ntchitoyi.
Pali zifukwa zambiri zomwe zimachitika ming'alu ya konkriti. Nthawi zina, kusintha kwachilengedwe pansi chifukwa cha kuzizira kwamadzi ndizomwe zimayambitsa. Konkire ikasakanikirana ndi madzi ochulukirapo kapena kuchiritsa mwachangu, ming'alu imatha kuwoneka. Mosasamala kanthu za momwe zinthu zilili, pali mankhwala apamwamba kwambiri omwe amatha kukonza ming'aluyi. Zotsatirazi ndi zinthu zomwe muyenera kukumbukira pogula.
Pali mitundu ingapo ya zomangira za konkriti, zina zomwe zili zoyenera kukonzanso kwamtundu wina kuposa zina.
Posankha chodzaza konkriti, m'lifupi mwa ming'alu ndi kuganizira kwakukulu. Poyerekeza ndi ming'alu yokulirapo komanso yokulirapo, ming'alu yabwino imafunikira njira ndi zida zosiyanasiyana.
Kwa ming'alu ya mizere yabwino, sankhani chosindikizira chamadzimadzi kapena chowonda chochepa, chomwe chimatha kuyenda mosavuta mu ming'alu ndikudzaza. Kwa ming'alu yapakatikati (pafupifupi mainchesi ¼ mpaka ½), zodzaza zokhuthala, monga ming'alu yolemera kapena zokonzera, zitha kufunikira.
Kwa ming'alu yokulirapo, konkriti yokhazikika mwachangu kapena kukonza konkriti kungakhale chisankho chabwino kwambiri. Zosakaniza zokhazikika za konkire zimathanso kugwira ntchitoyo, ndipo mutha kuzisakaniza ngati pakufunika kuti mudzaze ming'alu. Kugwiritsira ntchito finisher chithandizo chapamwamba kungathandize kubisala kukonza ndi kuonjezera mphamvu.
Zodzaza konkriti zonse ziyenera kukhala zosagwirizana ndi nyengo komanso zopanda madzi. Pakapita nthawi, madzi olowetsedwawo amachepetsa ubwino wa konkire, zomwe zimapangitsa kuti konkire iwonongeke komanso kusweka. Zosindikizira ndizofunikira makamaka pazifukwa izi chifukwa zimatha kudzaza ming'alu ndikuchepetsa porosity ya konkire yozungulira.
Chidziwitso kwa anthu akumpoto: M'madera ozizira kwambiri, kusunga madzi ndikofunika kwambiri. Madzi akalowa pamwamba pa konkire ndipo kutentha kumatsika pansi pa ziro, ayezi amapangidwa ndikukula. Izi zingayambitse ming'alu yambiri, kulephera kwa maziko ndi makoma akugwa. Madzi ozizira amathanso kukankhira midadada ya konkire kuchokera mumatope.
Chida chilichonse chimakhala ndi nthawi yake yochizira, yomwe ndi nthawi yomwe imafunika kuti iume kwathunthu ndikukonzekera magalimoto. Zida zina zimakhalanso ndi nthawi yoikika, zomwe zikutanthauza kuti sizimauma kwambiri koma sizisuntha kapena kuthamanga, ndipo zimatha ngakhale kupulumuka mvula yochepa.
Ngakhale opanga nthawi zambiri samatchula nthawi yokhazikitsa kapena kuchiritsa pofotokozera zamalonda, zinthu zambiri zapamwamba zimakhazikika pakadutsa ola limodzi ndikuchira pakangopita maola ochepa. Ngati mankhwalawa akuyenera kusakanikirana ndi madzi, kuchuluka kwa madzi ogwiritsidwa ntchito kudzakhala ndi zotsatira zina pa nthawi yochiritsa.
Musanayambe kukonza, chonde ganizirani nyengo ndi kutentha. Izi zimauma msanga nyengo yofunda-koma ngati mugwiritsa ntchito konkire, simukufuna kuti ziume mwachangu, apo ayi zidzang'ambikanso. Choncho, nyengo yotentha, mungafunikire kusunga ming'alu yokulirapo yonyowa.
Zambiri (koma osati zonse) zamadzimadzi, zosindikizira ndi zigamba zimasakanizidwa kale. Kusakaniza kowuma kumafuna madzi, ndiyeno kusakaniza ndi dzanja mpaka kugwirizana komwe kumafunidwa kukufika-izi zikhoza kukhala kuphatikiza kwa malingaliro a wopanga ndi mlingo wa kuyenda komwe mukufunikira. Ndi bwino kutsata njira yosakaniza momwe mungathere, koma ngati kuli kofunikira, mukhoza kuchepetsa kusakaniza ndi madzi owonjezera.
Pankhani ya utomoni wa epoxy, wogwiritsa ntchito amasakaniza utomoniwo ndi chowumitsa. Mwamwayi, utomoni wochuluka wa konkriti umakhala m’machubu okhala ndi milomo yodzisakaniza yokha. Chonde dziwani kuti mankhwalawa amatha kukhala ovuta kwambiri, chifukwa chake mumakhala ndi nthawi yochepa yokonza ntchito. Ndizofala m'makina okonzekera chifukwa amatha kuyika pamalo oyima ndikuletsa kulowa pansi pamadzi.
Pali njira zingapo zogwiritsira ntchito chodzaza konkriti chabwino kwambiri, ndipo njira yomwe mumasankha imadalira mankhwala ndi kukula kwake.
Madzi odzaza madzi amadzaza mumtsuko waung'ono ndipo amatha kudontha mosavuta m'ming'alu. Caulk ndi sealant angagwiritse ntchito mfuti ya caulking kuti athetse ming'alu yaying'ono mpaka yapakatikati. Zambiri mwazinthuzi zimakhalanso zodzikweza, zomwe zikutanthauza kuti ogwiritsa ntchito sayenera kuziphwanyitsa kuti zitsimikizike kuti zatha.
Ngati chosakaniza cha konkire kapena chigamba (chouma kapena chosakanikirana) chimagwiritsidwa ntchito pochiza ming'alu yayikulu, nthawi zambiri ndi bwino kugwiritsa ntchito trowel kapena putty mpeni kukankhira zinthuzo mu ming'alu ndi kusalaza pamwamba. Kumanganso kungafunike choyandama (chida chophwanyika, chotambalala chomwe chimagwiritsidwa ntchito kuphwanyila zida zomangira) kuti agwiritse ntchito zokutira zosalala, zofananira.
Chodzaza bwino kwambiri cha konkriti chimatha kupanga ming'alu yosawoneka bwino masana. Zotsatirazi zimatengedwa kuti ndizo zabwino kwambiri pamsika, koma posankha mankhwala abwino kwambiri a polojekiti yanu, onetsetsani kuti mukukumbukira zomwe zili pamwambazi.
Kaya ndi ming'alu yaying'ono kapena kusiyana kwakukulu, Sikaflex self-leveling sealant imatha kuthana nayo. Chogulitsacho chimatha kudzaza mipata mpaka mainchesi 1.5 m'lifupi pamalo opingasa monga pansi, mawayilesi, ndi masitepe. Pambuyo pochiritsidwa kwathunthu, imakhalabe yosinthika ndipo imatha kumizidwa kwathunthu m'madzi, ndikupangitsa kuti ikhale yoyenera kukonzanso dziwe kapena malo ena omwe ali ndi madzi.
Sikaflex imabwera mu chidebe cha 10 ounce chomwe chimakwanira mfuti yokhazikika. Ingofinyani mankhwalawo m'ming'alu, chifukwa cha khalidwe lake lodzipangira okha, pafupifupi palibe ntchito yofunikira kuti mupeze yunifolomu yomaliza. Sikaflex yochiritsidwa kwathunthu imatha kupakidwa utoto, utoto kapena kupukutidwa mpaka kumapeto komwe wogwiritsa ntchito amafunikira.
Kukonza konkriti kotsika mtengo kwa Sashco kumatsindika kwambiri kusinthasintha ndipo kumatha kutambasulidwa kuwirikiza katatu m'lifupi mwa ming'alu yokonzedwa. Chosindikizirachi chimatha kuthana ndi ming'alu mpaka mainchesi atatu m'mbali mwa misewu, masitepe, ma driveways, pansi, ndi malo ena opingasa a konkriti.
Paipi iyi ya 10 oz sealant imayikidwa mumfuti yokhazikika ndipo ndiyosavuta kuyenda, zomwe zimalola ogwiritsa ntchito kufinya muming'alu yayikulu ndi yaying'ono popanda kugwiritsa ntchito trowel kapena putty mpeni. Ikachiza, imasunga kukhazikika komanso kusinthasintha kuti isawonongeke chifukwa cha kuzizira kozizira. Chogulitsacho chikhoza kupakidwanso utoto, kotero ogwiritsa ntchito amatha kusakaniza cholumikizira chokonzekera ndi konkire yonse.
Kudzaza ming'alu ya konkire pamaziko nthawi zambiri kumafuna zinthu zopangidwa mwapadera, ndipo RadonSeal ndi chisankho chanzeru pantchitoyi. Chida chokonzekera chimagwiritsa ntchito thovu la epoxy ndi polyurethane kukonza ming'alu mpaka 1/2 inchi yokhuthala pamaziko apansi ndi makoma a konkriti.
Chidacho chimaphatikizapo machubu awiri a thovu a polyurethane odzaza ming'alu, doko la jakisoni kuti amamatire ku ming'alu, ndi magawo awiri a epoxy resin osindikiza ming'alu asanabadwe. Pali zinthu zokwanira kudzaza ming'alu mpaka 10 mapazi kutalika. Kukonza kudzaletsa madzi, tizilombo ndi mpweya wa nthaka kulowa pamaziko, kupangitsa nyumba kukhala yotetezeka komanso yowuma.
Polimbana ndi ming'alu yayikulu mu konkire kapena kusowa chinthu chamtengo wapatali, kukonzanso kungafunike zinthu zambiri, monga chigamba cha konkire cha Red Devil's 0644. Chogulitsacho chimabwera mubafa ya 1-quart, yosakanizidwa kale komanso yokonzeka kugwiritsidwa ntchito.
Red Devil Pre-Mixed Concrete Patch ndi yoyenera ming'alu ikuluikulu m'misewu, misewu ndi masitepe, komanso malo owonekera mkati ndi kunja. Kugwiritsa ntchito kumangofunika kuti wogwiritsa ntchito akankhire mng'alu ndi mpeni wa putty ndikuwongolera pamwamba. Mdyerekezi Wofiira ali ndi zomatira zabwino, zidzakhala zowala konkire mtundu pambuyo kuyanika, sangachepetse kapena kusweka, kuti akwaniritse kukonza kwanthawi yayitali.
Kung'amba kwa mizere yabwino kumakhala kovuta, ndipo kumafuna zinthu zamadzimadzi zocheperako kuti zilowe ndi kutseka mipata. Njira yamadzimadzi ya Bluestar's flexible crack filler imalowa m'ming'alu yaying'ono iyi kuti ipangitse kukonza kwanthawi yayitali ndikusunga kukhazikika pakatentha komanso kozizira.
Botolo la 1-pounds la crack filler ndilosavuta kugwiritsa ntchito: ingochotsani kapu pamphuno, finyani madziwo pa ming'alu, kenako ndikusalaza ndi mpeni wa putty. Akachiza, wogwiritsa ntchitoyo amatha kujambula kuti agwirizane ndi pamwamba pa konkire, ndipo khalani otsimikiza kuti kukonzako kudzateteza tizilombo, udzu ndi madzi kulowa.
Chosindikizira cha Dap chodziyimira pawokha ndichofunika kuyesa kukonza mwachangu komanso kosatha ming'alu ya konkire yopingasa. chubu cha sealant ichi ndi choyenera kwa mfuti za caulking, ndizosavuta kufinya mu ming'alu, ndipo zimangowonjezera kuti zitheke kukonza bwino komanso yunifolomu.
Chosindikiziracho chikhoza kukhala chopanda madzi komanso chopanda nyengo mkati mwa maola a 3, ndipo wogwiritsa ntchito akhoza kujambula mkati mwa ola la 1 kuti akonze mwamsanga ming'alu yomwe ili pamwamba pa miyala yopingasa. Njirayi imapangidwanso kuti iteteze mildew ndi mildew, zomwe zimapangitsa kuti zikhale zoyenera kumalo onyowa.
Nthawi ikafika, Drylok's 00917 simenti ya hydraulic WTPRRF dry mix ndiyofunika kuiganizira. Kusakaniza kumeneku kumalimba mu maminiti a 5 ndipo kuli koyenera kukonzanso malo osiyanasiyana omanga.
Kusakaniza kwa simenti ya hydraulic iyi kumapakidwa mumtsuko wa mapaundi 4 ndipo amagwiritsidwa ntchito kukonzanso ming'alu yamiyala, makoma a njerwa ndi malo a konkire. Ikhozanso kukonza zitsulo (monga njerwa) pamwamba pa konkire kuti zikonzedwe kwa nthawi yaitali. Pambuyo pochiritsa, zinthu zomwe zimachokera zimakhala zolimba kwambiri komanso zolimba, zimatha kuletsa mpweya wa nthaka ndikuletsa madzi opitilira 3,000 kuti asadutse m'ming'alu kapena mabowo.
Ndizovuta kupeza mankhwala omwe ali amphamvu komanso ochiritsa mwachangu, koma PC Products PC-Concrete Two-Part Epoxy imayang'ana zonse ziwiri nthawi imodzi. Epoxy ya magawo awiriwa imatha kukonza ming'alu kapena zitsulo zozikika (monga ma bolts ndi zida zina) kukhala konkriti, ndikupangitsa kuti ikhale yolimba katatu kuposa konkriti yomwe imamatira. Komanso, ndi nthawi yochiritsa ya mphindi 20 ndi nthawi yochiritsa ya maola 4, imatha kumaliza ntchito yolemetsa mwachangu.
Epoxy ya magawo awiriwa imayikidwa mu chubu cha 8.6 ounce chomwe chimatha kulowetsedwa mumfuti yokhazikika. Mphuno yosakaniza yosakaniza imamasula ogwiritsa ntchito kuti asadandaule za kusakaniza zigawo ziwirizo molondola. The epoxy resin yochiritsidwa imakhala yopanda madzi ndipo imamizidwa mokwanira m'madzi, ndipo imatha kugwiritsidwa ntchito m'misewu, ma driveways, makoma apansi, maziko ndi malo ena a konkriti.
Kudzaza ming'alu yayikulu, madontho akuya, kapena malo opanda zinthu ndi caulk kapena madzi kungakhale kovuta. Mwamwayi, kukonza kwa Concrete Super Patch ya Damtite kumatha kuthetsa mavuto akulu onsewa ndi zina zambiri. Kukonzekera kwamadzi kumeneku kumagwiritsa ntchito njira yapadera yosachepera yomwe ingagwiritsidwe ntchito pa 1 inchi wandiweyani wa konkriti mpaka mainchesi atatu.
Chida chokonzekera chimabwera ndi mapaundi a 6 a ufa wokonza ndi 1 pint ya zowonjezera zamadzimadzi, kotero ogwiritsa ntchito amatha kukonza kapena kukonzanso pamwamba pa konkire malinga ndi momwe angafunikire kusakaniza. Kuti mufotokozere, chimodzi mwazotengerazo chidzaphimba mabwalo okwana 3 masikweya, ma driveways, kapena malo ena a konkire okwana 1/4 inchi. Wogwiritsa ntchitoyo azigwiritsa ntchito mng'alu kapena pamwamba pa ming'aluyo.
Ngakhale tsopano muli ndi chidziwitso chochuluka chokhudza makina abwino kwambiri a konkriti, mafunso ambiri angabwere. Onani mayankho a mafunso otsatirawa.
Njira yosavuta yodzaza ming'alu ya mizere yabwino ndi kugwiritsa ntchito zofiyira zamadzimadzi. Finyani dontho la zodzaza pamng'alu, ndiyeno gwiritsani ntchito trowel kukankhira chodzaza mu mng'alu.
Zimatengera zinthu, m'lifupi mwake, komanso kutentha kwake. Zodzaza zina zimauma mkati mwa ola limodzi, pomwe zodzaza zina zingafunike maola 24 kapena kupitilira apo kuti achire.
Njira yosavuta yochotsera chodzaza konkriti ndikugwiritsa ntchito chopukusira ngodya ndikupera m'mphepete mwa chodzaza.
