Kumwa simenti pa 1 njerwa kiyubiki. Features wa mawerengedwe a, kuipa ndi ayamikira

Pamaso pa mwamuna weniweni mu moyo, pali zinthu zofunika zitatu zimene ali kuchita pofuna kutsimikizira kuti iwo ali kugonana wamphamvu. Ndipo ngati kubadwa ndipo analeredwa mwa mwana wake, komanso chodzala mtengo, kapena munda wonse, mavuto kungabuke, ndiye kuti akumanga nyumba - njira m'malo ovuta amene muyenera mwakhama kukonza nkhani ya makhalidwe abwino, ndi zambiri - ". Yophunzitsa"

The wamanga m'tsogolo ndondomeko za mavuto ambiri, wina wa mitu yomwe - kugula zipangizo yomanga. Bwinobwino vuto amafunika kukhala wokonzeka yomanga, zikuthandizani kudziwa chiwerengero cha njerwa, adzalola kuwerengera kumwa simenti pa 1 zomangamanga kiyubiki ndi M'sitolo chofunika kuchuluka kwa zigawo zina zofunika wa njira, kupewa ndowe zosafunika.

Mukufuna nyumba olimba? Nkhani molondola!

Professional zikugwira ntchito yomanga anthu ophunzitsidwa mwapadera. Ngakhale kuti athe bwino kuika pa njerwa, m'pofunika kuti ayambe zomangamanga. Kuyang'anira njira zonse pa akapitawo kumanga malo. Sazidziwa bwinobwino mu ntchito nzeru zonse zodcheskogo munthu zingaoneke kuti ntchito oterowo palibe lalikulu zambiri, koma kwenikweni, nyumba akhoza kumangidwa m'njira zosiyanasiyana, ndipo nthawi iliyonse m'pofunika kutsatira zina zabwino zambiri.

Mogwirizana zinthu monga zimachititsa chilumbachi kwa mtunda umene nyumbayi adzakhala ili, zikhalidwe zake nyengo. Zinthu zonsezi zimatengera pa njira imene adzapanga maziko a nyumba, kodi kuyika njerwa yothetsera adzakhala ogwirizana ndi miyala mzake. Kudziŵa mfundo zimenezi ena adzakuthandizani kumvetsa mochuluka bwanji polimbikitsa ndi zomangamanga, kodi makhalidwe ayenera njira kupanga makoma anali amphamvu, sanapereke ming'alu ndi kuwapotoza pambuyo pa nyengo yozizira, osati anaphimba efflorescence.

Osati mophweka

Zochokera pafupifupi zizindikiro zomwe zikusonyeza kuti zomangamanga wapangidwa m'lifupi wina njerwa (mbali yake yaitali 250 mm) pa mita lalikulu la mpanda ayenera njira ya pafupifupi 75 malita. Koma kumwa simenti pa 1 zomangamanga kiyubiki ngati perstenek wa mkati, zomwe kawiri kawiri zimachitika mu theka-njerwa, kapena unakhuthala akunja khoma 2-2.5 mwala?

Kudziwa kuchuluka kwa njira, choncho, koyenera kuti simenti kusanganikirana ake, mchenga, madzi ndi ena omwe si kuvomerezedwa, koma nthawi zina zofunika zigawo zikuluzikulu, ndikofunika kudziwa zinthu zochepa. Izi msoko makulidwe, kapangidwe ndi kukula njerwa, ndipo anapangira osakaniza palokha - chinthu chofunika kwambiri kulimbikitsa otaya simenti pa 1m3 ndi 1m2 zomangamanga njerwa osiyanasiyana.

Naŵa deta kuti kudzakhala kothandiza kuwerengetsera kuyambirira, koma m'pofunika kudziwa kuti ndi bwino nthawi zonse kugula zinthu ndi Kuwonjezera wa 10-15%, izo kuwateteza ku mpando kuyendera kumanga maziko.

Malinga pa gome, otaya pazipita simenti pa 1 kiyubiki cubes zomangamanga ndi 250, koma mtengo izi ndi zoona kwa mpanda kwambiri wandiweyani. Zimene anapezazo ndi kuti njira si anagulitsa kale osokonezeka, ndi zigawo zikuluzikulu si amayezedwa malita, ndi makilogalamu.

ndi njira yothetsera kuika ndi chiyani?

Tsiku ndi tsiku, yeniyeni, pamalo ena a zomangamanga, kawirikawiri kwa ogwira ntchito angathe kumva mawu monga akuti: "Ndipo Nditengereni chidebe yothetsera!". Kawirikawiri simenti kupempha mumtsuko, koma m'pofunika kudziŵa kuti popanda nthumwi kulumikiza kwa Kusakaniza mulinso zigawo zina. Pa nthawi yomweyo mu nkhani monga kumwa simenti pa zomangamanga kiyubiki, kuipa kwambiri njira, ndipo ngakhale adamuyimika kwa chilengedwe wangwiro, komabe zingasiyane pang'ono.

Pachikhalidwe njira tichipeza mwachindunji simenti, kumene kungakhale a sukulu zosiyanasiyana, kutanthauza osiyana linga zikuchokera. Zomangamanga anavomereza kuti atenge mtundu kuti kuwerenga M200 kapena M300, ndi zambiri "wamphamvu" polimbikitsa M500, nthawi wofunikila screed, kapena mapangidwe midadada konkire, maziko. zigawo zina optional monga mchenga ndi madzi. Choncho, chakale chilinganizo njira - 1 mbali simenti magawo anayi mchenga, madzi pafupi theka kulemera kwa simenti ndi.

Simenti simenti kusagwirizana

N'chifukwa chiyani kumwa simenti pa 1 zomangamanga kiyubiki - pafupifupi, ndipo musati mwachimbulimbuli kudalira njira pamwamba. Ngati akuganiza kulamula wolemera zofunika zofunika kusakaniza njira yothetsera - nkhani zambiri asavulaze omanga wosadziwa. Koma dongosolo la simenti, muyenera kudziwa kuti chogulitsidwa matumba, kulemera ndi makilogalamu 50. Ngati kuchita anapezazo ndi kulemera, ndi chiwiya chako chokandiramo ufa 1m3 njira zosonyeza M150 M400 simenti ayenera kutenga makilogalamu 400 simenti, ndi njira mphamvu ya 200 M mofanana makilogalamu 490 simenti zofunika. Pamene anagula simenti M 500, madziwo kulenga mtundu njira M 150 - 330 makilogalamu 200 M - 410 makilogalamu. Izi deta - kumwa simenti mu njerwa zomangamanga mu 1 kyubu, omwe achokera zizindikiro wamba nyumbayi.

subtleties kusinja

Sand - chachiwiri zofunika chigawo chimodzi - amadziwikanso zagwiridwa ndi zapansi ndipo maenje ndi kulemera. Nkhanizi kuchita ntchitoyi amafuna maulendo angapo, choncho kulankhula za kugula pa makilogalamu mchenga kosathandiza, zingakhale tani.

Akatswiri woyenera amakhulupirira kuti pamene kusakaniza mchenga ndi simenti matope n'kofunika kuti osakaniza abwino makulidwe, amene adzakhala omasuka ntchito ndi. Imakhala zofunika plasticity mchenga njira, pa dzanja linalo ali wabwino kwambiri simenti umapezeka, chifukwa cha zomwe particles sali oyenera kwambiri bwanji osalimba a kusakaniza.

The madzi mu njira adzakhetsedwa mu chakudya chochepa, potengera kulemera, koma osati kuchuluka kwa simenti. Komabe, simungathe kutsanulira madzi zonse mwakamodzi, kotero mulibe akonze zinthu, mobwerezabwereza kusakaniza mu zigawo zikuluzikulu pa diso. Popeza kuti n'zosatheka kuneneratu pasadakhale mmene mchenga woyera kudzakhala, kodi chinyezi ndipo nyengo yake zinthu, imene pomanga chichitike.

Komanso mchenga, madzi ndi simenti mu njira zikuchokera zingaphatikizepo zigawo zina: laimu, kusakaniza dothi kupewa yozizira koopsa wa osakaniza, komanso zina zomwe kupewa mapangidwe efflorescence (yochitidwa mawanga) pa makoma.

Njerwa ndi njerwa

Zingati simenti pa 1 kiyubiki njerwa zomangamanga, komanso zimadalira ndi zimene zomangamanga zipangizo ntchito ndi. Kugwiritsa njerwa chachikulu (imodzi ndi theka ndi awiri) kuchepetsa voliyumu ya njira, koma mawu zimenezi si zoona kwathunthu cha mwala dzenje. Ndi mtanda wa simenti pakuti ayenera kusamala kwambiri ndi osamala. osakaniza kwambiri madzi adzakhala kudutsa mu cavities, amene munazipereka kumatha zotsatira za kutchinjiriza phokoso ndi kutentha njerwa, ndipo kachiwiri, kumaonjezera otaya mchenga ndi simenti matope.

Akatswiri amalangiza kusinja osakaniza mogwirizana yakuti pa ntchito zinali zovuta kutsatira ndi trowel pa malo ntchito ya zomangamanga ndi mfundo Zipinda 'musakhale kumbuyo kusiya ntchito. Chimachititsa nsembe simenti chimadaliranso mmene njira umagwiritsidwa ntchito pa njerwa. Pakuti zomangamanga, umene kenako kubisika pansi chokongoletsera (zambali, kukongoletsa pulasitala, khoma pomangira) nthawi yokwanira kugwiritsa ntchito osakaniza simenti ku likulu la njerwa ndi. Ndiye apo palibe chifukwa choti kamangidwe ka malo, amenenso woyikidwa mfundo zenizeni kwambiri. Choncho, vertically anakonza kuti asapitirire m'lifupi mwake 8-15 mm, ndi yopingasa - 10-15 mm.

Malangizo

Polongosola mwachidule m'buku, tiona mfundo zingapo zofunika:

• Simenti - zakuthupi kuti kosamugonjera yosungirako yaitali. Ladzala ndi chinyezi, iye "dubeet" ndi kutembenukira kwa mwala. Komanso, mwamsanga wotaya katundu kumanga, pa zinthu yosungirako cholakwika angapezeke uku yafupika pafupifupi 20% pamwezi.
• Kuti tipeze yankho apamwamba, muyenera kusankha mchenga bwino. Choncho ayenera sing'anga ndi machulukitsidwe ake ndi chinyezi sayenera upambana 7%.
• Alumali moyo wa njira yomalizidwa ndi laling'ono kwambiri. Patapita maola 1-2 pambuyo kusakaniza zigawo zikuchokera ndi kale unusable, kotero kusinja simenti mtsogolo ntchito zosatheka.
