Ukusetshenziswa kasimende ngalinye 1 m2 bricklaying: izinhlobo usimende ingxube kanye nezinkambiso yayo

Kusasele amashumi eminyaka futhi isitini namanje uhlala omunye zokwakha ethandwa kakhulu. Lokhu kungenxa ukuqina yayo, nobungane kwemvelo, kanye eliphezulu ezishisayo ukwahlukanisa izakhiwo. Nokho izinga odongeni akuxhomekile nje kuphela esimweni indaba, kodwa futhi ikhambi kalula yehlisele phezu kwamanzi, ukuze babe adhesion obuhle izihloko bese ugcwalisa emalungeni libhekene ukumelana kwezulu.

Ingatholakala kanjani amandla okusezingeni eliphezulu

Ukuze sifinyelele namandla okusezingeni eliphezulu yesixazululo kungaba ekutholeni kahle ivolumu kasimende, babebeka izitini ngoba kuphela Ukwakheka ikhambi elinjalo. Kuye ngalokho ukuklanywa injongo umthwalo, izinhlobo ezahlukene isixazululo isibopho lingasetshenziswa, lapho engezwa uhlobo oluthile usimende. Ngezinye izikhathi isetshenziselwa ukwakha izindonga zangaphakathi lime-usimende slurry, lapho inani isibopho kuyehla.

Ukuze kwandiswe plasticity izithako kunezelwa izinto ezahlukene. Ngezinye izikhathi ngisho imoto abavamile imele phakathi kwabo. Izingxenye ezisemqoka yilezi:

• amanzi;
• usimende;
• isihlabathi.

Ingxenye wale mithandazo izingxenye ezimbili ngokuvamile kanje: 1 kuya ku-4 Lokhu kubonisa ukuthi oyedwa imitha cubic solution kufanele kube ukusebenzisa okwesihlanu usimende. Njengoba sazi ukuthi isisindo 1 m ³ imayelana 1300 kg, ukwakheka iza ukulungiselela 260 kg kasimende.

usimende ukusetshenziswa bamba imitha square

Ngaphambi kokuqala umsebenzi, kudingeka uthole ukuthi yini ukusetshenziswa usimende ngalinye 1 m2 isitini ezakhiweni zamatshe aqoshiwe. Lesi sibalo kuzoncika ukushuba odongeni: elikhulu kangakanani, aba maningi nenani impahla edingekayo. Uma uqonde izindonga, ogama ukujiya kuyoba ingxenye yesine-isitini, le wokwakha per imitha square kuyodingeka 5 kg kasimende, kuyiqiniso, noma ikhambi uzoba uphawu M-100.

Ukusetshenziswa kasimende ngalinye 1 m2 wokwakha izitini kg uzobe ngenzasi. Umthamo usimende kuyehla kube 4 kg uma ulungiselela ebangeni isixazululo M-75. Ukuze M-50 bazodinga 2,5 kg kasimende. Isixazululo kuyoshiswa ngokuba akhiwe efanayo. Ngakho, kunesidingo sokuba imitha cubic 300 kg. Lokhu kulingana kumkhawulo 0.25 ukuze 0.3 m ³ solution ngalinye 1 m ³ ebusweni. Isilinganiso yesihlabathi usimende kuyoba kanje: 4 ukuze 1. Kuyoba ezidingakalayo ukuze kufezeke ukuqina elilungile kanye ukuhamba.

Ukusetshenziswa kasimende ngalinye 1 m2 isitini wokwakha ingashintshiwe uma ngesikhathi kuhlangana kunezelwa:

• nangemabula;
• ubumba;
• okufakiwe zokwenziwa;
• limestone kanye nezinye izingxenye.

serekhodi

Isilinganiso yesihlabathi usimende kungancipha 9 1. Lapho amvalele ukhonkolo ke ku 1 m ³ 500 kg usimende ingxube uzobe idliwe engasekho. Nge olunembile ukusebenza ngokhonkolo kungatholakala ngokufunda amazinga isimo. Nokho, ukusetshenziswa usimende ngalinye 1 m2 wokwakha izitini ingahluka uma abakhi ihlose ukuthola kwabantu, viscosity nokwesula isikhathi sinezici ezithile.

Kodwa ubuchwepheshe ayiguquki. Luhilela ukuxuba usimende nesihlabathi efomini ezomile, lapho amanzi kancane kancane wanezela izingxenyana ezincane. Ngenxa yalokho, kufanele uqiniseke ukufana okuqukethwe, okuyinto kakhulu ngeke inqamuke futhi kuyinto-nxenye. Kulokhu, bamba izothatha isikhathi eside, ukhonkolo liyokhala, futhi idizayini iyokwehluka ukuqina kanye enokwethenjelwa.

Izinhlobonhlobo grout

Manje uyazi ukusetshenziswa usimende ngalinye 1 m2 isitini ezakhiweni zamatshe aqoshiwe. Nokho, ngaphambi kokuqala umsebenzi, kubalulekile ukwazi okwengeziwe izinhlobonhlobo usimende nosimende. Izitini kungase libekwe phezu kodaka, lapho izithako kunezelwa limestone kanye nezinye izinto. Ukusetshenziswa kasimende ke uzimisele izingxenye ivolumu. Lime batch zingaphansi nezinye izixazululo empikiswaneni amandla, ngakho compounds enjalo neze isetshenziselwe ukudala dolobha izakhiwo.

Usimende nomcako mass plastic, ngakho ingasetshenziswa wokwakha izitini. Uma kuziwa ukuxuba usimende, izingxenye ezilandelayo zisetshenziselwa ekuwulungiseleleni:

• usimende;
• amanzi;
• isihlabathi.

Ukuthembeka, ukuqina kanye namandla kuzoncika sha kanye nekhwalithi usimende. Ukugeleza le ngxenye futhi olinganise yezingxenye neze ukushintsha. I njalo kunazo izinguquko banga. Ngokwesibonelo, i-izindonga ukuzisekela kuyehla, kanti yenethiwekhi kudinga ebangeni ephakeme. Ukuze uthole 1 ^m3 inhlanganisela, kufanele lisetshenziswe isamba kasimende izikhwama 8, ivolumu zazo ngamunye 50 kg.

maqondana layo isihlabathi kanje: 1 kuya ku-4 Kulokhu ukudala eyodwa imitha cubic kuyoba wokwakha kunesidingo 0.3 m ³ lobumba nasezitinini 405, ubukhulu ngayinye okuzoba 250h120h55 mm. Kulesi bamba kumele kwenziwe kwelinye isitini.

Ukwahlukanisa usimende amamiksi

Ukulinganisela isicelo kasimende ngalinye 1 m2 wokwakha izitini ziye eshiwo ngenhla. Nokho, ngaphambi kokuqala umsebenzi, kubalulekile ukwazi kabanzi, futhi izinhlobo eziyinhloko kasimende ukuhlanganiswa. Isigaba sokuqala sihlanganisa usimende-isihlabathi nosimende noma gortsovki. Ngezinye yokukhiqiza zabo indlela eyomile sisetshenziswa lapho kuhhonela rotary isetshenziswa. Izingxube okunjalo ezibizayo uma ziqhathaniswa yokufuna usimende nesihlabathi, kodwa bekhululeke kakhudlwana ngenxa esitebeleni izinga isihlabathi.

Eyesibili uhlobo - ingxube usimende ne izithasiselo rheological, okufanele kubandakanye cellulose ethers ukwandisa adhesion okuyinhloko kanye nokugcinwa amanzi. Aguqula ingxube ibe esigqulweni, Tile ingcina noma kakhonkolo. Leli qembu ezibizayo, kodwa uyakwazi ukumboza cishe yonke indawo ukusetshenziswa usimende Izingxube. iqembu Okwesithathu - eqolo, ngoba ifaka ezomile Izingxube cementitious equkethe rheological izithasiselo namandla, okwandisa ukumelana nokuhuzuka Ukubhidliza.

isiphetho

Ukusetshenziswa kasimende ngalinye 1 m2 wokwakha izitini ebheke akukashintshi njengoba kwaba njalo endabeni engenhla. Lokhu kuyiqiniso uma umkhiqizo uyoba usayizi ofanayo. Ngokuvamile, a bamba enjalo wenziwa isitini, ngakho ngeke iyangena izindleko overruns izinto zokusetshenziswa. usimende ukusetshenziswa ngayinye 1 m2 wokwakha izitini nengxenye-isitini angenqaba ncamashi 2 izikhathi.
