M350 Ukhonkolo: izici eziyisisekelo futhi isicelo

M350 Ukhonkolo - isinikeza ukwaziswa ukwakhiwa, okuvumela ukuba enze izakhiwo ezibalulekile kakhulu ukufeza izinhloso ezahlukene kanye izakhi ezahlukene prefabricated. Ngemva sokwelapha yayo ukwakheka kuyahluka amazinga aphezulu nokuqinisela, onezici ezinhle, amandla ikakhulukazi compressive. Ngo ukwakhiwa zanamuhla isigaba ukhonkolo B25 ungumholi kokubili ngokoMthetho udumo, njengoba yokuthengisa.

impahla Isicelo

M350 ekilasini ukhonkolo B25 isetshenziswa cishe zonke izinhlobo ukwakhiwa. Kulo kukhona wenza slabs, nezisekelo eziqinile, izindonga, nemishayo, nemibundu, amakholomu, izakhiwo zikakhonkolo nezinye izakhi isakhi yokuhlala, izimboni kanye ehhovisi izakhiwo, imithwalo esindayo. Futhi lokhu nosimende ukwenza airfield umgwaqo amapuleti eziqhutshwa ngaphansi Isisindo esikhulu.

Sibheka kabanzi izici emimoya ngeziningi zezinto zokwakha.

izici

Cabanga iqoqo elithile amandla e kokucindezelwa. It is kulinganiswa ngo MPA, kunqunywa B25 ekilasini (1 imitha cubic. Material ngaphandle kokuyekethisa ubuqotho namandla okuzabalaza ingcindezi 25 MPA). B25 amandla Owengeziwe ibangelwa khona e ingxube kasimende ngaphezulu. Ngaphezu amandla lokhu brand kasimende unezinye, izici ezibalulekile ngokulinganayo: ukumelana nesithwathwa, ukumelana amanzi ukuhamba.

ukuhamba

Lesi isilinganiso siyahlukahluka abakuzuzile P2 ukuze P4. Kodwa ezingeni amandla zingandiswa kumanani ephakeme lapho ukhonkolo is kulekelelwa izithasiselo ekhethekile - plasticizers.

impermeability

B25 Ukhonkolo owenza inkomba permeability - W8. Lokhu ipharamitha kubonisa ukuthi into akakwazi ukuba adabule umswakama ngisho noma enza kube ngaphansi kwengcindezi enkulu. Ngenxa yalesi grade ukhonkolo M350 ingasetshenziswa ezindaweni ithebula komhlaba eliphezulu.

isithwathwa

Inkomba frost ukumelana F200 kubonisa ukuthi le nto akaphelelwa impahla yayo futhi ubuqotho kwesakhiwo ngemva ezingamakhulu amabili iqhwa-ncibilika imijikelezo. aphathekako afana ingasetshenziswa ezindaweni nokhahlo.

umthamo isisindo

Kulolu hlu ku M350 ukhonkolo 1800-2500 kg / m³. Nokho, ngokuvamile i-isisindo ivolumu (ukuminyana) we amabanga impahla kusuka 2200 kuya 2400 kg / m³.

izingxenye ezisemqoka

M350 Ukhonkolo ngokuvamile akhiqizwa ngendlela ingxube usimende, amanzi, isihlabathi futhi yamathebhu okuqinile, ezifana amatshe noma afahlazekile itshe egwadle. Ukuze uthuthukise properties kwezingxenye ngezithako zawo izithasiselo admixed futhi plasticizers, kanjalo nokwandisa nobubanzi balolu grade ngokhonkolo

Ukuze kukhiqizwe isixazululo B25 grade esetshenziswa:

• usimende;
• isihlabathi;
• amatshe;
• amanzi;
• plasticizers;
• emelana nokubanda enhlanzini yasezindaweni izithasiselo.

Kufanele kuqashelwe ukuthi izingxenye esetshenziswa ukulungiselela isixazululo angase abe umehluko izici kanye nemingcele lwabo, okungukuthi, ubukhulu kuyizinhlayiyana, amandla, ubumsulwa, umswakama.

Ngokwesibonelo, njengoba yamathebhu kungaba:

• isihlabathi okuncane, ingxenyenamba esikhulu noma phakathi;
• amatshe (limestone noma egwadle);
• ochotshoziwe itshe nokuhlolwa.

Futhi uzinake ukuthi B25 ukhonkolo has iphesenti ephakeme kasimende okuqukethwe, okuyinto enomthelela a solidification ngokwanele okusheshayo.

ngezabelo

Ngokuba ukulungiswa 1 m ³ of indaba uzodinga:

• 400 kg kuqinise M400 noma M500;
• 752 kg isihlabathi, wahlanza kusuka ukungcola;
• 175 amalitha amanzi;
• 1 m yamathebhu okuqinile (isb, amatshe).

Ukuze uthole eliphezulu futhi iqine M350 ukhonkolo, kubalulekile hhayi kuphela ukulandela ngokucophelela inani Ukwakheka ngalinye 1 m ^3, kodwa uhlanganise kahle zonke izingxenye ukuthi mass okuholela kwaba eyohlobo. Ukwakheka Kahle okuxubile iyehlisa amandla material.

Ukulungiselela yesixazululo

• Okokuqala, udinga mixer engeza izithako ezomile (usimende nesihlabathi) uhlanganise kahle.
• Engeza amanzi. Kulesigaba isixazululo elachithwa ibe plasticizer noma ezinye okufakiwe.
• Kungezwe ofakwe amanzi imfucumfucu noma amatshe.
• Beza neqhinga okuxubile kahle.

Ukhonkolo M350: Intengo

Abakhiqizi ukusetha intengo zabo ngenxa impahla ngokungeza up zonke izindleko, iningi olungena on imfucumfucu kanye usimende. Ukuze inzuzo yiyona margin okudayisa ngenhla izindleko. Yingakho lonke nomkhiqizi uphendulela "siqu" izindleko oyinhloko okuyinto incike izindleko impahla eluhlaza.

Umthuthukisi ngamunye ekhetha ukuthi ubani ukuthenga M350 ukhonkolo. Izindleko isilinganiso le nto nge egcwele amatshe-non-ukulethwa kuzosuka 3 000 k. 1 imitha cubic inhlanganisela, nge amatshe egwadle - ruble 3 700.

Uma kwethulwa emelana nokubanda enhlanzini yasezindaweni izithasiselo, intengo uzoqala ngo ruble 4000. Futhi izindleko ukhonkolo kuthonywa ukumelana layo amanzi - kuka sibalo ngenhla, intengo kuyabiza. Ngakho, singaphetha ngokuthi izindleko impahla incike nomkhiqizi futhi izindleko yokufuna izingxenye oluyinhlanganisela.
