Isisindo ezithile ukhonkolo incike uhlobo yayo

Kuvele itshe yokufakelwa okuyinto kuveza ngokuxuba amanzi, usimende kanye lokubolekwa (amatshe, isihlabathi noma amatshe), futhi phambili solidification yabo ibizwa ukhonkolo.

Ngenxa izinto zokwakha zaqala ukusetshenziswa endulo ukwakheka ukhonkolo lapho ke kwahluka ngokuphawulekayo kusukela manje. Kwake kwaba nesikhathi lapho emiswa ngesikhathi ukusetshenziswa, kodwa ngekhulu XIX yasungulwa binders entsha wokubacindezela, ezifana, udumo isibonelo, Portland usimende, ukhonkolo kabusha yazuza ukwakhiwa. Ngo-60-yalolucwaningo of XIX leminyaka. It sashintsha usimende yokukhiqiza ubuchwepheshe, amandla brand anda futhi lalisetshenziselwa njengendlela yokuhlanganisa esiyinhloko ukhonkolo. Okwamanje lo mkhiqizo - yezinto ezibaluleke kakhulu ezisetshenziswa cishe kuzo zonke izindawo ukwakhiwa yesimanje.

ukuqashelwa okunjalo, wathola sibonga izici ezilandelayo:

• ezihlukahlukene izakhiwo atholwe kwakubangelwa ukuhlukahluka izinga ukusetshenziswa kwezinto eziphinde zisebenziseke itshe futhi binders futhi ezihlukahlukene physicochemical futhi yenqubo yokugaya;
• lula ukusebenza mix ukhonkolo, okuyinto has a nezimo ngokuphelele okusezingeni eliphezulu futhi ivumela okwenza ezihlukahlukene bobunjwa nobukhulu okuhlala, okusezingeni eliphezulu izakhiwo esakhiweni;
• kungenzeka ngokugcwele imishini inqubo umsebenzi ngokhonkolo;
• umnotho, nevolumu yayo by 80-90% siqukethe itshe aqoqa ukukhiqizwa lendawo.

Ukukhiqizwa high mix ukhonkolo kungenzeka kuphela ulwazi ubuchwepheshe, ngokukhetha izinto amakhono izinga elithile kanye nekhono ukubala isilinganiso zabo, ukuthola izindlela isitayela, izimvu zamanzi kanye izindlela ukuxuba.

Ukuze ukwakhiwa kwezakhiwo ubunjiniyela ezihlukahlukene usebenzisa izinhlobo ezahlukene ukhonkolo (e kuncike isicelo). Kukhona izici ezibalulekile eziningana, okuyizinto impahla oluthathwa: isisindo ethile eziphathekako amandla awo, uhlobo isibopho, inhloso kanye frost. Ukwahlukaniswa main senziwa isisindo ivolumu. Ngakho kuye, Concretes kakhulu ukukhanya, ukukhanya, esindayo futhi extra esindayo.

1. Emfanekisweni wokuqala - nabaningi aphakathi nendawo kanye elincane amaseli mayelana 1-1.5 mm ubukhulu, ngakho babizwa nangokuthi yeselula. Isisindo ezithile ivolumu obuphathekayo 1 imitha cubic imayelana 500 kg. Ngokuvamile, lolu hlobo isetshenziswa njengoba ukushisa-ekuvikeleni ungqimba.

2. Khanyisa. Lolu hlobo kuhlanganisa labo okuyiwona njengoba isimeli sebenzisa izinto ezilula engasindi - enwetshiwe ubumba, tuff, rakushnik, noma okunye awuyikusebenza fillers, namanxusa yesivini kunezelwa -. Ukhonkolo, ukhonkolo evundile nabanye I isabelo ivolumu aphathekako imitha cubic - 500-1800 kg. Ingxenye esemqoka ngezithako zawo ithatha isihlabathi - kuze kufinyelele 600 kg. Okubalulekile okunjalo ngokuvamile esetshenziselwa ukukhiqizwa amabhlogo wokwakha.

3. Njengengxenye ukhonkolo ezisindayo zibalulekile lokubolekwa krupnofraktsionnye esindayo - amatshe olwembiza. Omunye imitha cubic of isisindo saso singamakhilogremu cishe 1800-2500 kg. Le screen sikhombisa 1150-1300 kg amatshe noma itshe ochotshoziwe, isihlabathi 600-750 kg, 250-450 kg kasimende 150-200 amalitha amanzi. ukhonkolo Heavy a classic bese isetshenziswa ezindaweni eziningi ukwakhiwa.

4. Concretes Ikakhulukazi esindayo yakhiwa barite, magnetite, kuthi nezinye izinhlobo ezithile Scrap Metal. I ethize isisindo ukhonkolo ivolumu 1 imitha cubic kungenzeka kusuka 2500 kuya ku-3000 kg. Isakhi esiyinhloko iningi isisindo salo sikhulu aggregate indawo. Lolu hlobo ukhonkolo isetshenziswa ngokuyinhloko womshini izakhiwo okuvikela ukuze AEC.

Ukubala imitha cubic ngokhonkolo, akufanele sikhohlwe ukuthi izingxenye zalo angase abe ezahlukene gravity ethize. Ngokwesibonelo, encane kakhulu uma kuqhathaniswa aggregate indawo nzima nemigodi isihlabathi kulula ukudlula emfuleni.
