Njani na ukungawi iqabaka eziphathekayo

ukumelana iqabaka zokwakha ubonisa indlela ndlovu ethile uyakwazi ukugcina iimpahla zazo emva imijikelo eziliqela ezilandelelanayo ukuqanda thawing. Kwimeko eziphathekayo, i-primary kubangela intshabalalo yayo xa besenza ezi nkqubo iba amanzi zikarhulumente eziqinileyo, leyo usebenzisa uxinzelelo olukhulu kwi iindonga microcracks kunye pores lo mbandela.

Kwelinye icala, ukuba lukhuni amanzi eziphathekayo enkulu akuthethi ukwandisa ngokukhululekileyo, ngoko ke uvavanyo bokuxhathisa iqabaka ngekhonkrithi kuba ombane aphezulu. Ukutshatyalaliswa luqala ngokwezahlulo elibukhali, uze ukuqhubeka umphantsi nomphezulu ekugqibeleni lihlaba.

Into ibalekisa ukutshatyalaliswa eziphathekayo sibe lomlingani ezahlukeneyo yokwanda thermal eziqalelo enza izinto zokwakha. Oku kudala uxinzelelo olongezelelweyo.

ukumelana iqabaka ikhonkrithi ulinganiswa ngeendlela abalawula ukuqanda thawing inkqubo. Izalathi si zokunikwa parameters zovavanyo zixhomekeke zinto zilandelayo: ngqele, amaxesha umjikelo, ubukhulu lovavanyo isampulu, indlela saturation amanzi. Umzekelo, inkqubo eziphathekayo ukuqhekezwa kwenzeka ngokukhawuleza ukuba imveliso yingqele kwi amaqondo obushushu asezantsi kunokwenzeka izisombululo yetyuwa.

ukumelana Neqabaka le njengekonkile bavandlakanywa phambi kokuba mzuzu xa kukho inani elithile imijikelo phindo akayi ukunciphisa ubunzima isampuli-5 ekhulwini yaye ayiyi kunciphisa amandla alo ngama-25 ekhulwini. Oko kukuthi inani iinkqubo bema izinto zokwakha imisela uphawu wayo. Degree qabaka kwakhona wabelwa kuxhomekeke yintoni ndawo aya kusebenza eziphathekayo.

UFrost eziphathekayo na isakhiwo okhethekileyo. Character porosity kuthintela ice volume ukwenza uxinzelelo kakhulu kwaye ukucola inkqubo kukwaphulwa.

Luvukelo iqabaka ikhonkrithi ixhomekeke kwinani macropores, ekubeni amanzi pores omhle iqhwa nokuba amaqondo obushushu asezantsi kunokwenzeka, ngoko singadali ntshikilelo olongezelelweyo. Ngenxa yoko, kuchatshazelwa ngemvelo, imilo kunye umthamo pores ezinkulu.

ukumelana iqabaka ikhonkrithi nokuba ingaphuculwa ngezi ndlela zilandelayo:

• Ukuncitshiswa pores ezinkulu ukwandisa lexinene eziphathekayo.
• Ukudalwa umoya ezongezelelweyo iyayondela ngaphakathi ngekhonkrithi ngokwazisa kudla ezithile. Ukuba umthamo kwezi pores ziya kuba ikota amanzi engumkhenkce, akasayi kuzaliswa ngexesha saturation yesiqhelo. Kwisithuba athontsize ephuma amanzi unfrozen, ice-wonke, kwaye ke xi buthathaka.

Umthamo yangaphakathi komoya kwi concrete iqabaka-resistant kufuneka ibe phakathi amane ekhulwini ezintandathu. Isixa womoya kuxhomekeke kungekuphela ukusetyenziswa zesamente kunye namanzi, kodwa kwakhona ukusuka aggregate irhabaxa. Umthamo emoyeni pores angaphakathi eziphathekayo inyuswe xa ukwandisa ukuhamba kwamanzi kunye nesamente, namaqhezu ubukhulu aggregate, phezu koko, lincitshiswe.
