Izithasiselo zikakhonkolo zingamakhemikhali nezinto ezihlanganiswa kusimende ukuze kuguqulwe ukusebenza kwawo. Izithasiselo zinikeza inzuzo ethile yomsebenzi othile. Izithasiselo eziwuketshezi ezisetshenziswa ngesikhathi sokugaya usimende zithuthukisa amandla kasimende. Amabhondi ahlanganisayo anokhonkolo ahlanganisayo ahlanganisayo ukhonkolo wakudala kuya kwemisha emisebenzini yangaphakathi nangaphandle efana nokufaka udonga kanye nokufaka izulu kabusha. Izithasiselo zombala zinikeza ukhonkolo ukubukeka kwesitayela. Noma ngabe yimuphi umsebenzi, izithasiselo zikakhonkolo zisiza ukuthi wenziwe.

Ukhonkolo wesimo sezulu esibandayo unempahla ephakeme kunokhonkolo obekwe esimweni sezulu esishisayo. Nokho, emazingeni okushisa aphansi, ukhonkolo uyabeka futhi athole amandla kancane kancane ngoba usimende awuniki amanzi ngokushesha. Isikhathi sokusetha sinyuswa cishe ingxenye eyodwa kwezintathu ekuncipheni ngakunye okungu-10 kuzinga lokushisa likakhonkolo kuze kufike ku-40 degrees Fahrenheit. Ukusheshisa izixube kungasiza ukususa le miphumela yamazinga okushisa aphansi ekumisweni nasekuzuzeni amandla. Kufanele bahlangabezane nezimfuneko ze-ASTM C 494, Ukucaciswa Okujwayelekile kwe-Chemical Admixtures for Concrete.

I-Jufu inikeza izithasiselo zikakhonkolo zesimo sezulu esibandayo kanye nezithasiselo zikakhonkolo zokuvimbela amanzi, ezingasetshenziswa kabanzi Ekwakhiweni.

Yiziphi izinzuzo zekhonkrithi ehlanganisiwe emihle

1. Njengoba izinto ezinjalo zinokubumbana okuhle futhi zizinzile ngesikhathi sokwakhiwa, ukusebenza kahle kokukhiqiza kuthuthukiswa kakhulu. Okubalulekile ukuthi ungadlidlizi ohlelweni lokukhiqiza, okunciphisa isikhathi sokuthulula kanye nokuqina komsebenzi, futhi kunciphisa izindleko zabasebenzi.

2. Njengoba kushiwo ngaphambili, ngenxa yokuthi asikho isidingo sokudlidliza, akukho msindo, futhi izandla zabantu zingakhululeka, okuthuthukisa kakhulu ukuphepha komsebenzi futhi kuthuthukise isimo sokusebenza.

3. Ngokombono wekhwalithi yokwakha, ngeke kube namabhamuza endaweni yokwakha lapho usebenzisa le nto, ingasaphathwa eyokulungisa. Ngesikhathi esifanayo, izinga layo lenkululeko liphezulu kakhulu, ngisho nezinye izimo eziyinkimbinkimbi kakhulu noma izakhiwo ezinokuqiniswa okuminyene zingathululwa kalula.

Yiziphi izinyathelo zokuphepha zokuxuba ukhonkolo:

1. Umsingathi wokuxuba ofakwe ngaphansi kwemibandela yelebula ehlukene uhlukile, hhayi lokho kuphela, kodwa futhi kuncike ohlotsheni lwezinto ezithile, ukuze ukhethe izithako ezifanele kanye nemishini.

2. Ukusetshenziswa kwesiteshi esisodwa noma ezimbili kuncike emthwalweni othile wokusebenza. Uma inani elikhulu lekhonkrithi lidinga ukuthululwa ngesikhathi esisodwa futhi izidingo zekhwalithi yalo ziphakeme kakhulu, kungcono ukusebenzisa amaqoqo amabili ezitshalo ezincane zokuxuba.
