Intsebenziswano phakathi kwemixube kunye nesamente:

Umsebenzi oyintloko we-admixtures kukuphucula ukusebenza kwekhonkrithi ngokufaka izixube ezihambelanayo kwikhonkrithi, ngaloo ndlela kukhuthazwa ukuphuculwa komgangatho wokwakha kunye nokusebenza kakuhle kweeprojekthi zokwakha. Isizathu sokuba kutheni i-admixtures inokukhuthaza ukuphuculwa kweepropati ezahlukeneyo zekhonkrithi kukuba ziyakwazi ukuvelisa imiphumo efanayo kunye nekhonkrithi. Ngokwesiqhelo, iziphumo ezifanayo phakathi kwe-admixtures kunye nekhonkrithi ziyaguquguquka, ziyahambelana kwaye ziyahambelana. Kuba amacandelo aphambili kunye nobungakanani bamacandelo ahlukeneyo kwi-admixtures ahluke kakhulu, ukuguquguquka phakathi kwemixube eyahlukeneyo kunye nekhonkrithi kuya kwahluka kakhulu. I-Admixtures kunye nokulungelelaniswa okungahambi kakuhle ayinakubangela kuphela izinga lokunciphisa amanzi aphantsi kwekhonkrithi, kodwa kubangele ukuba ikhonkrithi ibekwe ngokukhawuleza, ngaloo ndlela ichaphazela ukwakhiwa okuqhelekileyo kweprojekthi. I-Admixtures enokulungelelaniswa kakuhle inokuphucula ngokufanelekileyo izinga lokunciphisa amanzi ekhonkrithi kwaye igweme ukukrazula kunye nokuqhekeka kwekhonkrithi ukuya kwinqanaba elithile. Ukuhambelana kwe-admixtures kunye nekhonkrithi kuya kuchaphazela ukusebenza kakuhle kwe-adsorption yekhonkrithi kwii-admixtures. Ukuba ukuhambelana kwe-admixtures kunye nekhonkrithi kuphantsi, ukusebenza kakuhle kwe-adsorption yekhonkrithi kwi-admixtures kuya kuba kuphantsi kakhulu, okuya kuchaphazela imiphumo eyahlukeneyo ye-admixtures yayo. Ukuhambelana kwee-admixtures kunye nekhonkrithi kuya kuchaphazela ukusebenza kakuhle kokusetyenziswa kwe-admixtures. Ukuba ukuhambelana kwe-admixtures kunye nekhonkrithi kuhluphekile, ikhonkrithi ayiyi kukwazi ukudibanisa kunye ne-admixtures, okuya kubangela inkunkuma ye-admixtures ethile.

Iingcebiso kwimigaqo yokhetho lwemixube exubeneyo yekhonkrithi:

1. Abavelisi be-concrete admixture kufuneka babe neenkonzo ezigqibeleleyo zokuthengisa kwangaphambili kunye nasemva kokuthengisa. Xa kuthengiswa admixtures eziphathekayo, abavelisi bekhonkrithi admixture kufuneka bagxininise kwizinto ezifanelekileyo, ukuseka amaxwebhu obugcisa adityanisiweyo apheleleyo ekhonkrithi kangangoko kunokwenzeka, ukubonelela ngemiyalelo ye-concrete ye-concrete, kwaye uqinisekise ukuba ukuthengiswa kwe-concrete admixtures kuqhutyelwa ngaphakathi kwendawo yenkxaso yobugcisa ekhoyo.

2. Khetha umgangatho ochanekileyo wokudibanisa. Xa ukhetha ii-admixtures zekhonkrithi ezixutyiweyo, kuyafuneka ukuba wazi kakuhle iintlobo ezichanekileyo ezisebenzayo kunye needosi ze-admixtures. Fumana i-admixtures yekhonkrithi efanelekileyo kuvavanyo oluthelekisayo, khetha i-admixtures ekumgangatho ophezulu kangangoko kunokwenzeka, kwaye unike umdlalo opheleleyo kwindima ye-concrete admixtures.

3. Khetha iskimu sokulinganisa iimitha esifanelekileyo kwi-automation yemveliso. Ukukhetha i-metering scheme efanelekileyo kwi-automation yemveliso ikwangomnye wemigaqo ebalulekileyo yokukhethwa kwee-admixtures zekhonkrithi ezixutywe.

4. Ukukhetha i-admixtures kunye neenzuzo eziphezulu zoqoqosho Ukukhethwa kwee-admixtures ezineenzuzo eziphezulu kukuhlangabezana ngcono neemfuno zokwakha kunye nemveliso yeeyunithi zokwakha. Kufuneka ihambelane nemeko yangoku yeeyunithi zokwakha, ibe neempawu ezithile zohlalutyo olubanzi, ihlangabezane neemfuno zesalathiso soqoqosho lweeyunithi zokwakha ukuya kumlinganiselo othile, kwaye ube neempawu zenzuzo yezoqoqosho. Ngoko ke, esi sikimu sokukhetha i-admixture sibonwa ngokunzulu ngamacandelo okwakha.
