Indima yezingxube zekhonkrithi:

Indima yezithako zekhonkrithi iyahlukahluka ngohlobo lwezithako zekhonkrithi. Indima evamile iwukuba ngcono uketshezi lukakhonkolo oluhambisanayo lapho ukusetshenziswa kwamanzi nge-cubic meter ngayinye kakhonkolo noma ukusetshenziswa kukasimende kungashintshi; lapho ukusetshenziswa kukasimende kuhlala kungashintshiwe noma ukwehla kukakhonkolo kungashintshile, ukusetshenziswa kwamanzi kungancishiswa, futhi amandla okhonkolo nawo athuthukisiwe, futhi ukuqina kokhonkolo kuyathuthukiswa; lapho amandla okuklama kanye nokuwa kwekhonkrithi kuhlala kungashintshiwe, ukusetshenziswa kukasimende kungasindiswa futhi izindleko zingancishiswa, njll. I-ejenti yamandla yokuqala ithuthukisa amandla okuqala kakhonkolo futhi isetshenziselwa kakhulu amaphrojekthi okulungisa izimo eziphuthumayo kanye nokhonkolo wokwakha ebusika; isinciphisi samanzi sinomphumela wokunciphisa nokuqinisa amanzi ngenkathi kugcinwa ukuhambisana kwekhonkrithi kungashintshiwe; i-ejenti yokungenisa umoya ikakhulukazi inciphisa ukuhlukaniswa kwamanzi okubangelwa ama-bubbles akhiqizwa ngesikhathi sokuxuba ukhonkolo futhi ithuthukise ukusebenza kokhonkolo; i-retarder ingabambezela isikhathi sokusetha ukhonkolo, futhi inemiphumela yokubuyisela emuva kanye neyokunciphisa amanzi. Isetshenziselwa ikakhulukazi ukhonkolo wevolumu enkulu, ukhonkolo owakhiwe ngaphansi kwezimo zezulu ezishisayo, noma ukhonkolo othuthwa amabanga amade.

Ukuhlaziywa komthelela we-admixture water reducer ekusebenzeni okukhonkolo:

I-concrete admixture water reducer yakhiwa ikakhulukazi ama-surfactants. Le surfactant ingeyama-anionic surfactants. Empeleni, i-ejenti yamanzi e-alkali kakhonkolo ayidlali indima yamakhemikhali ngosimende. Umthelela wayo kukhonkolo ubonakala ngokuyinhloko ku-plasticization kakhonkolo omusha. I-Plasticization iwumphumela wokumanzisa, wokukhangisa, wokuhlakazeka kanye nokugcoba.

I-adsorption, dispersion, lubrication kanye nemiphumela yokumanzisa ye-admixture water reducer yenza kube lula ukuxuba ukhonkolo ngokulinganayo ngamanzi amancane kuphela, ukuze kuthuthukiswe ukusebenza kokhonkolo okusha. Lona umphumela we-plasticization we-admixture water reducer kukhonkolo entsha.
