Indima yemixube yekhonkrithi:

Indima yezongezo zekhonkrithi iyahluka ngohlobo lwezongezo zekhonkrithi. Indima eqhelekileyo kukuphucula umbane wekhonkrithi ehambelanayo xa ukusetyenziswa kwamanzi kwi-cubic meter yekhonkrithi okanye ukusetyenziswa kwesamente akutshintshi; xa ukusetyenziswa kwe-samente kuhlala kungatshintshi okanye i-concrete slump ingatshintshi, ukusetyenziswa kwamanzi kungancitshiswa, kwaye amandla ekhonkrithi nawo aphuculwe, kwaye ukuqina kwekhonkrithi kuphuculwe; xa amandla oyilo kunye nokudilika kwekhonkrithi kuhlala kungatshintshi, ukusetyenziswa kwe-samente kunokugcinwa kwaye iindleko zingancitshiswa, njl njl. I-arhente yamandla yokuqala iphucula amandla okuqala ekhonkrithi kwaye isetyenziswa kakhulu kwiiprojekthi zokulungisa ngokukhawuleza kunye nekhonkrithi yokwakha ebusika; umnciphisi wamanzi unomphumela wokunciphisa nokuqinisa amanzi ngelixa ugcina ukuhambelana kwekhonkrithi kungatshintshi; i-ejenti yokungenisa umoya iyancipha kakhulu ukuhlukana kwamanzi okubangelwa amabhubhu awenziwe ngexesha lokuxutywa kwekhonkrithi kunye nokuphucula ukusebenza kwekhonkrithi; i-retarder inokulibazisa ixesha lokumisela ikhonkrithi, kwaye ineempembelelo zombini kunye nokunciphisa amanzi. Isetyenziswa ikakhulu kwikhonkrithi enomthamo omkhulu, ikhonkrithi eyakhiwe phantsi kweemeko zemozulu eshushu, okanye ikhonkrithi ethuthwayo kwimigama emide.

Uhlalutyo lwempembelelo yesinciphisi samanzi axubileyo ekusebenzeni kwekhonkrithi:

Iconcrete admixture water reducer ubukhulu becala yenziwe zi-surfactants. Le surfactant yeye-anionic surfactants. Eyona nto ibalulekileyo, i-ejenti yamanzi ye-alkali yekhonkrithi ayidlali indima yeekhemikhali ngesamente. Impembelelo yayo kwikhonkrithi ibonakala kakhulu kwiplastiki yekhonkrithi entsha. I-Plasticization yinto yokumanzisa, i-adsorption, i-dispersion kunye ne-lubrication effect.

I-adsorption, i-dispersion, i-lubrication kunye nemiphumo yokumanzisa kwe-admixture water reducer yenza kube lula ukuxuba ikhonkrithi ngokulinganayo kunye nomlinganiselo omncinci wamanzi, ukwenzela ukuba kuphuculwe ukusebenza kwekhonkrithi entsha. Le yimpembelelo yeplastiki ye-admixture water reducer kwi-concrete entsha.
