Ukusetha-i-accelerator-calcium kwakha

I-calcium yakha ngempela ingasebenza njenge-accelerator ngokhonkolo. Nakhu ukuthi kusebenza kanjani:

Ukusetha Mechanism Ukusheshisa:

1. Inqubo ye-Hydration: Lapho i-calcium yasungulwa ku-conkcrete mixtures, iyancibilika emanzini bese ikhipha i-calcium ion (CA ^ 2 +) nokwakha i-ion (HCOO ^ - -).
2. Ukukhuthaza ukwakheka kwe-CSH: I-calcium ion (ca ^ 2 +) ekhishwe kusuka ku-calcium ekhishwe usabela ngezinsimbi zokulingisa usimende, ukusheshisa ukwakheka kwe-calcium siliate hydrate (Csh) Gel. Le Csh Gel iyi-tinder eyinhloko ngokhonkolo, ebhekele amandla nokuqina kwayo.
3. Isikhathi sokusetha ngokushesha: Ukwakheka okusheshayo kwe-Csh Gel kuphumela ngesikhathi esisheshayo sengxube ekhonkolo. Lokhu kuvumela ukuqeda okusheshayo nokuqedwa kwamafomu, ukusheshisa inqubo yokwakha ebanzi.

Izinzuzo zokusebenzisa i-calcium yakha njenge-accelerator yokusetha:

1. Amandla okuqala athuthukisiwe: Amandla okuqala kakhonkolo ayathuthukiswa ngenxa yenqubo esheshayo ye-hydration evuselelwa yi-calcium yakha. Lokhu kungazuzisa ikakhulukazi ezimeni zezulu ezibandayo lapho izikhathi zokubeka khona kancane zigcinwa khona.
2. Isikhathi Sokukhiwa Kwehlisiwe: Ngokusheshisa isikhathi sokusetha ukhonkolo, i-calcium formate kusiza ukunciphisa isikhathi sokwakha futhi kuvumela ukuqedwa kwephrojekthi esheshayo.
3. Ukusebenza okuthuthukile: Ukusebenza kwe-calcium kungathuthukisa ukusebenziseka kokhonkolo, okwenza kube lula ukuphatha nokubeka, ikakhulukazi ezimweni lapho kudingeka khona ukusetha okusheshayo.

Isicelo kukhonkolo:

• I-calcium yakha ngokujwayelekile ingezwe ekuxubeni ukhonkolo endaweni ye-dosage esukela ku-0,1% kuya ku-2% ngesisindo sesikhathi sokwenza usimende, ngokuya ngezidingo zokusebenza ezifiselekayo.
• Imvamisa isetshenziswa ekukhiqizweni kokhonkolo okuqala, izinhlelo ze-shotcrete, kanye nemiklamo yokwakha lapho kudingeka khona ukusetha okusheshayo.

Ukucatshangelwa:

• Ngenkathi i-calcium iqala ukusheshisa isikhathi sokusetha ukhonkolo, kubalulekile ukuze ucabangele ngokucophelela amanani emithambeka kanye nokuhambisana namanye ama-admixtures ukugwema imiphumela emibi empahleni ukhonkolo.
• Izindlela zokulawula ezisezingeni kufanele zenziwe ukuze kuqinisekiswe ukuthi ukhonkolo osheshisiwe ugcina amandla afiselekayo, ukuqina, kanye nezimpawu zokusebenza.

I-calcium yakha isebenza njenge-accelerator esebenzayo yokusetha ukhonkolo, ithuthukisa i-hydration esheshayo kanye nokuthuthukiswa kwamandla kusenesikhathi. Ukusetshenziswa kwayo kungasiza ukusheshisa amashejuli wokwakha futhi kuthuthukise ukuzokwenza, ikakhulukazi ezimweni zezulu ezibandayo noma kumaphrojekthi abucayi besikhathi. Kodwa-ke, ukucatshangelwa okufanelekile kanye nokubhekwana okuhambelana kubalulekile ekufezekiseni izakhiwo zokhonkolo ezifiselekayo ngenkathi usebenzisa i-calcium yakha njenge-accelerator.
