• I-High Dispersion Efficiency: I-PCE powder inomsebenzi ophezulu wokusasazeka, eyenza ukuhanjiswa okufanayo kweengqungquthela zesamente kunye nezinye izithako kumxube wekhonkrithi. Oku kukhokelela ekuphuculeni ukuhambelana kunye ne-homogeneity yekhonkrithi.
• Ukulawulwa kokuSetyenziswa ngokukhawuleza: I-powder ye-PCE ivumela ukulawula okuchanekileyo ngexesha lokumisela ikhonkrithi, okwenza uhlengahlengiso luhlangabezane neemfuno ezithile zeprojekthi kunye neemeko zokusingqongileyo.

2. Usetyenziso lwePCE Powder:

• I-Ready-Mix Concrete: I-PCE powder isetyenziswe ngokubanzi kwimveliso yekhonkrithi ekulungeleyo, apho inceda ukuphucula ukuhamba kunye nokumpompa komxube wekhonkrithi, okukhokelela ekwakhiweni ngokukhawuleza kunye nezakhiwo eziphezulu ezigqityiweyo.
• I-Concrete ye-Precast: Kwimveliso ye-concrete ye-precast, i-PCE powder iququzelela ukuveliswa kwamandla aphezulu, izinto eziqinileyo zekhonkrithi kunye neendawo ezigudileyo kunye nemilinganiselo echanekileyo. Ivumela ukuchithwa ngokukhawuleza kunye nokuphathwa kwamacandelo e-precast, ukunciphisa ixesha lokuvelisa kunye neendleko.
• I-Self-Consolidating Concrete (SCC): I-PCE powder iyimfuneko ekuveliseni ikhonkrithi yokudibanisa, ehamba ngokulula kwaye igcwalise i-formwork ngaphandle kwesidingo sokungcangcazela. I-SCC eyenziwe nge-PCE powder ifanelekile kuyilo oluntsonkothileyo lwezakhiwo kunye nezakhiwo ezinokuqinisa okuxinana.
• I-High-Performance Concrete: I-powder ye-PCE isetyenziswa ngokuqhelekileyo kwiifom zekhonkrithi eziphezulu zokusebenza, apho kufuneka amandla aphezulu, ukuqina, kunye nokusebenza. Ivumela ukuveliswa kwekhonkrithi eneempawu eziphuculweyo zoomatshini kunye nokuncitshiswa kokungena.
• I-Shotcrete kunye ne-Spray Concrete: I-PCE powder isetyenziswe kwi-shotcrete kunye nezicelo zekhonkrithi ezifafaziweyo, apho iphucula ukudibanisa, ukumpompa, kunye nokunamathela komxube wekhonkrithi kwi-substrate. Oku kuphumela kulungiso olusebenzayo noluhlala ixesha elide lwekhonkrithi, itonela yetonela, kunye nokuzinziswa kwethambeka.
• I-Mass Concrete: Kwiindawo ezinkulu zekhonkrithi, njengamadama, amabhuloho, kunye neziseko, i-PCE powder inceda ukunciphisa ukuchithwa kwe-thermal kunye nokunciphisa ngokunciphisa umthamo wamanzi womxube wekhonkrithi. Oku kuphucula ukusebenza kwexesha elide kunye nokuqina kwezakhiwo ezininzi zekhonkrithi.

3. Izibonelelo zePCE Powder:

• Ukuphuculwa kokuSebenza okuPhuculweyo: I-powder ye-PCE iphucula ukusebenza kunye nokuhamba komxube wekhonkrithi, okuvumela ukuba kube lula ukubeka kunye nokudibanisa ngaphandle kokuhlukana okanye ukuphuma kwegazi.
• Ukunyuka kwamandla: Ngokunciphisa umlinganiselo wamanzi ukuya kwi-samente, i-powder ye-PCE igalelo kumandla aphezulu oxinzelelo kunye nokuphucula ukuqina kwezakhiwo zekhonkrithi.
• Ukuphuculwa kokuPhuculwa kokuPhucula: I-PCE powder iphucula ukupompoza komxube wekhonkrithi, okwenza kube lula ukubeka ikhonkrithi kwiindawo ezinomngeni, ezifana nezakhiwo eziphakamileyo okanye izakhiwo eziphantsi komhlaba.
• Impembelelo yokuNcitshiswa kokusiNgqongileyo: I-PCE powder inceda ukunyusa ukusetyenziswa kwe-samente kunye namanzi kwimixube yekhonkrithi, okubangelwa ukukhutshwa kwekhabhoni ephantsi kunye nokunciphisa indawo engqongileyo ngexesha lokwakha.

I-PCE powder ngumxube wekhonkrithi oguquguqukayo kwaye osebenza kakhulu obonelela ngeenzuzo ezininzi kushishino lokwakha. Ubungakanani bawo obuncinci, amandla okunciphisa amanzi, kunye nokusebenza kakuhle kokusasazeka kwenza ukuba kube yinto efanelekileyo yoluhlu olubanzi lwezicelo, kubandakanywa ikhonkrithi ekulungeleyo, i-concrete ye-precast, i-self-consolidating concrete, i-shotcrete, kunye nekhonkrithi eninzi. Ngokubandakanya i-PCE powder kwiifom zekhonkrithi, iinjineli kunye neekontraki zinokufikelela ekusebenzeni okuphezulu, amandla, kunye nokuqina kwizakhiwo zekhonkrithi ngelixa ziphucula ukusebenza kakuhle kunye nokuzinza.
