Yintoni i-Admixture kuLwakhiwo?

Ekwakhiweni, i-admixture ibhekiselele kwizinto ezingaphandle kwamanzi, i-aggregates, izinto ze-cementitious, okanye iifayibha ezongeziweyo kwikhonkrithi, udaka, okanye i-grout ukuguqula iipropati zayo okanye ukuphucula ukusebenza kwayo. I-Admixtures isetyenziselwa ukuguqula ikhonkrithi entsha okanye eqinile ngeendlela ezahlukeneyo, ukuvumela ulawulo olukhulu kwiipropati zayo kunye nokuphucula ukusebenza kwayo, ukuqina, amandla kunye nezinye iimpawu. Nazi ezinye iindidi eziqhelekileyo zemixube esetyenziswa kulwakhiwo:

1. Imixube yokunciphisa amanzi:

• I-admixtures yokunciphisa amanzi, eyaziwa ngokuba yi-plasticizers okanye i-superplasticizers, izongezo ezinciphisa umthamo wamanzi ofunekayo ukufezekisa umsebenzi ofunekayo wekhonkrithi ngaphandle kokuncama amandla okanye ukuqina. Baphucula ukuhamba kunye nokusebenza kwemixube yekhonkrithi, okwenza kube lula ukuyibeka nokugqiba.

2. Ukurhoxiswa kweMixube:

• I-admixtures yokubuyiswa isetyenziselwa ukulibazisa ixesha lokumisela ikhonkrithi, i-mortar, okanye i-grout, evumela ukusebenza okwandisiweyo kunye nexesha lokubeka. Ziluncedo ngokukhethekileyo kwiimeko zemozulu ezishushu okanye kwiiprojekthi ezinkulu apho ukulibaziseka kwezothutho, ukubekwa, okanye ukugqiba kulindeleke.

3. Ukukhawulezisa imixube:

• I-accelerating admixtures zizongezo ezikhawulezisa ukusetwa kunye nophuhliso lwangoko lwamandla ekhonkrithi, i-mortar, okanye i-grout, evumela inkqubela phambili yokwakha ngokukhawuleza kunye nokususwa kwangoko kwe-formwork. Ngokuqhelekileyo zisetyenziswa kwiimeko ezibandayo zemozulu okanye xa kufuneka ukuzuza amandla ngokukhawuleza.

4. Imixube yokungenisa umoya:

• Imixube yokungenisa umoya zizinto ezongeziweyo ezizisa amaqamza omoya amancinci kwikhonkrithi okanye udaka, iphucula ukuxhathisa kwayo kwimijikelo yokunyibilika komkhenkce, ukukala, kunye nokuqhawuka. Baphucula ukusebenza kunye nokuqina kwekhonkrithi kwiimeko zemozulu ezinzima kunye nokunciphisa umngcipheko womonakalo ukusuka ekuguquguqukeni kweqondo lokushisa.

5. Ukurhoxiswa kweMixube yokuNgenisa umoya:

• Ukubuyiswa kwe-admixtures ye-air-entraining idibanisa iipropati ze-retarding kunye ne-air-entraining admixtures, ukulibazisa ixesha lokubeka ikhonkrithi ngelixa likwafaka umoya wokuphucula ukuxhathisa ukunyibilika kwayo. Ngokuqhelekileyo zisetyenziswa kwiindawo ezibandayo okanye kwikhonkrithi evezwe kumjikelo womkhenkce kunye nokunyibilika.

6. I-Corrosion-Inhibiting Admixtures:

• I-Corrosion-inhibiting admixtures izongezo ezinceda ukukhusela ukuqiniswa kwentsimbi efakwe kwikhonkrithi kwi-corrosion ebangelwa ukuvezwa kokufuma, i-chlorides, okanye ezinye ii-agent ezindlongo. Bandisa ubomi benkonzo yezakhiwo zekhonkrithi kunye nokunciphisa iindleko zokugcina nokulungiswa.

7. Imixube eNcitshiswayo yokuNcitshiswa:

• I-Shrinkage-reduction admixtures izongezo ezinciphisa ukomisa i-shrinkage kwikhonkrithi, i-mortar, okanye i-grout, ukunciphisa umngcipheko wokuqhaqha kunye nokuphucula ukuqina kwexesha elide. Ziluncedo ngakumbi kwiindawo ezinkulu zekhonkrithi, izinto zekhonkrithi zangaphambili, kunye nemixube yekhonkrithi esebenza kakhulu.

8. Imixube yokuthintela amanzi:

• I-admixtures yokuthintela amanzi izongezo eziphucula ukunganyanzeki kwekhonkrithi, i-mortar, okanye i-grout, ukunciphisa ukungena kwamanzi kunye nokuthintela imiba enxulumene nokufuma efana ne-efflorescence, ukufuma kunye nokugqwala. Ngokuqhelekileyo zisetyenziswa kwizakhiwo ezingaphantsi komgangatho, amagumbi angaphantsi, amatonela, kunye nezakhiwo zokugcina amanzi.

Ngamafutshane, ii-admixtures zidlala indima ebalulekileyo kwitekhnoloji yekhonkrithi yale mihla, evumela ukuguquguquka okukhulu, ukusebenza kakuhle, kunye nokusebenza kwiiprojekthi zokwakha. Ngokukhetha kunye nokubandakanya i-admixtures efanelekileyo kwimixube yekhonkrithi, abakhi kunye neenjineli banokufikelela kwiimfuno ezithile zoyilo, ukuphucula iinkqubo zokwakha, kunye nokunyusa ukuqina kunye nokuzinza kwezakhiwo eziphathekayo.
