I-Superplasticizer ibhekisa kwimeko egcina ukudilika kwekhonkrithi ngokusisiseko kufana,

Imixube enokunciphisa kakhulu ubungakanani bamanzi asetyenziselwa ukuxuba.Isinciphisi saManzi esiSebenza ngokuPhakamileyo ngumbono omtsha ocetywayo emva kombono wekonkrithi yokusebenza okuphezulu.Okwangoku, ayikachazwa ngokucacileyo.Ngokuqhelekileyo ibhekiselele kwimixube ekhonkrithi enezinga eliphezulu lokunciphisa amanzi kunye nokusebenza kokugcinwa kwe-slump enokungenisa umoya.Nangona kunjalo, ngokuqonda kunye nokusetyenziswa kwe-polycarboxylic acid kunye nezinye i-carboxylic acid superplasticizers kwintsimi yekhonkrithi yamazwe ngamazwe kwiminyaka yakutshanje, olu hlobo lwe-superplasticizer lunazo ezi mpawu zilandelayo.

(1) Umxholo ophantsi kunye nezinga eliphezulu lokunciphisa amanzi (umxholo udla ngokuba ngu-0.05% -0.5% we-binder content, kwaye izinga lokunciphisa amanzi lingafikelela kwi-35% -50%, okanye nangaphezulu);

(2) Akukho ulwahlulo, akukho ukuphuma kwegazi, ukusebenza kokugcina i-concrete slump kungcono, kunokukwenza ngaphakathi kwe-120min ngokusisiseko akukho lahleko;

(3) inokulungiselela ukomelela okuphezulu kakhulu kunye nekhonkrithi ehlala ixesha elide;

(4) Ukuhambelana kakuhle nesamente, i-admixture kunye nezinye izixube;

(5) Inokunciphisa ngokufanelekileyo ukunyuka kobushushu be-adiabatic ekuqaleni kwekhonkrithi, ekulungele ngakumbi kwikhonkrithi enkulu;(6) Inkululeko enkulu kwisakhiwo semolekyuli, amandla amakhulu okuphumeza ukusebenza okuphezulu kwe-arhente yokunciphisa amanzi;

(7) Ngenxa yokuba i-synthesis ingasebenzisi i-formaldehyde kunye nezinye izinto ezingcolisa indalo, kunenzuzo kuphuhliso oluzinzileyo lweshishini lokwakha;(8) Inika isiqinisekiso sobugcisa sokukhuthaza ukusetyenziswa kwenkunkuma yemizi-mveliso efana ne-fly ash, i-slag kunye ne-steel slag.

Kuya kubonakala ukuba uchungechunge lwe-polycarboxylic acid ye-superplasticizer yokusebenza ephezulu kufuneka ihlangabezane neemfuno zekonkrithi yenkulungwane yama-21 ephezulu kakhulu.
