Iimpawu ze-arhente yokunciphisa amanzi zichaphazela ngokuthe ngqo ukusebenza kwe-shrinkage yekhonkrithi. Ngaphantsi kwe-concrete ye-concrete efanayo, izinga le-shrinkage yekhonkrithi kunye ne-agent yokunciphisa amanzi malunga ne-35% ephezulu kunekhonkrithi ngaphandle kwe-agent yokunciphisa amanzi. Ngoko ke, iintanda zekhonkrithi zinokwenzeka kakhulu. Nasi isizathu:
1. Umphumo wokunciphisa amanzi uxhomekeke kakhulu kwizinto eziphathekayo eziphathekayo kunye nomxube wokuxuba.
Umlinganiselo wokunciphisa amanzi wekhonkrithi yinkcazo engqongqo kakhulu, kodwa ihlala ibangela ukungaqondi kakuhle. Kwizihlandlo ezininzi ezahlukeneyo, abantu bahlala besebenzisa izinga lokunciphisa amanzi ukuvakalisa umphumo wokunciphisa amanzi kwimveliso.
Kwinqanaba eliphantsi, ukuthatha i-polycarboxylate i-agent yokunciphisa amanzi njengomzekelo, ibonakaliswe ukuba izinga layo lokunciphisa amanzi likhulu kakhulu kunezinye iintlobo zokunciphisa amanzi, kwaye inomphumela ongcono wokunciphisa amanzi. Nangona kunjalo, kufuneka kuqatshelwe ukuba xa kuthelekiswa namanye ama-agent okunciphisa amanzi, umphumo wokunciphisa amanzi we-polycarboxylate yokunciphisa amanzi ichaphazeleka ngakumbi kwiimeko zokuvavanya.
Phakathi kwezinto eziphembelela impembelelo yeplastiki ye-polycarboxylate superplasticizer, isantya sesanti kunye nokuhlelwa kwamasuntswana e-aggregates kwikhonkrithi nako kunempembelelo enkulu. Xa kuthelekiswa namanye ama-agent aphezulu okunciphisa amanzi afana ne-naphthalene series, i-plasticizing effect ye-polycarboxylate yokunciphisa amanzi ichaphazeleka kakhulu ngumxholo wodaka we-aggregates emihle.
2. Umphumo wokunciphisa amanzi uxhomekeke kakhulu kwi-dosage ye-agent yokunciphisa amanzi.
Ngokubanzi, njengoko i-dosage ye-ejenti yokunciphisa amanzi inyuka, izinga lokunciphisa amanzi lekhonkrithi nalo liyenyuka, ngakumbi kwi-polycarboxylic acid-based based-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-agent-dosa
Nangona kunjalo, kukho imida kwizicelo ezisebenzayo. Oko kukuthi, emva kokuba idosi ethile ifikelelwe, umphumo wokunciphisa amanzi "uyancipha" njengoko umthamo unyuka. Oku kungenxa yokuba ngeli xesha umxube wekhonkrithi uba lukhuni, ikhonkrithi inengxaki yokopha kakhulu, kwaye uMthetho wokudilika awusakwazi ukubuchaza ubumanzi bawo.
3. Ukusebenza komxube wekhonkrithi olungiselelwe uvakalelwa kakhulu ekusebenziseni amanzi.
Iimpawu zokusebenza zemixube yekhonkrithi zidla ngokubonakaliswa kwimiba efana nokugcinwa kwamanzi, ukuhambelana, kunye nolwelo. Ikhonkrithi elungiselelwe kusetyenziswa iipolycarboxylic acid-based superplasticizers ayisoloko ihlangabezana ngokupheleleyo neemfuno zokusetyenziswa. Ukusebenza komxube wekhonkrithi olungisiweyo uvakalelwa kakhulu ekusebenziseni amanzi, kwaye ezinye iingxaki zihlala zivela.
