Maitiro emvura-anoderedza agent anokanganisa zvakananga shrinkage performance yekongiri. Pasi pekongiri imwechete inodonha, shrinkage rate yekongiri ine mvura-inoderedza mumiriri inosvika 35% yakakwirira kupfuura iyo yekongiri isina mvura-inoderedza mumiriri. Nokudaro, kutsemuka kwekongiri kunowanzoitika. Heino chikonzero:
1. Mhedzisiro yekudzikisa mvura inoenderana zvakanyanya nekongiri mbishi zvinhu uye kusanganisa zviyero.
Kuderedza mvura kwekongiri ndiyo tsanangudzo yakasimba, asi inowanzokonzera kusanzwisisana. Pazviitiko zvakawanda zvakasiyana, vanhu vanogara vachishandisa mwero wekudzikisa mvura kuratidza kudzikisa mvura kwechigadzirwa.
Pamuyero wakaderera, kutora polycarboxylate-inoderedza mvura semuenzaniso, yakaratidza kuti mvura yayo yekudzikisa mvura yakakura zvikuru kupfuura yemamwe marudzi emvura inoderedza mvura, uye ine simba rinoderedza mvura. Nekudaro, zvinofanirwa kucherechedzwa kuti kana zvichienzaniswa nemamwe maajenti ekudzikisa mvura, iyo inoderedza mvura yepolycarboxylate inoderedza mvura inobatwa zvakanyanya nemamiriro ebvunzo.
Pakati pezvinhu zvinopesvedzera kuita kweplasticizing yepolycarboxylate superplasticizer, chiyero chejecha uye chidimbu giredhi yeaggregates mukongiri zvakare ine simba rakakura. Zvichienzaniswa nemamwe akanyanya-anoshanda ekudzikisa mvura akadai senaphthalene akateedzana, iyo plasticizing mhedzisiro yepolycarboxylate inoderedza mvura inobatwa zvakanyanya nedhaka remukati meakaunganidzwa akakwana.
2. Mhedzisiro yekudzikisa mvura inotsamira zvakanyanya pamuyero wemugadziri wekudzikisa mvura.
Kazhinji, sezvo muyero wemvura-inoderedza mumiririri unowedzera, chiyero chekudzikisa mvura kwekongiri chinowedzerawo, kunyanya kune polycarboxylic acid-based-based-water-reducing agents, iyo dosi inobata zvakananga maitiro ekudzikisa mvura.
Nekudaro, pane zvisizvo mune zvinoshanda zvikumbiro. Kureva kuti, mushure mekunge imwe dosi yasvika, iyo yekudzikisa mvura "inoderera" sezvo dosi inowedzera. Izvi zvinodaro nekuti panguva ino musanganiswa wekongiri unova wakaomeswa, kongiri inotambura nekubuda ropa kwakanyanya, uye Mutemo wekudonha hauchagone kuratidza hupfumi hwayo.
3. Kuitwa kwemusanganiswa wekrete yakagadzirirwa kunonyanya kukoshesa kushandiswa kwemvura.
Zviratidzo zvekushanda zvekongiri musanganiswa zvinowanzoratidzwa muzvinhu zvakadai sekuchengetedza mvura, kubatana, uye fluidity. Concrete yakagadzirwa uchishandisa polycarboxylic acid-based superplasticizers haigaro kuzadzisa zvizere zvinodiwa zvekushandisa. Kuitwa kwemusanganiswa wekongiri wakagadzirirwa kunonyanya kunetseka pakushandiswa kwemvura, uye mamwe matambudziko anowanzoitika.
