Hunhu hwezvemvura-kuderedza mumiririri zvakananga zvinokanganisa kuita kwekongiri. Pasi peiyo imwechete concrete slump, iyo shrinkage chiyero chekongiri ine mumirimo-kuderedza kwemvura ndeye 35% yakakwirira kupfuura iyo yekongiri isina mumiririri wekuderedza mvura. Naizvozvo, makonzo emakona anokwanisa kuitika. Heano nei:
1. Kuderedzwa kwemvura kunoenderana zvakanyanya pane kongiri kana kusanganisa zviyero.
Rwiyo rwekudzora rwemvura rwekongiri ndeye tsananguro yakasimba kwazvo, asi inowanzokonzeresa kusanzwisisana. Pane dzimwe nguva dzakasiyana siyana, vanhu vanogara vachishandisa mwero wekudzora mvura kuratidza mvura yekudzora mvura yechigadzirwa.
Pazasi pezasi, kutora Polycarboxyboyclate yemvura-kuderedza kwemvura-semuenzaniso, zvakaratidzwa kuti chiyero chayo chinodzora mvura chakakura kupfuura mamwe marudzi ekuderedza mvura, uye ine mari inoderedza mvura iri nani. Nekudaro, inofanira kucherechedzwa kuti ichienzaniswa nevamwe vamiriri vemvura, iyo mvura-inoderedza mari yePolycarboxy yemvura-kuderedza vamiririri vanokanganiswa nemamiriro ekuedzwa.
Pakati pezvinhu zvinokonzeresa kupokana nePolycarboxylate Superpasticastizer, iyo jecha chiyero uye chimedu chekuunganidza maAggreate zvakare mune zvakare zvakakura. Kuenzaniswa nedzimwe yakakwira-yekubudirira kwemvura-kuderedza madumbu senge naphthalene Series, kupurasanikidza kupokana kwePolycarboxy yemvura-kuderedza vamiriri anokanganiswa kwazvo nemadhaka ezvematongero akanaka.
2. Iyo mvura-inoderedza mhedzisiro inotsamira zvakanyanya pane dosage yemvura-inoderedza mumiririri.
Kazhinji, sedanda rekuwedzera kwemvura, kuderedza mvura kongiri inowedzera, kunyanya yePolycarboxycal acid-inokonzeresa mvura, iyo dosage inobata zvakananga nemvura-kuderedza mvura.
Nekudaro, pane izvo zvinopihwa mune zvinoshanda zvinoshandiswa. Ndokunge, mushure meimwe dosi yasvika, iyo mvura-inoderedza mari "inoderera" sezvinoita dopage inowedzera. Izvi zvinodaro panguva ino musanganiswa wekongiru unowedzera kuomeswa, kongiri inotambura nekubuda ropa zvakanyanya, uye mutemo wekutsvedza hauchazombotaure.
3. Kuitwa kweiyo yakagadzirirwa kongiri musanganiswa inonyatsoteerera kumvura.
Zviratidzo zvechiratidzo zvechiratidzo zvekongiri zvinowanzo kuratidzwa mune zvikamu zvakaita sekuchengetwa kwemvura, kubatana, uye fluidity. Concrete yakagadzirirwa kushandisa Polyarboxylic acid-based Superpanders haigaro kuzadzisa zvinodiwa zvinoshandiswa. Kuita kweiyo yakagadzirirwa kongiri musanganiswa inonzwa zvakanyanya kumvura, uye zvimwe zvinetso zvinowanzoitika.
