Parizvino, kushandiswa kwepolycarboxylate superplasticizermvura inoderedza vamiririri yakajairika mukuvaka, nekuti kuita kwavo chigadzirwa kunogona kuvandudza simba rekuvaka uye einjiniya mhando.Ichi chigadzirwa chakasvibirira, chisingabatike, uye hachiputika, uye chinogona kutakurwa zvakachengeteka nechitima nemotokari.Kana iyo dosi yemvura inoderedza mumiririri inosvika 0.9% ~ 1.1%, kudonha kwekongiri ine mvura simende reshiyo ye0.12-0.16 uye jecha rine 38% rinogona kuramba rakachengetwa pamusoro pe250mm kwemaawa maviri, kuwedzera kunogona kusvika 600mm, nguva yekupedzisira yekuisa iri mukati maawa makumi maviri nemana, uye hapana chiitiko chekusarura.Simba rekumanikidzika pamazuva makumi mapfumbamwe kunyange pamusoro pe180MPa.Saka inobata basa rinokosha pakuvaka, uye zvinotevera zvichazivisa zvakanakira.
1. Izvo zvinyorwa zvealkali uye chloride ion zvinyorwa zvakaderera zvikuru, uye kuwedzerwa kwepolycarboxylate superplasticizerdoro raamai harikonzeri kukanganisa kukuvadzwa kumasimbi esimbi uye harina mhedzisiro yakaipa pane kongiri.Panguva imwecheteyo, chigadzirwa hachina munyu kunze kana kupenya panguva yakaderera tembiricha mwaka, zvichiita kuti zvive nyore kushandisa.
2. Inobatsira pakushanda kwekongiri yakasanganiswa, inoderedza kubuda ropa, inovandudza kutaridzika kwehutano uye kusimba kwekongiri yakaomeswa, uye inonyanya kukodzera kushandiswa mumapurojekiti akajeka.
3. Kongiri yakagadzirwa nayopolycarboxylate superplasticizermvura inoderedza agent mai doro haizoratidzi kuparadzaniswa kuri pachena kana kubuda ropa kunyangwe pasi pemamiriro ekudonha kwakanyanya, uye chitarisiko cheruvara rwekongiri yunifomu.Kana yakashandiswa kugadzira kongiri yepamusoro, kongiri ine kushanda kwakanaka, kubatana kwakanaka, uye iri nyore kusanganisa.
Saka polycarboxylate mvura inoderedza vamiririri inonyanya kukosha pakuvaka.Kana yakashandiswa, inowanzowedzerwa muchiyero, izvo zvisingangoiti kuti basa rive rakasimba asiwo rinoderedza njodzi dzakasiyana-siyana.Nekungonzwisisa zvivakwa zvezvinhu uye zvakanakira tinogona kuzvishandisa zvakanaka mune inotevera nhanho.Polycarboxylate superplasticizermvura yekudzikisa mvura inzvimbo yepamusoro yekudzikisa mvura uye yekuparadzira simende inoshandiswa mukuisa simende kongiri.Inoshandiswa mumapurojekiti akadai semigwagwa mikuru, mabhiriji, madhamu, tunnel, uye zvivakwa zvakakwirira.
