Kuumbwa kweiyo simende uye zvigadzirwa zvemasimisiki zvakaoma uye zvinoshanduka. Kubva pamaonero okushamwaridzana-kupararira maitiro, hazvigoneke kuwana mumiririri wekuderedza mvura iyo yakakodzera kune zvese. NyangwePolycarboxylate Mvura-inoderedza mumiririri ane simba rakakura kupfuura naphthalene Series, ichiri inogona kuve nehurombo hwekuchinja kune mamwe ma cerments. Iyi shanduko inofungidzirwa zvakanyanya mu: yakaderedzwa mvura yekudzora mvura uye yakawedzera kurasikirwa kwekutsvedza. Kunyangwe kana chiri chinhu chimwe chete, mhedzisiro yemvura inoderedza mumiririri ichave yakasiyana kana bhora rakanyara kune rakasiyana.
Phenomenon:Chiteshi chekusanganisa chinosanganisira imwe p-042.5r simende munzvimbo yemunharaunda kuti ugovaniswe kuC50 Conscrete kunzvimbo yekuvaka. Inoshandisa apolyarboxylatesUpplasticasizermvura-inoderedza mumiririri. Paunenge uchigadzira kongiri yemasanganiswa, inowanikwa kuti huwandu hwemumvura-kudzora kwemvura inoshandiswa muchisimba zvishoma kupfuura mamwe mitezo, iyo slump yefekitori musanganiswa waive wakaonekwa seyakayerwa kuti uve 21MMM. Pandakaenda kunzvimbo yekuvaka kuti ndirege kuburitsa kongiri pombi, ndakaona kuti rori haina kukwanisa kuburitsa kongiri. Ini ndakazivisa iyo fekitori yekutumira mbiya. Mushure mekunge mumiririri wekuderedza mvura akawedzerwa uye wakasanganiswa, iyo inotsvedza yaive yekuona yaive 160mm, iyo yakasangana nezvinodiwa zvekupomba. Nekudaro, panguva yekusunungura maitiro, zvakaonekwa kuti zvaisakwanisa kutsigirwa. Rwiyo rwekongiri rwakadzoserwa pakarepo, uye huwandu hwakawanda hwemvura uye hushoma hwekudzora mumiririri akawedzerwa. Iyo yemvura yemvura yaisanyungudutswa uye ichangobva kusimbiswa mutiraki yemusanganiswa.
Kuongorora Kuongorora:Isu hatina kuomerera pakuitisa shanduko dzinoenderana neAdminture pane yega yega batch yeSement usati wavhura.
Kudzivirira:Bata bvunzo inosungirirwa neyekuvaka musanganiswa chiyero chega chega chegedhi yeiyo simende usati wavhura. Sarudza yakakodzera admixture. "Gangue" sechibvumirano cheSement chine kusarudzika kushamisika kune polyarboxylate sUpplasticasizermvura kuderedza vamiririri, saka dzivisa kuishandisa.
2.Sensitivity yekushandisa mvura
Nekuda kwekushandiswa kwePolycarboxylate Mumvura anoderedza mvura, mvura yekudyidzana yemakongiri yakaderedzwa kwazvo. Iyo mvura yekudhonza yekongiri imwechete kongiri inonyanya 130-165kg; iyo yemvura-simenti ratio ndeye 0.3-0,4, kana isingasviki 0,3. Panyaya yeyakaderera mvura yekushandisa, kudzvanywa mukuwedzera kwemvura kunogona kukonzera shanduko huru mukutsvedza, zvichikonzera musanganiswa wekongiri kuti uwedzere kuwedzera mukutsvedza uye kubuda ropa.
Phenomenon:Chiteshi chekusanganisa chinosanganisira P-032.5R simende kubva kune imwe cerment fekitori kugadzirira c30 kongiri. Chibvumirano chinoda kuti kutsvedza kuenda kunzvimbo yekuvaka ndeye 150mm: t30mm. Kana kongiri inobuda iyo fekitori, iyo yakayerwa slump ndeye 180mm. Mushure mekutakurwa kuenda kunzvimbo yekuvaka, kongiri inoyerwa panzvimbo yekuvaka. Iko kutsvedza kwaive kwe21omm, uye marori maviri emakongiri akadzoserwa mukuteerana. Paakadzokera kufekitori, yakasimbiswa kuti kutsvedza kwakange kuchiri 21omm, uye kwaive nekubuda ropa uye kusechi.
Chikonzero:Iyi simenti ine yakanakira kushandurwa kweiyi mumiririri wekudzora mvura, uye huwandu hwemumvura-kudzora mumiririri zvakakura zvishoma. Nguva yekusanganisa haina kukwana, uye kutsvedza kwekongiri kana uchisiya muchina hausi wechokwadi kutsvedza nekuda kwenguva pfupi yekusanganisa.
Kudzivirira:For siment iyo inoerera kune iyo doisa ye polyarboxylatesUpplasticasizerMvura-kuderedza kufungidzira, iyo dosage yeAdmixture inofanira kuve yakakodzera uye kuongorora chokwadi kunofanirwa kuve kwakakwirira. Nyatsotambanudza nguva yekusanganisa. Kunyangwe neye twin-shaft yakamanikidzwa musanganiswa, nguva yekusanganisa haifanirwe kunge isingasviki makumi mana masekondi, kunyanya anopfuura makumi matanhatu masekondi.
