Iko kuchinjika uye kusapindirana pakati peinonzi kongiri admixture uye simende inogona kutariswa seizvi: Paunenge uchigadzira kongiri (kana dhaka), zvinoenderana nehunyanzvi hwekutsanangurwa kwekongiri admixture application, imwe admixture yakaongororwa kuti isangane nemiyero yakakodzera inogona. kuwedzerwa kumitemo. Kana simenti inoshandisa musanganiswa wezvakasiyana-siyana inogona kuunza mhedzisiro yaunoda, simenti inopindirana nemusanganiswa. Pane zvinopesana, kana mhedzisiro yacho isina kugadzirwa, simenti uye musanganiswa hazvina Kufanira. Semuyenzaniso, kongiri superplasticizer inowedzerwa kune kongiri yakagadzirwa kubva kune mashanu akajairwa Portland simende (yakaedzwa kuti isangane nezvinodiwa zvepamusoro-inoshanda yekudzikisa mvura miyero, uye zvimwe zvinhu zvese zvakafanana, pane imwe Concrete yakagadzirwa kubva simende ine kushomeka kwakakomba mukati. chiyero chekudzikisa mvura Mimwe simiti haina dambudziko iri, saka, inogona kutariswa kuti simiti iyi haina kukodzera kune superplasticizer, uye mamwe simiti Iyo yakanyanya-inoshanda yekudzikisa mvura yakakodzera imwe simende inosanganiswa neanomhanyisa coagulant (yakaedzwa kuti isangane nemiyero yakakodzera), asi iyo yakakurumidza kuseta mhedzisiro haiwanikwe, Kuwedzera retarders havawane kwakaringana retarding mhedzisiro, zvese OK zvinoonekwa zvisingaenderane pakati pemisanganiswa uye simende.
Cement fineness simenti zvimedu zvine simba adsorption kumamorekuru anoderedza mvura. Mune simende slurry ine mvura-inoderedza agent, iyo yakatsetseka iyo simenti particles, iyo yakakura nzvimbo chaiyo yepamusoro, iyo ndiyo, iyo inoderedza mvura inogadzirisa mamorekuru. Huwandu hweadsorption hwakakura zvakare. Naizvozvo, kana iri iyo yakaenzana yemvura inodzikisa mumiriri, iyo plasticizing mhedzisiro yakashata kune simende ine yakakwira fineness.
Iye zvino vamwe vanogadzira simende vanowanzovandudza simba rekutanga resimende. Kune iyo simende yakanaka, kuitira kuti uwane zvirinani plasticizing mhedzisiro, zvinodikanwa kuwedzera huwandu hwemvura inoderedza mumiriri. Iko kutsva uye kutonhora kwesimende kutsva, uye plasticizer yemvura inoderedza mumiririri Musiyano unoenderana wakaipa. Izvi zvinodaro nekuti iyo yakanaka yemagetsi midziyo yesamende nyowani yakasimba uye adsorption kugona kweiyo yekudzikisa mvura mumiririri yakakura. Iyo yakakwirira tembiricha ye simenti, iyo yakaipisisa iyo plasticizing mhedzisiro yemvura inodzikisa agent. Iko kurasikirwa kwekudonha kunokurumidzawo. Naizvozvo, kana mamwe mafekitari ekugadzira kongiri anoshandisa kongiri ichangobva kugayiwa uye ichiri kurasikirwa nekupisa, mwero wekudzikisa mvura wakadzikira uye kurasikirwa kwekudonha kunokurumidza. Kunyangwe kuoneka mu blender Chang condensation zvichingodaro, isu tinofanirwa kuterera uye kudziviswa.
