Basa rekongiri rekongiri rekunyepedzera nderokuvandudza kuyerera kwenzvimbo dzekongiri uye kuderedza huwandu hwezvinhu zvekushandisa mukokongiri. Naizvozvo, kubvumirana kwakabatana kunoshandiswa zvakanyanya munzvimbo dzakasiyana siyana dzekuvaka.
Maitiro echiito cheConcrete admixture:
Iyo inowanzoshandiswa naphthalene-based admtures uye polycarboxylate-based adminture ndeye organic makomputa nehuremu hwakanyanya (kazhinji 1500-10000) uye ndezveboka revaridzi.
Iyo Molecule yeSurfactant ine chimiro cheBipolar, imwe mugumo ndeye isiri-polar lipophic group (kana isiri-polar hydrophobic group), uye imwe mugumo iboka rePolar hydrophilic boka. Mushure mekunge siractant
A. Adsorption-kupararira
Iyo fluidity yemusanganiswa wekongiri inoenderana nehuwandu hwemvura yemahara mukongiri. Mushure mekunge Admixture inowedzerwa kune kongiri, iyo spinement zvimedu zvinokonzerwa neyakaenzana neyakawirwa nemamolekita yemubatanidzwa pamusoro peiyo nzvimbo yemasimendi, zvichikonzera kudzora kwemagetsi pakati pavo. Nekuda kweizvozvo, chimiro chekutanga cheSumbeni chaparadzwa, uye huwandu hwakawanda hwemvura emahara hunosunungurwa, hunowedzera zvikuru ruzha rwemusanganiswa wekongiri.
B. kunyorova
Nekuda kwekutungamira urongwa hwekurongedza kwemamolecules pamusoro pepamusoro pepfungwa zvikamu, iyo monolecular yakagadziriswa mvura yemvura inoumbwa. Iyi firimu yemvura inowedzera nzvimbo yekuonana pakati peiyo simende zvikamu nemvura kune rumwe rutivi, uye ine imwe yekunyorova kune rumwe rutivi. Naizvozvo, simende iri hydrate yakazara uye simba reSement rinowedzera nekukurumidza.
Izvo zvakakosha mabasa ekongiri admixture:
1. Pasina kuderedza iyo unit mvura yekudhara, huwandu hwemvura hunoramba husina kuchinjika, hunovandudza kushanda kwekongiri nyowani uye kunovandudza mapopoma; Nekuda kweiyo nzvimbo yakawedzera kwazvo yekubika pakati pemasimendi emasimendi nemvura, iyo simende iri hydrate yakazara, kunyangwe iyo mvura-binder rutio inopinda, iyo Simba reConcrete rinowanzove nekuvandudzwa.
2..
3. Pasi pemamiriro ekuchengetedza imwe simba, kuderedza huwandu hwezvinhu zvekushandisa, kuderedza mvura yemvura, chengetedza iyo mvura-binder ratio isina kuchinjika, uye chengetedza simende uye zvimwe zvinhu zvekumisikidzwa.
Maitiro Ekuita Zvakasimba uye Shandisa Kongiri Admixture:
Kutsvaga zvakanaka uye kushandisa zvinyoronyoro zvinogona kuburitsa kukosha kwehupfumi uye nehunyanzvi. Izvo hazvigone kungovandudza simba rekongiri, asi zvakare kuderedza mutengo wekongiri retio.
Iyo nzira chaiyo iri seinotevera:
a. Test link
Kuedzwa uye kuyedzwa kwezvikamu zvakasiyana zvehunyanzvi zveAdminture ndeye yakakosha chinongedzo usati watenga kutaurirana. Kuburikidza nemubvunzo, miganho yekubvumidzwa yezvinhu zvakasiyana-siyana zvehunyanzvi zveAdmixture inofanira kutsanangurwa. Kusanganisira iyo yakasimba yemukati yeAdmixture, kuderedza kwemvura, density, slurry fluidity, kongiri yekudzora mvura yekudzora huwandu uye humwe hunhu hwehunyanzvi. Zvinokurudzirwa kuti kongiri yekudzora mvura yekudzikiswa kweyero inoshandiswa seyakakosha chiratidzo kuyera iyo mhando yemhando yemhando yezvibvumirano.
b. Kuwana
Mushure mekukodzera kwekukodzera kweAdmixture inojekeswa, kutaurirana kwemitambo kunogona kutanga. Zvinokurudzirwa kuti vagadziri veAdmintelure vanofanira kukoka mabhesi maererano nezvinodiwa zvinodiwa zvinoenderana nemuyedzo. Pamungambo kuti mhando yekupa iyo densture haina kuderera pane zvinodiwa zvekudaidzira, mutengesi anofanirwa kutsanangurwa zvichienderana neshoko rekukunda iro rakaderera mutengo.
Panguva imwecheteyo, kusarudzwa kweConcrete Vagadziri vanofanirwa kufunga nezvechiitiko chechigadzira, chifambiro chekutakura uye kupa hunyanzvi hwekuita zvirimwa, uye mushure mekurapa kweinjiniya, uye mushure mekutengesa mabasa ebasa uye mazinga. Sechiratidzo chimwe chete chekugadzira mugadziri.
c. Kubvuma Kubatanidza
Iyo yekusanganisa chiteshi inofanirwa kuyera Admture Inokurudzirwa kusiyanisa pakati pekiyi zviratidzo uye zvinongedzo zvirevo. Kubudikidza nekuita kwenguva refu, munyori anotenda kuti zviratidzo zvakakosha zveAdMixture ndeye mwero wekuderedza mvura Zvinongedzo zviratidzo ndeyekuwedzera (chaiyo gravity), zvemukati zvakasimba uye fluidity yeiyo coment paste. Nekuda kweiyo nguva yekuyedza, iyo technical zviratidzo zvinowanzoedzwa mukubvumidzwa kwekubvuma ndeye density, iyo flidiity yeiyo coment paste uye iyo yekudzora mvura yekudzora (moter).
