Mhedzisiro yeMvura Reducer paShrinkage Cracking yeCommercial Concrete

Nekuenderera mberi kwekuvandudza nzanga uye tekinoroji yekugadzira, muindasitiri yekuvaka, kunaka uye kuita zvinodiwa zvekongiri zvakanyanya kuomarara, uye hutano hwechivako hunobatwa zvakananga nekushanda kwekrete.

Kugadzirwa kwekongiri admixtures kwakagadzirisa zvakanyanya dambudziko iri.Iyo yekutengesa kongiri yakawedzerwa nemvura inoderedza mumiririri yakavandudza zvakanyanya kushanda kwekushanda., yakavandudza kusimba kwekongiri, uye yakawedzera kusimba uye hupenyu hwebasa hwekongiri, inova budiriro huru kune indasitiri yekuvaka.

Mvura inoderedza maajenti anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana dzakakosha, kunyanya zvivakwa zvepamusoro, zvivakwa zvepamusoro-soro, high-speed railways, migwagwa mikuru, zviteshi zve subway, zvivako zvemagetsi enyukireya, etc., izvo zvinokurudzira kukurumidza kusimudzira uye kuchengetedzwa kwakasimba kweindasitiri yekuvaka.

The mvura inoderedza chinhu chinowedzera chinogona kuderedza zvakanyanya kana kuderedza zvakanyanya mvura yekusanganisa kongiri panguva yekusanganiswa kwekongiri, kunatsiridza kuyerera uye kusimba kwekongiri.Kudzidzira kwakaratidza kuti kana iyo inoderedza mvura inowedzerwa kune kongiri., kana simba risingadi kuwedzerwa, huwandu hwesimende hunogona kuderedzwa zvakanyanya, uye kuwirirana kwekongiri kunogona kuvandudzwa.Naizvozvo, iyo yekudzikisa mvura mumiriri chinhu chakakosha chekuwedzera mune yekutengesa kongiri.

Kuti uwedzere kuvandudza hupfumi hwehupfumi hwekongiri yekutengeserana, mabhizinesi ekugadzira kongiri anofarira kushandisa maajenti ekudzikisa mvura ane yakakwirira-yekudzikisa mvura zvivakwa kuvandudza simba rekongiri kana kudzikisa zvakanyanya huwandu hwesimende uye kuderedza mitengo yekugadzira..

Saizvozvo, uku kusanzwisisana kukuru. Kunyangwe kuderedzwa kwemvura kunobatsira kuvandudza simba rekumanikidza rekongiri, kuderera kwemvura zvakanyanya kunogonawo kukanganisa kusimba kwekongiri.

Kunyangwe kuderedzwa kwakakodzera kwemvura kunobatsira kudzikisa kongiri shrinkage rate, zvinofanirwa kucherechedzwa kuti pakugadzira kongiri musanganiswa ratio, iyo mvura inoderedza basa re superplasticizer yakatariswa, uye mvura-ku-binder reshiyo yezvakagadzirwa zvakaderera, zvakadai sokumwe kuderedzwa. Kuwanda kwemvura inoshandiswa kuchawedzera shrinkage yekrete uye kuwedzera shrinkage yekrete.

Apo kongiri yekutengeserana inoderedza zvakanyanya kuwanda kwesamende, kunyangwe simba rekumanikidza harina kudzikiswa, kusimba kwesimba kunodzikira sezvo vhoriyamu yedombo resimende yakaomeswa mukongiri inoderera.

Nekuda kwekuderera kwehuwandu hwesamende, kongiri grout layer yakanyanya kutetepa, izvo zvichakonzera mamwe microcracks mukongiri.Ehe, microcracks haina mhedzisiro pane kongiri inomanikidza simba, asi mhedzisiro yekongiri inorema uye zvimwe zvivakwa hazvigone kuderedzwa.Kuderedzwa kukuru kwesimende zvinhu kunokanganisawo elastic modulus uye zvinokambaira zvekongiri., kuita kuti kongiri iwedzere kubatwa nekuputika.Paunenge uchigadzira kongiri yekutengeserana, mwero wekongiri wekudzikisa mvura uye huwandu hwesimende zvinhu zvinofanirwa kutariswa zvizere. Usamboderedza mvura kana kuderedza zvakanyanya simenti.

Cie-China.org ndiyo inotungamira furo kongiri yekuwedzera inopa inopa kongiri inopupuma mumiriri, superplasticizer,foam kongiri simba rekusimudzira kune lightweight kongiri, CLC inovhara. Kana uri kutsvaga foaming-agent, ndapota inzwa wakasununguka taura nesu.
