Izvo zvinyorwa zvemadhaka zvakasiyana, uye zvikamu zvavo zvakare zvakare zvakasiyana. Madhaka mujecha rekongiri uye gravel rakakamurwa kuita zvikamu zvitatu: limestone poda, ivhu, uye calcium carbonate. Pakati pavo pakati pavo, ibwe reupfu pane iro rakatsvuka remajiseni nejecha rakabikwa pasi pegumi neshanu kupfuura 75 μm. Iyo ndiyo imwechete yechibereko chidimbu sejecha rakagadzirwa uye rine zvakafanana mineral. Chikamu chikuru cheCoco3, icho chiri chikamu chegakava rekuumbwa kwejecha rakagadzirwa.
.
Izvo zvinowanzoda kuti chikonzero chikuru chinokanganisa kongiri neLignosuleta uye naphthalene mvura yekudzora vamiririri kukwikwidza pakati pematope uye simende. Pachine tsananguro yakabatana pakatarisana nematope edope uye polycarboxylic acid-kuderedza mumiririri. Vamwe vadzidzi vanofunga kuti nheyo yekushanda yemadhaka uye mumiririri wekuderedza mvura akafanana neiyo yeiyo simenti. Iyo yemvura-inoderedza mumiririri inodhindwa pamusoro pepamusoro yeiyo simende kana matope poda nemapoka anonioni. Musiyano ndewekuti huwandu uye huwandu hwe adsorption yemubatanidzwa wemvura nemvura nematope hupfu hwakawanda kupfuura hwesimende. Panguva imwecheteyo, iyo yakakwira nzvimbo nzvimbo nzvimbo uye yakadzika midziyo yezvikara zvinobata zvakare mvura yakawanda uye kuderedza mvura yemahara mune slurry, iyo inobata zvakananga kuita kwekuvaka kongiri.
(2) Mhedzisiro yemaminerari akasiyana pakuita kwemvura kuderedza vamiririri:
Tsvagurudzo inoratidza kuti gaingo dendepe chete nekuwedzera kwakakosha uye mvura yekunyora kwemvura ichave neyakakosha maitiro pakubata kwekushanda uye gare gare manhamba emakonzo ekongiri. Mavara anowanzobatanidzwa mumatope muAggregates anonyanya kusanganisira kaolin, Vakasiyana naMontmorilon. Rudzi rumwe chete rwemvura-inoderedza yemvura ine madhiri akasiyana mumatope edopositions akasiyana, uye uyu mutsauko wakakosha pakusarudzwa kwemvura-kudzora mvura-yekudzora mvura-yekudzora emvura-madhiri amiririri.
(3) mhedzisiro yematope poda yezvinyorwa pane concrete zvivakwa:
Iko kushanda kwekushanda kwekongiri hakuiti kunongoita kuumbwa kongiri, asi zvakare inokanganisa iyo yakazotevera michina uye kusimba kwe kongiri. Iyo vhoriyamu yematope poda zvisingaitike, kuderera kana kuoma uye kuwedzera kana wanyorova. Sezvo matope emadhaka anowedzera, ingave iri polycarboxylate yemvura-kuderedza mumiriri wemvura-yekudzora-mhepo-yekudzora mvura, ichaderedza iyo mwero wekuderedza mvura, simba, uye kutsvedza kwekongiri. Kudonha, etc., kuunza kukuvara kukuru kukonganiso. Iyo National Standard "jecha rekuvaka" (GB / T14684-2011) Inosimbisa Concrete Conced %, uye matope ematope hahupfuure 1.0%; Kana iyo concrete simba giredhi iri pasi peC30, iyo mudhiro Powder yezvinyorwa hazvipfuure 5.0% uye madhaka block madhiri haapfuure 2.0%.
