1. Mineral kuumbwa
Zvinhu zvikuru ndizvo zviri mukati meC3A uye C4AF. Kana zvirimo zvezvinhu izvi zvakaderera, kuenderana kwesimu uye kuderedza kwemvura kuchave kwakanaka, pakati peiyo c3a ine simba rakasimba pane shanduko. Izvi zvinonyanya kukosha nekuti iyo mvura inoderedza inotanga adsorbs c3a uye c4f. Uye zvakare, iyo hydration chiyero cheC3A chakasimba kupfuura icho cheC4A, uye chinowedzera nekuwedzera kweiyo simeness. Kana zvimwe zvikamu zveC3A zviri musikenzo, zvichatungamira zvakananga kune hushoma hwemvura yakavezwa mumvura, zvichikonzera kuderera kwehuwandu hwekusuwa.
2. Kufunga
Kana iyo simende iri yakanaka, iyo chaiyo nzvimbo nzvimbo ichave yakakura, uye iyo mari yekurova ichave pachena. Kuti udzivise iyi fluclerus chimiro, imwe huwandu hwemvura kuderedza inoda kuwedzerwa kwazviri. Kuti uwane zvakakwana kuyerera mari, zvinodikanwa kuti uwedzere kushandiswa kwemvura kuendesa kune imwe nhanho. Mumamiriro ezvinhu akajairika, kana simende iri yakanaka, iyo nzvimbo yakatarwa nzvimbo yakakwirira, uye pesvedzero yekudziya kwemvura pane huwandu hwakawandisa huchawedzera, zvichiita kuti zviome kuve nechokwadi chekusimbisa kweSEENT. Naizvozvo, mune chaiyo yekugadzirisa kongiri ine huwandu hwemvura yakakwira, iyo-kune-nzvimbo-nzvimbo inofanirwa kunyatso kudzorwa kuti ive nechokwadi chekuti simendi uye inoderedza mvura yakasimba.
3. Grading of coment zvidimbu
Simba rezvikamu zvechikamu chekutenderera pamusoro peSement Scement chinonyanya kuratidzwa mune zvemukati zvechikamu chakasarudzika, kunyanya zvirimo, izvo zvine chekuita nekushambadzira kwemvura inoderedzwa. Zvemukati zvezvinyorwa zvisingasviki 3 macoroni musicent zvinosiyana kwazvo nevadzidzi vakasiyana-siyana vane tsika dzakasiyana, uye rinowanzogoverwa pakati pe8-18%. Mushure mekushandisa iyo yakavhurika chigayo system, iyo chaiyo nzvimbo yemasimende yakagadziridzwa kwazvo, iyo ine yakanyanya kukanganisika pane shanduko yeiyo simende uye inoderedza mvura.
4. Kutenderera kweiyo simenent zvidimbu
Pane nzira dzakawanda dzekuvandudza kutenderera kwesimende. Munguva yakapfuura, zvimende zvidzidzo zvaiwanzove pasi kuti urege kuchema nemakona. Nekudaro, mune chaiyo yekuvhiya maitiro, nhamba yakakura yeakanaka poda maseru anowanzoonekwa, ayo ane zvakananga zvakanyanya mukuita kwesimendi. Kuti vagadzirise zvinobudirira dambudziko iri, kutenderera kwebhora kuchema tekinoroji kunogona kushandiswa zvakanyatsoshandiswa, uko kunogona kuvandudza kwazvo spomerization ye simenti, uye kuderedza kurasikirwa kwenguva, uye kupfupisa simbiso yekukuya. Mushure mekutenderera kweiyo spoment zvidzidzo zvinovandudzwa, kunyangwe hazvo mhedzisiro yacho pakatarisana nemvura yekudzora mvura haina kukura kwazvo, inogona kuvandudza fluidity yeiyo coment paste kusvika pamwero mukuru. Ichi chiitiko chacho chichava pachena kana huwandu hwemvura uwande hwakashandiswa zvidiki. Mukuwedzera, mushure mekuvandudza kutenderera kweiyo simenti zvikamu, iyo fluidity yeiyo coment paste inogona zvakare kuvandudzwa kune imwe nhanho.
5. Zvakasanganiswa zvinhu
Mukushandiswa kwazvino kwesimbe munyika yangu, zvimwe zvinhu zvinowanzobatanidzwa pamwe chete. Izvi zvinosanganiswa zvinosanganiswa zvinowanzo kusanganisira kuputika chirahwe, kubhururuka, kweganda pwere, et. kuwanikwa. Kana volcanic adh uye marasha gangue anoshandiswa semidziyo yakasanganiswa, zvakaoma kuwana kusanganisa kwakanaka kusanganisa. Kuti uwane mukana wekudzora kwemvura zviri nani, imwe mvura kuderedza inodiwa. Kana kubhururuka ash kana neeolite kunosanganisirwa mune yakasanganiswa zvinhu, kurasikirwa nekukasira kazhinji zvine hukama zvakananga kune zvakajeka kune akapfeka matovheni Asinganyanye kurasikirwa nekukasira, mvura yakawanda inodikanwa, uye yakakwira iyo inoputika yechinhu chipi chipi zvacho chivakwa. Mushure mekudzidzira kwakawanda, zvakaratidzwa kuti kusagadzikana kwezvinhu zvakasanganiswa kuti zvive zvekusanganisa uye nemvura kuderedza zvinonyorwa mune zvinotevera kutsiva pasita, iyo fluidity yeaste ichave yakasimba se kutsiva chiyero chinowedzera. ② Kana kubhururuka Ash inoshandiswa zvakananga kutsiva siment paste, iyo yekutanga fluidity inogona kuderedzwa zvakanyanya mushure mekutsiva zvinhu zvinopfuura 30%. ③ Kana Zeolite ichishandiswa zvakanyatsotsiva simende, zviri nyore kukonzera kukwana kwekutanga kwekutanga kweiyo paste. Mumamiriro ezvinhu akajairwa, nekuwedzera kweiyo slag kutsiva chiyero, kuyerera kuchengetedza kweSement Paste ichawedzerwa. Kana kubhururuka ot inowedzera, iyo yekuyerera kurasikirwa kweiyo paste ichawedzera kune imwe nhanho. Kana iyo zeolite kutsiva chiyero chinopfuura 15%, kurasikirwa kwechikepe kwea paste kuchave kuri pachena kwazvo.
6. Mhedzisiro yeAdminture Type pane iyo Fluidity yeSetsional Paste
Nekuwedzera imwe chikamu chevanorwiswa kuConcrete, mapoka e hydrophobic ezvekutungamira achange achibvumidzwa pamusoro pechikamu chechisimba, uye mapoka ehydrophilic anozonongedzera kumhinduro, nekudaro achiumba adsorption firimu. Nekuda kwekutungamira kwekutungamira kweAdsorption yechiitiko, pamusoro peiyo simenti zvidimbu zvichave nemhosva yeiyo chiratidzo. Pasi pemhedzisiro yakafanana nemhosva dzinodzedzereka, iyo simende ichaumba kupararira kweiyo flucesleent chimiro chekusunungurwa kwemvura, kuitira kuti zvirove zvinokonzerwa nemvura, nekukanyatsovandudza mapopoma emuviri wemvura kune imwe yemvura kukura. Kuenzaniswa nedzimwe adminture, chinhu chikuru chePolyhydroxy acid ACMIXT ndezvekuti ivo vanogona kugadzira mapoka nemhedzisiro dzakasiyana pane imwe miganho yejeni. Kazhinji, hydroxy acid admixtures zvine simba rakakura pane iyo fluity yesimendi. Mugadziriro yekugadzirira yeakakwira-simba kongiri, ichiwedzera imwe chikamu chePolyhydroxy acid AcMixtures inogona kuwana zviri nani kugadzirira mhedzisiro. Nekudaro, mune iyo nzira yekushandisa polyhydroxy acid ACM ADMINTES, ine zvido zvakakwirira pakuita kwekuita kweiyo simenti zvinhu. Mukushandiswa chaiko, musanganiswa wacho unonamira ku viscosity uye kunamatira kuzasi. Mukushandiswa kwacho kwekupedzisira kwechivako, kunowanzoitawo mvura yekutsvaga mvura uye kuoma. Mushure mekudengenyeka, inowanzoitika kune roughness, mitsara yejecha, uye maburi emhepo. Izvi zvine chekuita zvakananga kusingakwanisike kwe polyhydroxy acid admixtures ine simende uye mineral admtures. Polyhydroxy acid admixtures ndiyo inomiririra neyakaipisisa shanduko kuti isimbe pakati pemhando dzese dzevanorongeka.
