Kuzvimiririra cement / mongwe (yekuzvimiririra simende / yakacheneswa) chinhu chakabikwa cheStement Chivakwa chinogona kuumba uye kuzvimanikidza nekuzvimirira panguva yekuvaka. Nekuda kwekukakavara kwayo kwekuwedzera kwekuita uye kusununguka kwekuvaka, kuzvidzora cement / mongwe inoshandiswa zvakanyanya muGrolopaji uye mapurojekiti ekushongedza. Iyo inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, dzakadai seplors dzevakabva, zvivakwa zvekutengesa uye maindasitiri. Iko kuoma uye kwehunyanzvi zvinodiwa zve formula kwayo zvakakwira. Izvi zvinotevera kuongororwa kwakadzama kweiyo yekuzvibatanidza cement / moter formula.
1. Kuumbwa kwekuzvimiririra coment / dhaka
Kuumbwa kwekutanga kwekuzvimiririra / mongwe kunosanganisira: simende, yakanaka aggregate (yakadai se quartz jecha), admixture, mvura uye midziyo yakagadziridzwa. Iyo kiyi inorara mukushandiswa uye kugadziriswa kwekugadziriswa kwezvibvumirano. Izvi zvinotevera zvichave zvinoongororwa zvakadzama zvechikamu chimwe nechimwe:
Simende
Simende ndiyo huru yekubatanidza zvinhu zvekuzvimiririra coment / dhaka. Iyo inowanzoshandiswa mhando yeiyo simende yakajairika Portland cement, inopa simba kune dhaka. Nekudaro, kuitira kuti uwane fluidity yakanaka uye kuzvimanikidza kuzvimiririra, kusarudzwa kwesimende kuchagadziriswa zvinoenderana nezvinodiwa chaizvo. Mune mamwe mafambiro, masemero akakosha senge chena simende kana simende yeltrafine inoshandiswawo kuwana zvishoma nezvishoma uye kusarudzika.
Yakanaka aggregate (Quartz jecha)
Saizi yehukuru uye kugoverwa kweiyo yakanakisa aggregate ine yakakosha pesvedzero pakuvaka kwekuita kwekuzvienzanisira. Quartz jecha kazhinji ndiyo huru yekuunganidza yekuzvimirira marara, uye saizi yemukati inowanzoitika pakati pe1.1mm uye 0.3mm. Yakanakisa aggregate isingori chete kugadzikana kwekuzvimiririra simenti, asi zvakare inosarudza kupedzisa kwaro kunopera. Iye anokakavara zvimedu zveggregate, zvirinani kusvinura, asi simba raro rinogona kuderera. Naizvozvo, hukama pakati pehunhu uye simba zvinoda kuve pakati nepakati penzira yekuenzanisa.
Admixtures (Zvigadzirwa zvakagadziriswa)
Admixtures ndeimwe yezvikamu zvakakosha zveComment coment / dhaka. Ivo vanonyanya kushandiswa kuvandudza fluidity, wedzera nguva yekuvaka, kuvandudza kupaza kupesana nekuwedzera kuderedza. Zvakajairika Admixtures zvinosanganisira mvura inodzikiswa, mapurasitiki, Taugiger, diafreeze vamiriri, nezvimwe.
Mvura inobhadhara: Inogona kuderedza zvinobudirira kuyerera kwemvura, kugadzirisa fluidity, uye ita setete pasita nyore kuyerera ndokupararira.
Plasticzez: Kuvandudza kudenha uye kupenga kuramba kweura, uye kugadzirisa matanho ayo panguva yekuvaka.
Mazamu emumiriri: Kuwedzera shoma shoma yemumiriri anobatsira kugadzirisa kumeso kwepasi pevhu, zvekuti inogona kuzvivenga.
Mvura
Iyo huwandu hwemvura yakawedzerwa ndiyo kiyi yekutsiva iyo yekuvaka mashandiro ekuzvimiririra coment / dhaka. Maitiro ehukama hwesimendi inoda huwandu hwakakodzera hwemvura, asi mvura yakawandisa inokanganisa simba uye kusimba kwerudzi. Iyo chiyero chemvura kusvika kument inowanzo kudzorwa pakati pe 0.3 uye 0.45, iyo inogona kuve nechokwadi chekuti moturu ane madiki akakodzera uye simba rayo rekupedzisira.
2. Ratio uye kugadzirira kwekuzvimiririra simenti / dhaka
Iyo chiyero chekuzvimiririra cement / mongwe inoda kuchinjirwa zvinoenderana nenzvimbo yekushandisa, zvinodikanwa zvinodiwa uye mamiriro ekuvaka. Nzira dzakajairika dzekuenzanisira dzinosanganisira uremu chiyero, vhoriyamu ratio uye simende: Aggregate Ratio. Munguva yekugadzirira maitiro, kuganhurika kwakaringana ndiko hwaro hwekuita kuti durmar performance inosangana netarisiro.
Simende: jecha ratio
Mune mutambi wechinyakare, chiyero cheSystem kujecha iri pamusoro pe1: 3 kana 1: 4, asi iyo chiyero chekuzvimanikidza simendi / mongwe inowanzoda kugadzirwa. Chinhu chakakwirira chekamensi chinobatsira kuvandudza simba uye fluidity, nepo jecha rakawandisa richaita kuti riwedzere kuderedza. Naizvozvo, simendi ine mwero:
Ratio yeAdmixture
Iyo huwandu hwesmixture yakawedzera yakakosha pakuita kwekupedzisira kweiyo dhaka. Mvura inoderedza inowanzowedzerwa ku 0.5% kusvika 1.5% (zvichibva pane simende), nepo mapurasitiki uye maungira anowedzerwa maererano nemamiriro ezvinhu akaenzana, aine kuwedzerwa kwe1.3% kusvika 1%. Kunyanya kuyambira kwakawanda kunogona kukonzera kusagadzikana kwemutungamiriri, saka kushandiswa kwaro kunofanira kudzorwa zvakanyanyisa.
Ratio yemvura
Iyo chiyero chemvura chakakosha pakushanda kwekuzvibata pachako. Unyoro hwakakodzera hunobatsira kuvandudza kufambisa uye kuita kwekuvaka kwemutumbi. Kazhinji, iyo chiyero chemvura kusvika kument inodzorwa pakati pe 0.35 uye 0.45. Mvura yakawandisa inogona kukonzera iyo motsi kuti ive yakanyanya kuyerera uye kurasikirwa nayo kuzvimiririra. Mvura shoma kwazvo inogona kukanganisa maitiro ehutsanangudzo yeiyo simende, zvichikonzera kusimba isina kukwana.
3. Maitiro ekuvaka uye mashandisiro ezvekuzviisa wega cinement / dhaka
Kuzvigadzirira simende / mongwe ine zvakanakisa kuzvimiririra, simba uye kusimba, uye zvinoshandiswa zvakanyanya mukuvaka. Maitiro ayo ekuvaka anogonesa kuti awane nzvimbo yakatetepa munguva pfupi, kunyanya yakakodzera pamapurojekiti akaita sevhu uye pasi.
Kuvaka Easy
Sezvo kuzvimiririra kwechisimba / mongwe ine simba rakasimba, maitiro ekuvaka anogona kuzadzikiswa nemakaniki emakanika achisanganisa uye akasarudzika mashandiro asina maitiro akaomarara. Mushure mekunge kuvakwa kwapera, simendi yekuzvikudza inokwenenzvera inogona kukwira pachayo munguva pfupi, kuderedza kupindira kwemanyoro uye kugadzirisa kushanda kwebasa.
Kusimba kwakasimba
Kuzvimiririra simenti / mongwe ine simba rakanyanya rekumanikidza uye kupenga kuramba, uye kunogona kuramba uchikanganiswa panguva yekureba. Uye zvakare, yayo yakaderera hydration hydration maitiro inoita kuti ive yakakodzera kune yakakura-nzvimbo yekuvira, kudzivirira chizvarwa chemaza.
Zvinoshandiswa zvakanyanya
Kuzvimiririra simendi
Iyo formula uye yekusanganisa maitiro ekuzvimiririra coment / mongwe yakaoma kwazvo, inosanganisira iyo chaiyo yekudzora chikamu cheSimende, Aggregate, kuwirirana uye nemvura. Iyo chaiyo chikamu uye yakakwirira-mhando zvigadzirwa zvekushandisa zvinokwanisika zvinogona kuve nechokwadi chekuvaka kwayo kuita uye yekupedzisira mamiriro emhando yepamusoro. Nekuvandudzwa kwezvekuvaka maindasitiri ehukama hwemhando yepasi, musika unodiwa kuti uzvigadzirire simende / dhudzi rekugadzira-rekugadzira richaenderera mberi nekukura, uye tarisiro yayo yekugadzira yakafara. Mune zvinoshanda zvinoshanda, kugadzirisa fomuula maererano nezvinodiwa zvakasiyana zvinogona kurwara zviri nani kutamba zvakanakira uye kupa mhinduro dzakakwirira dzekuvakwa kwepasi.
