Lime-pozzolan esimende: kugadzirwa uye kushandiswa

clinker Pozzolan simende acho ane weupfu fomu tichisunga ehupfumi, zvakavakirwa chiripo yokuvirisa siyana. Weight anowana epurasitiki chivako pamusoro kuonana nemvura uye solidifies pamusoro kuomesa.

kugadzirwa

At kushandiswa zvirimwa akaita kwesuko-pozzolan simende, kugadzirwa kunoda inofanira uzere kutenderera. Kusiyana zvivako izvi maindasitiri ndechokuti vane mupanda nokuda nokugeda rinoshandiswa kuti kukuya uye nokuomesa yokuvirisa. Vanoita sezvo dzinongoitika chicherwa zvinhu - gliezh, diatomite, uyewo zvinoita kushandisa ne-zvibereko simba kugadzirwa.

A muzvizhinji yakawedzerwa zvinhu zviri zvinhu zvakadai, somunhu pozzolan simende. Murwiyo uye kuwanda zvinhu itibatsire uchishandisa unhu. Kushandura solidification nguva panguva ngaakuyire pamusoro gypsum iri akawedzera, mari kwayo kunofanira kuva anopfuura 3% yose inowanwa uremu.

mamiriro

nokugeda zvachose, kuva nzira zvikuru nevanhu kuti mukugadzira kwesuko-pozzolana simende, ane nevamwe chepfungwa ari muchimiro vachigeda clinker pamwe gypsum uye chicherwa vanoshingaira okunze ari inokosha Multi chigayo. Pamberi zvinhu izvi Vanopwanyirwa uye vakauya kuna zvaida mwando dhigiri kuomesa Drum. Zvinokosha kucherechedza kuti kuwedzera nhamba mugove yokuvirisa kunoderedza mari acho.

Lime-pozzolana simende solidification kwacho inonyatsoziva tembiricha kuchinja. At kutonhora kusvika madhigirii 14 musanganiswa yakanga dzinoratidzwa anononoka solidification. The kwacho kunova anomira kana ambient tembiricha iri 5 inegumi. Nokuda kwaizvozvi zvinoomesa zvikuru kushandisa mashoko ari kutonhora mwaka napadare.

Panguva pozzolan esimende vakanzwisisa zvikuru nokukurumidza pane tembiricha yakakwirira uye kunyange kupfuura dzose Portland simende. Kuwedzera chokupika kugadzirwa zvinoriumba, vanogona kuva pasi mimwe kupisa arapwe tembiricha iri kuwanda 80-90 inegumi.

Zvakanakira nekuipira

Pozzolan simende, izvo ehupfumi kubvumira kuti aumbe panguva solidification zvinhu zvakadai karusiyamu hydrosilicate hydroaluminate uye zvakasiyana kushanda duku pane avo yakaumbwa muna kwakajairika esimende rinopa kurwisa kwazvo kuti migumisiro sesaline uye mvura yakachena. Pakati zvazvakanakira zvinokosha kuziva zvinotevera:

• pozzolan samende dzinoratidzwa paumbwe makatsemuka vashoma;
• refu azvipire adhesion kune chesamende chisimbiso zvinhu;
• nyore yokugadzirisa nayo;
• zvakaisvonaka Bonding unhu;
• The pozzolanic muvhenganiswa anoumba mukuru kwazvo kongiri kana dhaka pamwe chete kudyiwa zvinhu uye mamwe marudzi wemisanganiswa.

Asi hazvina pasina zvainovhiringidzawo:

• kudikanwa kushandisa kupfuura gauging mvura;
• chengetedzo refu zvinoderedza basa zvinhu ine.

Zvaunofanira Kuziva

Pasina simende asingaiti chinhu rokuvaka, apo Russia ari mutungamiri kubudisa mashoko aya. Chero zvakasiyana ayo yavo makemikari marongerwo inotungamirwa ndezvaMwari muchikwata che silicates, kuti chirungiso aripo ari murwiyo muchimiro nesilicon dioxide. Sezvikonzero esimende clinker makabuda iyo wakagadzwa kwesuko nevhu, zvekare vachiridzira. Diatomaceous pasi anoita sechinhu. Akaumba muzana kugadzirwa uye kushandiswa esimende guruva nokuda kwenguva refu uchinzwa anokonzera bronchitis kukura uye zvisingawanzoitiki kacho - pneumoconiosis, akapa zvakawandisa nesilicon yakasviba layer iyo unotora munhu pozzolanic simende.

Silicosis chinhu kwazvo chimiro pneumoconiosis uye rinonyanya vawana panguva vanoshingaira kukura engineering migodhi indasitiri nokuti chokuti kushanda nziyo kunokanganisa vakawanda Goldstone guruva. The chirwere chinonyanya nevakawanda vanhu chokuita kubudiswa girenayiti, pave tunnels, kuvakwa zvedongo uye refractory yeimwe.

Dzimwe nzira inoshandiswa

Pozzolan simende, vane ehupfumi kuvimba acho, unogona kuitwa kwete chete pane miti asiwo pakuvaka nzvimbo pachavo kushandisa nokugeda-nokuomesa zvivako. Vari yaoma chicherwa zvokuwedzera, tiri pasi uye hwakakanyiwa hombe, zvingadarowo mawa nokugeda pakati zvokubikisa. Izvi zvinoderedza motokari kuzara, zvifambiswe chete clinker uye chicherwa zvinhu pachavo anobudiswa pakuvaka nzvimbo. Pakati zvakanakira yakadaro nzira chinofanira kuzivikanwa mukana kuchinja murwiyo dzichangobva akaita zvinhu pamwe fillers. Asi kushandisa unyanzvi zvivako anoruramiswa chete bhuku guru rokuvaka.

Pozzolan simende: kushandiswa

The kushandiswa nevakawanda zvinhu vawana pakasikwa zvakasimbisa kongiri uye kongiri zvinhu pasi pevhu uye pemvura kushandiswa, iyo pamwe chete sulfate uye mvura yakachena. Inogona kushandiswa zvinwiwa uye STRUCTURAL okunze, runyararo iyo vakuru kwevari mwando inozivikanwa. Kazhinji kushandiswa hydraulic ouinjiniya zvakagadzirwa rinoumbwa vnutrimassivnogo kongiri.

Kushandiswa kongiri hurongwa yenyika shoma nokuda yakaderera chando nemishonga unhu, kunyanya pamwe proviso mhepo solidification. Izvi zvinobva kutsanya nokuomesa, rinogona kumisa chirongwa solidification uye kungaita kuti chinokosha shrinkage. Uyewo pamamiriro kusikwa STRUCTURAL zvinhu pozzolan simende, kana vari kushandiswa pasi nguva nenguva thawing uye nechando, nokuomesa uye hydration.

simba

Pozzolan simende sezvamunoita, zvivako, mafomu izvo zvinopa simba pachena pamusoro prefabricated okunze, ndiye hunogara, zviri kukonzerwa chitsama calcium silicate aumba. Nokuti zvinhu dzinoratidzwa kuwedzera refu nesimba nokuda rutapudzo ari zvachose mambure kurema samende, zvose dzinovepo yokuwedzera ingredients. Kuwedzera kuomesa akacherechedza hydrate nokuda kuita kuti karusiyamu oxide uye kushingaira silica, kunoguma kupfuma simba rakafanana nemamwe simende grout. Naizvozvo, hurefu kugara pfupa nyoro ezvinhu.

Water chinodikanwa

Pozzolan simende, iyo yakavakirwa diatomite uye Tripoli, kunoratidzwa wakawedzera mvura kudiwa, zvichitungamirira nomumugwagwa kwaitora nguva nenguva yokupedzisira solidification. Kuumba samende slurry zvaida mari emura kunowedzerawo zvichienderana zvicherwa zvinoshingaira okunze. rutapudzo Its ari kuchengetwa pamberi yokuvirisa vari Kuronga tuff uye njanji.

Kuwedzera mvura kwokudiwa iri chisingadiwi nokuti hunoita kuti mukuru kudyiwa ichi mhando esimende zvichienzaniswa nedzimwe. Kuwedzera Nhunzi dota haachinji chitsama emura vanoenderana nokusanganisa. Inogona hwakakanyiwa zvose chesamende kunovhengana uye pachawo simende. The chatingatevedzera acho haina ipfupi kunyange kana padurunhuru kuchatsiviwa chikamu.
