Kuumba Dry Mixtures A mhinduro kubva

Cement - sokurwarirwa bhainda pamusoro inorganic hunhu. Chimwe chedzidziso uye chikuru zvokuvakisa. Nokuwedzera mvura kana aqueous munyu zvinogadzirisa, kana zvimwe mvura, pova mapurasitiki musanganiswa iyo gare gare anoomesa kuumbika yakasimba. Pachirehwa chivako zvinhu kuitira kugadzira kongiri uye siyana mumaturi. Hazvina unopfuura zvakasiyana nezvimwe zvicherwa kunyorerana zvinhu (madota kana gypsum) kuti zvigare zvachose kunze. On nesimba zvinhu yakakamurwa mavanga, varehwa pauwandu 100 600, kureva simba compressive 10 - 60 MPa. giredhi Material 600 anonzi "uto" nokuda kwesimba ravo pachavo uye munda kushandiswa (nokuti kuvakwa kwezvivako mauto), uye tinorasikirwa zvakawanda muchiso 500. Nhasi, mashoko aya anonziwo rakakamurwa makirasi (30 kusvika 60), izvo anoratidza simba compressive (MPa). Musiyano mukuru kubva pezvitsiga kuti kurwisa hakusi zvinoreva uye anokumbira hapana asingasviki 95% rakanaka, kureva, 95 kubva 100 mitemo vanofanira kusangana kirasi.

With maererano kuti kugadzirwa, samende anogadzirwa pachishandiswa yakaisvonaka kwazvo nokugeda kuti gypsum uye clinker. Brick uyu kana Zvaizobuda homogeneous calcining asati sintering ari homogeneous nezvakavhenganiswa, iro rinoumbwa ivhu murwiyo pamwe nani karusiyamu silicate uye madota. Kana vachigeda clinker kupotsera gypsum kuti kuchinja nguva ichaitika nokuomesa, kusvikira 15% chicherwa dzichipfekeka yokuvirisa (pyrite, cinders, flue guruva, jecha uye zvichingodaro. PA) kuitira kuvandudza zvimwe zvivako, uye richikwidibira mari kutanga zvinhu. Vachiridzira yokutanga musanganiswa rinoitwa panguva tembiricha kuti 1470 ° C imwe ya 2 - 4 awa refu inokosha yamavira pamwe Integrated kupisa Exchange mano zvakagadzirirwa kuti zviite kwetunhu yakakodzera simende chizvaro zvicherwa.

Zvinozivikanwa kuti simende - ichi yemavara mhando, pasina chinova chikamu nhasi chivakwa. Just sei zvakanaka zvikuru zvinodiwa akavaka kosi, zvinoenderana zvakananga uwandu mubereko, kunyanya mugadziri wacho unhu kuvaka zvinhu. Pasinei ingangodaro zvisizvo kuti yepamusoro simende muvhenganiswa inofanira kukosheswa insanely zvinodhura, haisi kunodiwa kuva mutengo kwirirei. Zvino, pane imwe nguva inokosha, vanogadzira Distributors vari kuedza kuita rastsenochnuyu hurongwa nani. kune mativi, kuti tirambe vade uye makwikwi, uye unhu dzimwe nguva haana muduku nezvinodiwa kuEurope, kunyange ari yepamusorosoro kugadzirwa kuderera kunyange kupfuura Havakoshi. Panotova zvakasiyana samende nezvakavhenganiswa, vane anokosha zvinhu. muvhenganiswa Izvi runotaurwa nomumwe zviratidzo: B - nokukurumidza nokuomesa; C - Sulfate uye H - musanganiswa, kunobva ibwe sezvamunoita normalized (normalized).

Early simba samende dzinoratidzwa kukura basa mumweya kwokutanga nguva nokuomesa. Akashandisa kunyanya nokuda kwezvifananidzo zvaAtemisi Precast kongiri zvinomera uye zvigadzirwa. High zvokuimba rakavimbika pakutanga ari kudurura zvinotsanangurwa zvakanaka uye chicherwa Zvinoumba clinker unaku yokuvirisa pakukura uye fineness. Sulphate kana musanganiswa Portland simende sulfate kubudikidza panotaurwa zvavo Portland simende ane soro kuramba sesaline mvura, anononoka batira zvakanyanya uye yakakwirira chando nemishonga. Concrete kufamba uye yendege tichigadzira, bhiriji zvivako vanofanira kushandisa simende muvhenganiswa unoitwa pachishandiswa normalized clinker.
