Izvo zviyero zvakakwana zvekrete zvinoenderana nemhando yaro

Dombo rekugadzira, iro rakasikwa nekusanganiswa nemvura, kusunga mumiririri uye aggregates (marara, jecha kana girafu), uyezve kumwe kusimbisa, kunonzi konkrete.

Sezvo chivakwa chekuvaka chakatanga kushandiswa munguva dzekare, krete, iyo yakarongeka yakanga yakave yakasiyana zvakanyanya kubva ikozvino. Paiva nenguva iyo yakambomira kwechinguva, asi muzana remakore rechi19 idzva remadzimai anosungiridza hydraulic, akadai sa portland samende, yakagadzirwa, uye ikrete yakave yakakurumbira mukuvaka. Mumakore makumi matanhatu ezana remakore rechina. Inyanzvi yekushandiswa kwesimenti yakagadziridzwa, simba rekodha rakawedzera uye rakashandiswa senhengo huru yekrete. Panguva ino, chigadzirwa ichi ndechimwe chezvinhu zvakakosha zvikuru zvekuvaka izvo zvinoshandiswa munharaunda dzose dzekuvaka kwemazuva ano.

Kubvuma uku kwaakagamuchira nekuda kwezvinhu zvinotevera:

• Zvimwe zvakasiyana-siyana zvinowanikwa nekuda kwekusiyana kwekushandiswa kwematombo emhando uye zvinyorwa zvinyorwa uye zvakasiyana-siyana zvemuviri-makemikari uye magetsi processing;
• Kusununguka kwebasa pamwe nekrisiti yakasanganiswa, iyo ine purasitiki yakakwirira uye inokubvumira kubereka maitiro akasiyana-siyana uye masimba ezvigaro, zvakasimba-kuvaka zvivako;
• Unyanzvi hwokugadzirisa zvachose nzira yekushanda nekrete;
• Economy, sezvo ivhu rayo 80-90% yakazara nematombo emagetsi ekugadzirwa kwemunharaunda.

Kugadzirwa kwepamusoro yekhonkrit mix kunokwanisa chete kana iwe uine ruzivo rwe teknolojia, unyanzvi hwokusarudza zvinhu zvehumwe hutano uye kukwanisa kuverenga chiyero chavo, kuwana nzira yekuisa, kutengesa uye maitiro ekugadzirira kusanganiswa.

Nekugadzirwa kwezvivako zvakasiyana-siyana zvehujini, marudzi akasiyana ekrete anoshandiswa ( zvichienderana nemunda wekushanda). Pane zvinhu zvakasiyana-siyana zvinoshandiswa pane zvinyorwa izvi: hukuru hunokwana hwekrete, simba rayo, rudzi rwebinder, chinangwa uye frost resistance. Izvo zvikamu zvakakosha ndezvekuwedzera kwekuyera. Saizvozvowo kune iyo, mahedheni anonyanya kujeka, kuedza, kurema uye kunyanya kuoma.

1. Mukutanga - nhamba inokosha yemasero mashoma uye maduku anenge 1-1.5 mm muhukuru, saka inonziwo cellular. Iko kuyerwa kwekakiti yemakiromita mita ine inenge 500 kg. Sezvo mutemo, rudzi urwu runoshandiswa sekupisa-kuvhara.

2. Mapapu. Mhando iyi inosanganisira iyo yezvinhu zvisingasviki zvigadziriswa zvinoshandiswa sezadza - claydite, tuff, shellfish, kana kuti hapana anozadza zvinoshandiswa zvachose, uye zvinoputika zvinowanikwa-kerikisi yakadzika, mhito yekrete, nezvimwewo. Kurema kwakakwana kwekrete mu cubic mamita 500-1800 Kg. Iyo yakawanda yakaumbwa isuva - kusvika kune 600 kg. Nyaya yakadaro inowanzoshandiswa kuita zvivako zvekuvaka.

3. Mumatanho akaremara mashoma-mashoma mashoma anozadza - marara uye akavezwa mabwe. Rimwe cubic mita inorema kusvika 1800-2500 kg. Iri bhuku rine 1150-1300 kg yematombo kana mabwe akapwanyika, 600-750 kg yejecha, 250-450 kg yementi, 150-200 maita emvura. Konti yakakura ndiyo yakashambadza uye inoshandiswa munzvimbo dzakawanda dzekuvaka.

4. Zvikwereti zvakanyanya zvinorema zvinosanganisira barite, magnetite uye mamwe marudzi ematehwe emarara. Izvo zviyero zvakakwana zvekrete mubhuku re 1 cubic meter rinogona kubva pa 2500 kusvika 3000 kg. Icho chikuru chezvikamu zvehuwandu hwehuwandu hwahwo ndechekubatanidzwa kukuru. Rudzi urwu rwekrete runoshandiswa kunyanya mukugadzira zvivako zvinodzivirira paAEC.

Kuverenga cube yekrete, usakanganwa kuti zvikamu zvayo zvinogona kunge zvakasiyana zvakasiyana. Semuenzaniso, yakanaka-grained aggregate inorema kudarika yakawanda yakawanda, uye ganda jecha rinopenya kupfuura jecha rorwizi.
