Cement yog qhov sib tov pub dawb uas muaj cov clinker. Feem ntau gypsum los yog nws cov derivatives thiab ntau yam tshwj xeeb additives kuj ntxiv. Thaum ua ke nrog dej, nws hloov mus rau hauv ib tug mushy loj, uas tom qab solidifies nyob rau hauv cov huab cua thiab hloov mus rau hauv ib tug muaj zog, nyuaj pob zeb.
Portland MAAs (M500-cement) yog hydraulic binder uas aluminate thiab calcium silicate predominate (txog 70-80%). Nws yog dav siv nyob rau hauv yuav luag txhua lub teb chaws thiab occupies ib tug ntawm cov thawj txoj hauj lwm nyob rau hauv lub tsev cov ntaub ntawv lag luam ntawm lub CIS thiab Ukraine. Nws yog siv nyob rau hauv kev tsim kho vaj tse peev, hauv kev tsim khoom, thiab lwm yam.
M500 cement: scope
hom cement no yog siv rau cov haujlwm hauv qab no:
- Kev tsim kho ntawm monolithic reinforced pob zeb.
- Kev tsim kho txoj kev.
- In the airfield construction.
- Rau cov khoom hauv pem teb, hydraulic qauv hauv dej tshiab.
- Rau nrawm demoulding pob zeb ua haujlwm.
- Kev tsim cov hauv paus, hauv pem teb slabs thiab kab teeb hauv kev tsim kho vaj tse.
- Kev tsim cov mortars rau lub tsev plastering.
Ntse
M500 cement yog nrov heev thiab xav tau. Nws muaj cov yam ntxwv hauv qab no:
- Zoo zog. M500-cement yog qhov muaj zog tshaj plaws ntawm cov cement sib tov uas siv rau hauv kev tsim kho. Nws yog feem ntau siv rau hauv kev tsim cov kav dej txuas ntxiv, txoj kev pavement, kev txhawb nqa high-voltage, paving slabs, thiab lwm yam.
- Frost resistance. Ua tsaug rau cov cuab yeej no, nws yog resistant rau alternate freezing thiab tom qab thawing. Txawm li cas los xij, cov cement ntshiab tsis muaj cov khoom zoo li no, lawv tau muab rau nws los ntawm kev hloov kho tshwj xeeb ntxiv. Yog tias tus qauv tsim kom muaj kev tiv thaiv Frost, nws yog hydrophobic M500 cement uas tau xaiv.
- Corrosion kuj. Tsis raug rau qhov tsis zoo ntawm qhov chaw sab nraud. Pozzolanic qib muaj qhov ua haujlwm siab rau corrosion. Nws yog siv rau kev tsim kho ntawm underwater thiab underground lug.
- Ntxhais tau dej.
Type of cement M500
Portland cement yog cov hauv qab no:
- ceev ceev;
- hydrophobic;
- kev;
- plasticized;
- nrog nruab nrab exotherm;
- sulfate resistant;
- nrog cov organic surfactants;
- dawb thiab xim.
KevcementM500
Cement muaj qhov sib txawv ntawm hom thiab ntau ntawm cov khoom ntxiv. Cov ntawv luv "PTS" lossis "M" yog hom npe. Tus lej 500 yog qib ntawm nws lub zog. Qhov no txhais tau hais tias nyob rau hauv daim ntawv tiav cov khoom muaj peev xwm tiv taus qhov hnyav ntawm 500 kg ib 1 cm 2thiab tsis tawg. Kev sib cais tsis nyob ib sab ntawm lub hom (qhia los ntawm tsab ntawv "D") qhia txog qib ntawm cov ntxhia ntxiv hauv feem pua. Piv txwv li, "D20" txhais tau hais tias cov cement muaj 20% active additives. Cov khoom siv ntxiv hauv cov cement yog siv los txhim kho cov yam ntxwv thev naus laus zis (nce hauv corrosion kuj, plasticity, lub zog yam ntxwv).
Tseem muaj ntau yam ntawm nws nrog cov khoom tshwj xeeb. Lawv raug cim nrog cov ntawv luv luv:
- "B" - ceev ceev.
- "H" - normalized cement (raws li clinker).
- "SS" - sulfate resistant.
Ntau hom cement, qhov thiab lub hom phiaj
M500 D0 cement yog siv rau hauv kev tsim kho kev lag luam hauv kev tsim cov pob zeb tseem ceeb thiab cov pob zeb ua vaj tse, uas yuav tsum tau nce ntxiv (piv txwv li, durability, dej tsis kam, Frost resistance).
M500 D20 cement yog siv rau hauv kev lag luam, kev ua liaj ua teb thiab thaj chaw tsim kho rau kev tsim cov pob zeb ntxiv, cov hauv paus, kab teeb, pem teb slabs, rau kev tsim cov vaj tse pob zeb, masonry, plastering thiab lwm yam kev kho thiab kev tsim ua haujlwm.. Hom cement no yog waterproof, Frost-resistant, muaj ib tug txocorrosion kuj piv rau cov pa cement.
Cement M500 D20-PL muaj cov ntxhia ntxiv. Nws yog plasticized.
Raws li kev ntim khoom, muaj cov cement hauv lub hnab (M500) ua los ntawm peb-txheej ntawv lossis ntim yas (lub hnab loj). Yas tiv thaiv zoo los ntawm ya raws, yog heev resistant rau ntau yam kev puas tsuaj. Koj tuaj yeem yuav cov cement hauv ntau.
Qhov hnyav ntawm pob uas cov cement M500 muag yog 50 kg. Qhov no yog tej zaum qhov kev xaiv ntim khoom nrov tshaj plaws.
Yog li, cov khoom siv hauv tsev no yog qhov zoo heev thiab tus nqi nruab nrab.
