Khoom Description

Dab tsi yog expanding cement?

Expanding cement yog hais txog cov khoom siv hydraulic cementitious ua los ntawm kev sib tsoo Portland cement clinker, ib qho tsim nyog ntawm gypsum thiab ib qho kev nthuav dav ua ke.

Expanding cement yog ib hom tshwj xeeb ntawm hydraulic cement uas nthuav me ntsis thaum lub sij hawm teem thiab hardening, yog li compensating rau qhuav shrinkage thiab tiv thaiv tawg. Tsis zoo li zoo tib yam Portland cement (OPC), uas shrinks thaum lub sij hawm kho, expansive cement undergoes tswj nyob rau hauv expansion los txhim kho durability thiab structural kev ncaj ncees.

Hom kev nthuav dav cement

① K-Type (calcium sulfoaluminate-raws li): Siv rau hauv grouts thiab kho, hom no muaj kev nthuav dav.

② M-zoo (Alumina + Txiv qaub): Siv rau hauv pre-stressed pob zeb, hom no nthuav tawm siab thaum ntxov.

③ S-Hom (High Sulfate): Rau cov pob zeb uas them nyiaj rau qhov shrinking.

Expanding cement manufacturing txheej txheem

1. Cov khoom siv raw

Clinker rau Portland cement (60-80%)

Cheebtsam rau kev nthuav dav (10-30% sulphoaluminate / clinker lossis ntxiv raws li calcium oxide)

Gypsum (5-10% rau kev teeb tsa)

2. Kev tsim khoom ntawm Clinker

Sulphoaluminate nthuav clinker kiln sintering (1250-1350 degree)

Hloov cov muaj pes tsawg leeg (kev nthuav dav yog tswj los ntawm siab C₄A₃).

3. Sib tov thiab sib tsoo

Co-clinker hauv av nrog kev pab ntxiv thiab gypsum

Fineness: Qhov zoo tshaj plaws reactivity yog 400-450 m² / kg.

4. Kev tswj kom zoo

Raws li ASTM C845 cov txheej txheem, kev sim nthuav dav (0.1-2% hauv 28 hnub)

Compressive zog: 20-50 MPa, nyob ntawm kev siv.

Yog tias koj xav tau cov ncauj lus kom ntxaws cov cuab yeej teeb tsa ntawm tag nrho cov nroj tsuag, thov xa peb cov lus nug. Peb yuav muab ib daim ntawv teev kev teeb tsa thiab cov lus hais raws li koj xav tau ntau lawm.

Kev nthuav davckevmanufacturing process adaim ntawv thov

Cement uas expands silicate:Nws yog feem ntau siv hauv kev tsim cov pob zeb tsis muaj dej tsis zoo thiab mortar. Nws tuaj yeem siv rau kev sib koom ua ke thiab kho cov haujlwm, nrog rau kev sib koom ua ke ntawm cov khoom thauj tog rau nkoj, nchuav tshuab hauv paus, thiab cov tsev txhawb nqa. Txawm li cas los xij, nws tsis tuaj yeem siv hauv dej engineering qhov twg sulfate yaig tshwm sim.

Micro-expanding cement nrog tsawg tshav kub:Nws feem ntau yog siv rau loj - ntim pob zeb, pob zeb uas muaj cua sov qis ntawm cov dej, thiab cov pob zeb uas xav tau kev pab cuam shrinkage. Tsis tas li ntawd, nws ua haujlwm zoo rau tej yaam num uas yuav tsum tau impermeable thiab resistant rau sulfate yaig.

Sulphoaluminate expanding cement:Nws yog feem ntau siv rau hauv cov phiaj xwm pob zeb uas xav tau impermeability thiab shrinkage them, nrog rau kev sib xyaw ntawm cov pob zeb.

Cement uas stresses nws tus kheej:Tus kheej-txhawb cov kav dej muaj zog thiab lawv cov khoom siv tseem ceeb yog nws daim ntawv thov.
