UAA Expanding Agent

Khoom Taw Qhia
Thaum ntxov, anhydrous calcium aluminate feem ntau yog siv los ua qhov chaw nthuav dav. Hauv nruab nrab theem, bauxite tau siv los ua qhov chaw nthuav dav, uas muab cov teebmeem kev nthuav dav ruaj khov. Ordinary pob zeb zoo li tawg vim shrinkage, feem ntau ua rau to, uas txo nws cov functionality thiab durability. Los ntawm kev ntxiv ib qho nyiaj ntawm UEA (urea-expanded agent) rau cov pob zeb zoo tib yam, expansive crystalline hydrates tsim compressive kev nyuaj siab, uas pab compact cement hydration khoom xws li ettringite, tsim micro-expanding pob zeb. Qhov no expansion quab yuam thaum teeb tsa densifies lub pob zeb. UEA-H expansive agent tau tsim nyob rau hauv 1986, tom qab ntawd los ntawm kev txhim kho tus neeg sawv cev qis-alkali expansive nyob rau hauv 1993 thiab nws nce qib nyob rau hauv 1994. Lub Ministry of Construction tau teev cov low-alkali expansive agent (UAA-H) raws li ib tug tseem ceeb project rau nce qib hauv xyoo 1994. Los ntawm kev kho cov mis kom txo alkalinity, nws tsis txhob muaj alkali-tag nrho cov tshuaj tiv thaiv hauv cov khoom cement thiab optimizes lawv kev ua tau zoo. Cov qauv khoom: JC476-2001. Kev koom tes tseem ceeb rau kev tsim khoom siv thev naus laus zis!

Anti-Leakage Txoj Cai

Tiv thaiv Shrinkage Cracking
Thaum UEA expansive tus neeg sawv cev ntxiv rau cov cement pob zeb, ntau cov expansive crystalline hydrates yog tsim tom qab sib tov nrog dej. Lub compressive kev nyuaj siab uas ua los ntawm cov hydrates tuaj yeem ua rau cov kev ntxhov siab tensile los ntawm kev ua vaj tse shrinkage, yog li tiv thaiv los yog txo qhov tawg thiab ua kom cov pob zeb denser.

Tsim cov tshuaj Prestress
Nyob rau hauv cov pob zeb muaj zog nrog UEA expansive tus neeg sawv cev, lub zog nthuav tawm los ntawm UEA ua rau muaj zog tensile nyob rau hauv cov hlau tuav, thiab cov tshuaj tiv thaiv quab yuam compresses lub pob zeb, tsim ib tug prestress ntawm {{0}}}.2 rau 0.7 MPa nyob rau hauv lub steel tuav. Qhov no ua rau tib yam kev ua haujlwm zoo li pre-stressed steel tuav.

Tsim cov tshuaj muaj zog
Thaum cov pob zeb lossis mortar nrog expansive tus neeg sawv cev yog tag nrho txwv externally, expansion quab yuam ntawm UEA ua nyob rau hauv, thiab ettringite crystals tsis tu ncua puv lub pores. Qhov no ua rau lub zog siab, tsis yog shrinking, ntom pob zeb thiab mortar, exerting tib yam li cov neeg kho tshuab siab.

Thaum Ntxov muaj zog: Qhob nrog UEA low-alkali expansive agent qhia lub zog thaum ntxov piv rau cov pob zeb zoo tib yam.

Waterproof Qib: 1-2 lub sij hawm siab dua li cov pob zeb zoo tib yam.

Kev siv tseem ceeb

Kev tsim kho hauv av: Underground chaw nres tsheb, warehouses, tunnels, mines, civil tiv thaiv tej yaam num, underground neeg taug kev txoj kev, tshuab shafts.

Cov qauv dej cia: Cov dej tso tsheb hlau luam, cov pas dej da dej, cov kav dej, cov tso tsheb hlau luam, cov thawv loj, cov nplej silos, cov roj tso tsheb hlau luam, cov qhov tsua rau khaws cia, thiab lwm yam.

Prefabricated Cheebtsam: Thauj tog rau nkoj pob qij txha nyob rau hauv thav duab qauv, pipeline pob qij txha, grouting cov ntaub ntawv rau post-tensioned prefabricated Cheebtsam, backfilling ntawm kev tsim kho pob qij txha, pob zeb foundation grouting cov ntaub ntawv.

Cov tsev tseem ceeb uas yuav tsum tau muaj kev sib tsoo thiab kev zoo nkauj: chaw ntau pob, sculptures nroog, monuments, tsev cia puav pheej, tsev so, thiab lwm yam.

Optimal Dosage
Raws li txoj cai, UEA nthuav dav tus neeg sawv cev tuaj yeem ntxiv rau tsib hom cement. Txawm li cas los xij, txhawm rau ua kom cov pob zeb zoo, zoo tib yam Portland cement nrog qib 32.5R lossis siab dua thiab slag cement yuav tsum tau siv. Rau pozzolanic cement thiab ya tshauv cement, kev sim yuav tsum tau ua.

Expansion Agent Dosage

Cov xwm txheej siv

Cement Qib Xaiv: Siv 32.5R lossis siab dua li Portland cement thiab slag cement rau kev ua tau zoo tshaj plaws.

Mixing Sijhawm: Yog tias siv lub tshuab sib tov, txuas lub sijhawm sib xyaw kom ntev li 30 vib nas this piv rau cov cement pob zeb; yog tias siv lub tshuab ua kom poob nws tus kheej, txuas lub sijhawm ntev dua 1 feeb. Kev sib tov yuav tsum txuas ntxiv mus kom txog thaum sib tov ua tiav.

Kev Thauj Pob Zeb thiab Compaction: Cov txheej txheem tib yam li cov cement pob zeb zoo tib yam, tab sis yuav tsum tau saib xyuas ntau dua hauv vibrating lub pob zeb tsis muaj dej kom ntseeg tau tias nws yog compacted tag nrho.

Kev saib xyuas tom qab qhov chaw: Tom qab pouring, lub pob zeb yuav tsum tsis txhob raug tshav ntuj ncaj qha thiab yuav tsum tau them nrog straw mats. Tom qab hardening, cov neeg ua haujlwm tshwj xeeb yuav tsum tswj kev kho, kom ntseeg tau tias cov pob zeb tseem nyob hauv qhov chaw ntub dej tsawg kawg 14 hnub. Kev siv cov tshuaj tua kab mob tau txais txiaj ntsig zoo dua.

Sau ntawv

Kev sib xyaw tsim rau kev ua vaj tse nrog UEA expansive tus neeg sawv cev yog tib yam li cov pob zeb zoo tib yam, tab sis cov ntsiab lus ntawm cov cement yam tsawg kawg nkaus ib lub cubic meter yuav tsum tshaj 300 kg.

Qhov sib ntxiv ntawm UEA expansive agent (E) yog xam raws li qhov feem pua ​​​​ntawm cov cement, piv txwv li, E / (C + E), qhov C yog cement thiab E yog UEA expansive agent.

Lub sij hawm sib tov yuav tsum tau ncua ntev li 30 vib nas this thaum siv cov khoom sib tov thiab tsawg kawg yog 1 feeb rau cov khoom sib tov rau nws tus kheej.
