Expansive Agents reacts nrog dej thiab cement minerals, tsim calcium sulfoaluminate, calcium hydroxide, ferric hydroxide, thiab lwm yam., ua rau ntim expansion. Qhov no ua rau muaj kev ntxhov siab nyob rau hauv qhov txwv ntawm cov hlau tuav thiab cov qauv uas nyob ib sab, tiv thaiv cov kab nrib pleb, them nyiaj rau shrinkage, absorbing hydration heat, thiab filling capillary voids kom cov pob zeb ntom ntom thiab impermeability.
Khoom nta:
Tsawg Alkali Cov ntsiab lus:Zoo tiv thaiv alkali-aggregate cov tshuaj tiv thaiv hauv pob zeb.
Tsawg Dosage, Zoo Expansion Performance:Tau tshaj cov cement thiab additives.
Non-corrosive rau hlau:Tsis muaj kuab paug rau dej, zoo sulfate kuj.
Cov lus qhia siv:
Mix Design:Kev sib xyaw tsim ntawm cov pob zeb nrog HCEA cov neeg ua haujlwm siab nthuav dav yuav tsum ua tau raws li cov kev qhia thiab kev tsim kho kev ua haujlwm kom muaj zog, nthuav dav kev ua haujlwm, impermeability, thiab durability.
Expansion Dosage:Raws li qhov yuav tsum tau txwv kev nthuav dav tus nqi teev tseg hauv kev tsim, siv cov ntaub ntawv engineering los txiav txim siab npaum li cas los ntawm kev sib xyaw tsim kev sim.
Pom zoo Dosage:
6-10% ntawm cov ntaub ntawv cementitious (sib xyaw sab hauv):6-8% rau cov pob zeb shrinkage-compensated, 8-10% rau cov khoom siv tom qab cam khwb cia, expansion reinforcement bands, thiab kev tsim kho sib koom ua ke.
Kev tsim kho:Xyuas kom lub shrinkage-compensated qhob yog npaj raws li cov kev cai tsim mix, thiab xyuas kom meej npaum li cas ntawm tus neeg sawv cev expansive.
Mixing Sijhawm:Txuas lub sijhawm sib xyaw ntawm qhov chaw sib xyaw ua ke los ntawm 30 vib nas this piv rau cov pob zeb zoo tib yam los xyuas kom meej qhov sib xyaw ntawm tus neeg sawv cev nthuav dav, xis mas, thiab dej reducer, txhim kho homogeneity.
Daim ntawv thov teb:
Underground Structures:Xws li subways, underground chaw nres tsheb, tunnels, mines, pej xeem tiv thaiv tej yaam num, neeg taug kev underpasses, tshav dav hlau, thiab lwm yam.
Tsev Pas Dej:Cov pas dej da dej, cov kav dej phwj tuaj, cov kav dej, cov roj tso tsheb hlau luam, cov kav dej tsis zoo ru tsev mortar noo noo thaiv, thiab lwm yam.
Prefabricated Cheebtsam:Anchoring pob qij txha ntawm thav duab cov qauv, cov kav dej sib txuas, rov qab ntawm cov pob qij txha tsim, pob zeb hauv paus grouting cov ntaub ntawv.
Cov khoom siv cement:Cement pressure pipes, waterproof ru tsev panels, thiab lwm yam.
Kev loj Pavements:Choj pob zeb nto, culverts.
Crack thiab Seepage Prevention:Txhua yam kev tsim vaj tsev thiab cov khoom cement yuav tsum tau tawg thiab seepage tiv thaiv thiab sib koom ua ke.
