Kev tsim khoom thiab kev siv cov pob zeb Expansion Agent hauv Reinforced Concrete
Nyob rau hauv tus txheej txheem ntawm kev teeb tsa thiab hardening ntawm cov pob zeb, cov khoom sib xyaw uas nthuav cov pob zeb los ntawm cov tshuaj lom neeg yog hu ua expansion agent. Cov neeg sawv cev nthuav dav tuaj yeem muab faib ua ob hom raws li lawv qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv hauv cov pob zeb: cov neeg ua hauj lwm shrinkage compensatory uas tsim kom muaj kev nthuav dav me me kom txo tau cov qhob shrinkage; expansion cov neeg ua haujlwm uas tuaj yeem ua rau pob zeb nthuav dav los ua kom muaj kev ntxhov siab rau tus kheej ntau dua nyob rau hauv kev txwv ntawm steel tuav. tus neeg sawv cev. Lub pob zeb tsim los ntawm tus neeg sawv cev nthuav dav tuaj yeem muab faib ua peb hom raws li qhov nthuav dav zog qib thiab daim ntawv thov: compensating shrinkage qhob (σ=0.2~0.7Mpa); filling expansion pob zeb (σ=0.5 ~ 1Mpa) thiab nws tus kheej-stressing qhob (σ= 2). .
Cov pob zeb nthuav dav feem ntau ntxiv nrog qee cov ntaub ntawv uas nthuav dav hauv ntim tom qab hydration, thiab cov ntsiab lus ntawm cov ntaub ntawv no muaj nyob hauv cov pob zeb nws tus kheej, yog li nws yuav tsis ua rau kev ua tau zoo ntawm cov pob zeb.
