Kev tshuaj xyuas cov yam ntxwv tseem ceeb ntawm cov cement pam

Daim pam cement, ua ib yam khoom siv hauv tsev uas hloov pauv tas li, tau nyiam ntau tus neeg saib xyuas hauv kev tsim kho vaj tse vim nws cov yam ntxwv tshwj xeeb thiab kev siv dav.

1. Nws lub ntsiab lus tseem ceeb yog nyob rau hauv cov txheej txheem kho kom tsis tawg, uas tau txais txiaj ntsig los ntawm nws cov khoom siv sib xyaw ua ke uas muaj fiber ntau ntxiv rau sab hauv. Thaum lub pam cement raug tso, tsuas yog xav tau dej yooj yim xwb, thiab cov dej molecules sai sai nkag mus rau hauv lub network fiber, ua rau cov tshuaj tiv thaiv cement hydration, ua rau cov khoom khov thiab tsim nyob rau hauv situ, tsim cov qauv ruaj khov thiab ruaj khov. Hauv cov txheej txheem no, kev ntxiv cov fibers zoo txhim kho qhov tsis kam ntawm cov khoom thiab ua kom ntseeg tau tias cov qauv ruaj khov tuaj yeem tswj tau txawm tias nyob rau hauv qhov chaw nyuaj siab.

2,. Thaum siv rau kev tiv thaiv ntawm tus dej ntws thiab cov kav dej ntws, daim pam cement qhia tau tias nws zoo tshaj plaws. Nws muaj peev xwm haum rau thaj chaw nyuaj, txawm tias nws yog ntug dej ntws lossis hauv qab ntawm tus dej uas xav tau dej ntws zoo, nws tuaj yeem yooj yim tswj nws. Thaum khov kho, daim pam cement yuav raug hloov mus ua ib txheej tiv thaiv muaj zog thiab ruaj khov, uas tuaj yeem tiv taus dej thiab dej ntws, tiv thaiv kev ruaj khov ntawm av, txo cov dej thiab av ntws, txhawb kev ntxuav dej ntuj thiab tswj kev sib npaug ntawm ecological.

3. Qhov zoo tshaj plaws yog tias cov txheej txheem tsim cov cement pam yog qhov yooj yim thiab ua haujlwm tau zoo heev. Piv nrog cov txheej txheem tsim kho ib txwm muaj, nws tshem tawm cov kauj ruam tsis zoo xws li kev tsim cov formwork, kev nchuav pob zeb thiab kev saib xyuas, ua rau lub sijhawm tsim kho luv dua thiab txo cov nqi tsim kho. Tsis tas li ntawd, cov cement pam kuj muaj kev ua tau zoo rau ib puag ncig. Nws tsim cov khib nyiab tsawg dua thaum lub sijhawm tsim khoom thiab tsis tshua muaj kab nrib pleb tom qab khov, uas txo qhov xav tau kev saib xyuas thiab kho tom qab. Nws yog qhov kev xaiv zoo tshaj plaws raws li lub tswv yim ntawm lub tsev ntsuab. Hauv kev xaus, cov cement pam yog qhov tsis ntseeg tias yog "khoom cuav" hauv cov haujlwm txuag dej niaj hnub thiab kev tsim kho pej xeem, thiab maj mam dhau los ua qhov sib txawv tshiab hauv kev txhim kho kev lag luam.
