10 hom kev ua vaj tse nyob hauv kev tsim kho nrog kev pab cuam tshuam

Cov khoom siv ua vaj tse yog ib qho khoom siv hauv tsev uas tuaj yeem kho rau ntau yam kev tsim kho cov ntawv thov los ntawm kev sib txawv ntxiv. Nov yog 10 hom qhob hauv cov kev tsim kho, nrog rau cov pom zoo ntxiv rau txhua hom:

1. Lub Zog Zog Ntawm Lub Zog:
   • Ntxiv: Dej-txo cov neeg sawv cev (superplasticizers), siv lub sijhawm khov kho), kom ncua sij hawm lub sijhawm), kom ncua sijhawm (kom nrawm dua thaum lub sijhawm huab cua txias).
2. High-zog Qhob:
   • Ntxiv: Cov dej ntws loj-txo cov dej num (superplasticizers), txhawm rau txhim kho lub zog (los txhim kho (los pab txhawb kom muaj zog thaum ntxov).
3. Hnav qhob:
   • Ntxiv: Lub Hnav Hlau Ntsig (xws li nthuav dav av, shale, lossis cov neeg sawv cev ua haujlwm (txhawm rau tsim cov neeg sawv cev (los tsim cov khoom siv ntawm tes lossis ua npuas ncauj).
4. Hnyav hnyav qhob:
   • Ntxiv: Kev sib xyaw ua ke hnyav (xws li narite, magnetite, lossis txo cov ore), txhawm rau txhim kho cov ntsiab lus dej thiab nce lub zog).
5. Fiber ntau-assefauled qhob pob zeb:
   • Ntxiv: Steel fibers, hluavtaws fibers (xws li polypropylene lossis nylon), los txhim kho tensile lub zog, tawg kuj, thiab tawv).
6. Kev sib xyaw ua ke ua vaj tse (SCC):
   • Ntxiv: Cov dej ntws ntau-txo cov neeg sawv cev (tswj hwm superplicify), los tswj kev hloov pauv (los tswj kev ruaj khov thaum lub sijhawm thauj mus los thiab tso).
7. Pervious Qhob:
   • Ntxiv: coarse aggregates nrog qhib voids, dej-txo cov dej num (kom txo cov ntsiab lus dej tsis muaj kev cuam tshuam ua haujlwm), thiab cov fibers (txhawm rau txhim kho cov qauv kev cai lij choj).
8. SHOTETRETE (TXAU QHOB):
   • Ntxiv: Accelerators (txhawm rau txhawm rau ua kom lub sijhawm thiab txo qis), txhawm rau txhim kho cov neeg sawv cev (txhawm rau kom muaj zog (txhawm rau kom muaj pa), thiab txo cov kab mob sib cais).
9. Xim Qhob:
   • Ntxiv: Cov xim sib xyaw ua ke (xws li hlau oxide pigments lossis cov khoom siv hluavtaws (stains)
10. Kev ua haujlwm siab ua haujlwm (HPC):
    • Ntxiv: Silica fume (txhawm rau txhim kho lub zog, ua kom muaj zog ntxiv, kom txo cov ntsiab lus dej thiab ua kom muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv corrosion).

Thaum xaiv cov khoom sib ntxiv rau cov pob zeb ua, nws yog qhov tseem ceeb kom xav txog yam ntxwv xws li cov kev xav tau, ib puag ncig cov kev xav tau, thiab sib xyaw nrog lwm cov ntaub ntawv hauv kev sib xyaw. Ib qho ntxiv, sab laj nrog cov vaj tse ua vaj tse, engineers, lossis cov kws tshaj lij ua kom ntseeg tau tias xaiv tau zoo thiab muab tshuaj ntxiv rau koj daim ntawv thov tshwj xeeb.
