10 Hom Qhob hauv Kev Tsim Kho nrog Kev Pom Zoo Ntxiv

Qhob yog ntau yam khoom siv hauv tsev uas tuaj yeem hloov kho rau ntau daim ntawv thov kev tsim kho los ntawm kev sib xyaw cov khoom sib txawv. Ntawm no yog 10 hom kev ua vaj tse feem ntau siv hauv kev tsim kho, nrog rau kev pom zoo ntxiv rau txhua hom:

1. Lub zog zoo li qub:
   • Additives: Dej-txo cov neeg ua hauj lwm (superplasticizers), cua-entraining agents (rau freeze-thaw resistance), retarders (kom ncua sij hawm teem), thiab accelerators (kom ceev lub sij hawm nyob rau hauv huab cua txias).
2. High-Strength Concrete:
   • Additives: Cov dej-txo cov neeg ua haujlwm siab (superplasticizers), silica fume (kom txhim kho lub zog thiab kav ntev), thiab cov accelerators (kom pab txhawb lub zog thaum ntxov).
3. Lub teeb yuag:
   • Additives: Lub teeb yuag aggregates (xws li nthuav av nplaum, shale, los yog cov khoom siv hluavtaws sib sib zog nqus), cov neeg ua haujlwm hauv huab cua (kom txhim kho kev ua haujlwm thiab khov-thaw tsis kam), thiab cov neeg ua npuas dej (los tsim cov cellular lossis aerated qhob).
4. Heavyweight Concrete:
   • Additives: Heavyweight aggregates (xws li barite, magnetite, lossis hlau ore), dej-txo cov neeg ua haujlwm (kom txhim kho kev ua haujlwm), thiab superplasticizers (kom txo cov dej thiab ua kom muaj zog).
5. Fiber-Reinforced Concrete:
   • Additives: Hlau fibers, hluavtaws fibers (xws li polypropylene los yog nylon), los yog iav fibers (los txhim kho tensile zog, tawg kuj, thiab toughness).
6. Self-Consolidating Concrete (SCC):
   • Additives: Cov dej-txo cov neeg ua haujlwm siab (superplasticizers), viscosity-modifying agents (kom tswj tau ntws thiab tiv thaiv kev sib cais), thiab stabilizers (kom muaj kev ruaj ntseg thaum lub sij hawm thauj mus los thiab kev tso kawm).
7. Pervious Concrete:
   • Additives: Coarse aggregates with open voids, water-reduced agents (kom txo cov ntsiab lus dej tsis muaj kev cuam tshuam rau kev ua haujlwm), thiab fibers (los txhim kho cov qauv kev ntseeg siab).
8. Shotcrete (Sprayed Concrete):
   • Additives: Accelerators (kom ua kom lub sijhawm teem sijhawm thiab kev txhim kho lub zog thaum ntxov), fibers (kom txhim kho kev sib koom tes thiab txo qis rov qab), thiab cov neeg ua haujlwm huab cua (kom txhim kho cov twj tso kua mis thiab txo kev sib cais).
9. Xim Xim:
   • Additives: Cov xim tsis muaj xim (xws li hlau oxide pigments lossis hluavtaws dyes), cov xim siv rau saum npoo (stains lossis dyes), thiab cov xim tawv tawv (los txhim kho xim siv thiab ua kom ntev).
10. High-Performance Concrete (HPC):
    • Additives: Silica fume (los txhim kho lub zog, durability, thiab impermeability), superplasticizers (kom txo cov dej thiab ua kom muaj zog), thiab corrosion inhibitors (los tiv thaiv kev tiv thaiv corrosion).

Thaum xaiv cov khoom siv ntxiv rau cov pob zeb, nws yog ib qho tseem ceeb uas yuav tsum xav txog yam xws li cov khoom xav tau, kev ua tau zoo, ib puag ncig, thiab kev sib raug zoo nrog lwm cov ntaub ntawv hauv kev sib xyaw. Tsis tas li ntawd, sab laj nrog cov neeg muab khoom ua vaj tse, engineers, lossis cov kws tshaj lij kom paub meej tias kev xaiv thiab ntau npaum li cas ntawm cov khoom ntxiv rau koj daim ntawv thov tshwj xeeb.
