Dab tsi yog qhov yuav tsum tau xav txog hauv kev xaiv cov khoom sib xyaw siv rau lub tsev mortar?

Kev xaiv ntawm cov khoom sib xyaw rau lub tsev mortar yog qhov tseem ceeb vim nws ncaj qha cuam tshuam rau cov khoom thiab kev ua haujlwm ntawm cov mortar. Ntau yam yuav tsum tau xav txog thaum xaiv cov khoom sib sau:

1. Particle Loj Distribution: Aggregates yuav tsum muaj qhov zoo-qib particle loj faib kom ntseeg tau tias ntim khoom thiab txo cov voids hauv cov khoom sib tov. Kev sib npaug sib npaug ntawm cov ntxhib, nplua, thiab muab tub lim pab txhim kho kev ua haujlwm thiab lub zog.
2. Particle Shape: Cov duab ntawm aggregates cuam tshuam rau kev ua haujlwm, cohesiveness, thiab lub zog ntawm mortar. Angular los yog ntxhib-surfaced aggregates muab cov neeg kho tshuab kev sib tshuam zoo dua thiab txhim kho daim ntawv cog lus lub zog piv rau cov sib npaug los yog du-surfaced aggregates.
3. Deg Kev ntxhib los mos: Qhov kev ntxhib los mos ntawm aggregates cuam tshuam kev sib raug zoo ntawm cov khoom sib sau thiab cov tshuaj khib nyiab. Aggregates nrog cov ntxhib ntxhib ntxhib ntxhib ntxhib ntxhib zoo muab kev sib zog ua kom muaj zog thiab adhesion piv rau cov khoom sib xyaw ua ke.
4. Absorption thiab Moisture Content: Aggregates yuav tsum muaj qhov nqus tsawg los tiv thaiv kev nqus dej ntau dhau los ntawm cov tshuaj khib nyiab, uas tuaj yeem ua rau txo qis kev ua haujlwm thiab lub zog. Cov dej noo ntau dhau hauv cov khoom sib xyaw kuj tuaj yeem ua rau lub ntim hloov pauv thiab cuam tshuam rau kev ua haujlwm ntawm cov mortar.
5. Particle Density thiab Specific Gravity: Aggregates nrog ntau dua particle ntom thiab lub ntiajteb txawj nqus tshwj xeeb pab txhawb rau denser thiab muaj zog mortar sib tov. Lub teeb yuag aggregates tuaj yeem siv los txo qhov hnyav ntawm mortar thiab txhim kho thermal rwb thaiv tsev.
6. Kev huv huv thiab huv: Cov khoom sib xyaw yuav tsum tsis pub dawb los ntawm cov khoom siv organic, av nplaum, silt, plua plav, thiab lwm yam kab mob uas tuaj yeem cuam tshuam rau cov khoom ntawm cov mortar. Cov kab mob sib kis tuaj yeem ua rau tsis zoo ntawm daim ntawv cog lus, teeb meem ua haujlwm ntev, thiab staining nto.
7. Durability: Lub durability ntawm aggregates yog qhov tseem ceeb los xyuas kom meej qhov kev ua haujlwm ntev ntawm cov tshuaj khib nyiab. Aggregates yuav tsum tiv taus huab cua, tshuaj tua kab mob, thiab khov-thaw cycles kom muaj kev ncaj ncees ntawm mortar thaum lub sij hawm.
8. Muaj thiab Nqi: Xav txog qhov muaj thiab tus nqi ntawm cov khoom sib sau ua ke, tshwj xeeb tshaj yog rau cov kev tsim kho loj. Cov khoom sib xyaw hauv zos feem ntau nyiam kom txo cov nqi tsheb thauj mus los thiab kev cuam tshuam ib puag ncig.

Los ntawm kev txiav txim siab txog cov xwm txheej no, cov neeg tsim khoom thiab cov kws tsim qauv tuaj yeem xaiv cov khoom sib xyaw tsim nyog uas ua tau raws li cov kev xav tau tshwj xeeb thiab cov qauv kev ua tau zoo rau kev siv lub tsev mortar.
