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 nyob ntawm ntau yam, suav nrog:

1. Particle loj faib: Qhov loj me me ntawm cov aggregates cuam tshuam rau kev ua haujlwm, lub zog, thiab porosity ntawm mortar.Kev sib xyaw ua ke nrog ntau qhov ntau thiab tsawg cov qhov ntau thiab tsawg dua thiab txo qhov porosity ntawm cov tshuaj khib, ua rau txhim kho lub zog thiab kav ntev.
2. Puab thiab kev ntxhib los mos: Cov duab thiab kev ntxhib los mos ntawm cov aggregates cuam tshuam rau kev sib txuas ntawm cov tshuaj khib thiab cov substrate.Aggregates nrog angular lossis ntxhib qhov chaw tuaj yeem muab kev sib cuam tshuam zoo dua thiab ua kom zoo dua qub, thaum cov sib xyaw ua ke du lossis sib npaug yuav ua rau muaj kev sib raug zoo dua.
3. Ceev: Qhov ceev ntawm cov aggregates cuam tshuam qhov hnyav thiab ntim ntawm cov mortar.Kev hnyav sib ceg tuaj yeem txo cov txheej txheem hnyav ntawm tus qauv, thaum lub siab ua kom siab muaj peev xwm nce ntxiv lub zog thiab lub zog ua kom huv.
4. Porosity: Lub porosity ntawm cov aggregates cuam tshuam rau cov dej-cement piv thiab ziab shrinkage ntawm mortar.Aggregates nrog porosity tsawg tuaj yeem txo cov dej xav tau thiab ziab kom qhuav, ua rau txhim kho durability thiab txo qhov tawg.
5. Tshuaj muaj pes tsawg leeg: Cov tshuaj muaj pes tsawg leeg ntawm cov khoom sib xyaw tuaj yeem cuam tshuam rau lub sijhawm teem, lub zog, thiab ua haujlwm ntev ntawm cov tshuaj khib.Aggregates nrog qib siab ntawm cov organic teeb meem lossis sulfates tuaj yeem cuam tshuam nrog cov txheej txheem cement hydration thiab ua rau txo lub zog thiab kav ntev.
6. Muaj thiab tus nqi: Qhov muaj thiab tus nqi ntawm cov khoom sib xyaw tuaj yeem sib txawv nyob ntawm qhov chaw thiab qhov xav tau.Kev muaj cov khoom sib xyaw hauv zos tuaj yeem txo cov nqi tsheb thauj mus los thiab kev cuam tshuam ib puag ncig, thaum cov khoom sib xyaw ua ke zoo tuaj yeem ua rau tus nqi ntawm cov mortar.
