Txhim kho Mortar Performance nrog Cenospheres

Nyob rau hauv xyoo tas los no, kev siv cov cenospheres hauv mortar ntau lawm tau txais kev saib xyuas zoo vim lawv lub peev xwm los txhim kho ntau yam khoom ntawm mortar. Ntau cov kev tshawb fawb tau ua los ntsuas qhov cuam tshuam ntawm cenosphere suav nrog rau cov kev ua haujlwm tseem ceeb xws li kev ua haujlwm, qhov ntom ntom, nqus dej, compressive zog, flexural zog, hluav taws kub tsis kam, acid tsis kam, thiab ziab shrinkage. Tsab ntawv xov xwm no yog lub hom phiaj los muab cov lus qhia dav dav ntawm cov kev tshawb fawb no thiab qhia txog qhov kev pom zoo ntau npaum li cas ntawm cenospheres hauv mortar formulation.

Workability thiab ntom:Cenospheres , lub teeb yuag hollow ceramic microspheres, tau pom los cuam tshuam kev ua haujlwm ntawm mortar zoo. Cov duab kheej kheej thiab kev faib tawm ntawm cov cenospheres pab txhawb kev ntim khoom zoo dua qub, ua rau muaj kev ua kom zoo dua qub thiab txo cov dej xav tau thaum sib tov. Tsis tas li ntawd, kev sib koom ua ke ntawm cenospheres ua rau txo qis hauv mortar ntom, ua rau nws hnyav dua thiab yooj yim rau kev ua haujlwm thaum lub sijhawm tsim kho.

Kev nqus dej thiab compressive zog : Kev tshawb fawb tsis tu ncua qhia tau hais tias kev suav nrog cenospheres nyob rau hauv mortar formulations ua rau txo cov dej nqus. Lub kaw-cell qauv ntawm cenospheres ua raws li ib tug barrier rau dej ingress, yog li txhim kho lub durability thiab noo noo tsis kam ntawm mortar. Lub xub ntiag ntawm cenospheres txhim khu kev sib txuas ntawm kev sib txuas ntawm cov cementitious matrix thiab aggregates, ua rau kom muaj zog compressive ntau dua piv rau cov khoom sib xyaw ua ke.

Flexural Strength thiab hluav taws kub tsis kam: Ib qho tseem ceeb ntawm kev sib koom ua kecenospheres nyob rau hauv mortar yog kev txhim kho ntawm flexural zog. Tsis tas li ntawd, cenospheres pab txhawb kev txhim kho hluav taws kub ntawm mortar los ntawm kev ua raws li hluav taws kub retardants. Lub inert xwm thiab siab melting point ntawm cenospheres inhibit nplaim propagation thiab txo cov kev pheej hmoo ntawm kev puas tsuaj nyob rau hauv cov hluav taws-exposed puag ncig.

Acid Resistance thiab Drying Shrinkage : Cenosphere-reinforced mortars qhia txog kev txhim kho cov kua qaub tiv thaiv los ntawm cov tshuaj inertness ntawm cenospheres. Mortar specimens uas muaj cenospheres tuaj yeem txo qis kev raug mob rau cov kua qaub, ua rau lub neej ntev ntawm cov qauv hauv qhov chaw corrosive. Tsis tas li ntawd, kev koom ua ke ntawm cenospheres txo qhov ziab kom qhuav hauv mortar, ua rau txhim kho qhov ruaj khov thiab txo kev pheej hmoo ntawm kev tawg.

Hauv kev xaus, qhov suav nrogcenospheres nyob rau hauv mortar formulations muaj ntau yam kev pab cuam nyob rau hauv ntau yam kev ua tau zoo tsis. Cov kev tshawb fawb tau pom tiasmortar sib tov uas muaj 10-15% cenospheres ua tiav qhov zoo tshaj plaws Nyob rau hauv cov nqe lus ntawm kev ua hauj lwm, ceev, dej nqus, compressive zog, flexural zog, hluav taws kub tsis kam, acid kuj, thiab qhuav shrinkage. Los ntawm kev siv cov khoom tshwj xeeb ntawm cenospheres, cov neeg tsim khoom mortar tuaj yeem tsim cov ntaub ntawv ua tau zoo uas ua tau raws li qhov xav tau ntawm kev tsim kho kev lag luam. Qhov kev paub sib koom no ua rau txoj hauv kev rau kev tsim kho tshiab thiab kev ruaj ntseg hauv kev tsim cov tshuaj khib nyiab.
