Pob zeb yog a ceramic composite ua los ntawm dej, xuab zeb, gravel, crushed pob zeb, thiab cement . Cov khoom xyaw yog tov ua ke kom huv si, thiab yog poured rau hauv ib daim ntawv. Tom qab lub pob zeb yog qhuav tag, nws muaj zog compressive zoo heev.
Yog li ntawd, cov cement puas yog ceramic?
Ib txwm ceramics suav nrog cov khoom siv av nplaum, silicate iav thiab cement ; thaum nce qib ceramics muaj carbides (SiC), ntshiab oxides (Al2O3), nitrides (Si3N4), tsis yog-silicate iav thiab ntau lwm yam. Ceramic cov ntaub ntawv nthuav tawm ntau yam khoom siv uas pab txhawb lawv siv hauv ntau qhov chaw sib txawv.
Ib tug kuj yuav nug, yog iav ceramic? iav tuaj yeem hu ua hom ceramic . iav paub tias yog cov khoom siv uas tsis yog crystalline. Nws yog ib qho amorphous khoom, uas txhais tau hais tias nws tsis muaj qhov ntev-ntau qhov kev txiav txim ntawm qhov chaw ntawm nws cov molecules. Tsis zoo li iav , ceramics tej zaum yuav muaj crystalline los yog ib nrab crystalline lug.
Yog li ntawd, hom khoom siv twg yog ceramic?
A cov khoom siv ceramic yog ib qho inorganic, non-metallic, feem ntau crystalline oxide, nitride los yog carbide khoom . Qee cov ntsiab lus, xws li carbon lossis silicon, yuav raug txiav txim siab ceramics . Cov khoom siv ceramic yog nkig, tawv, muaj zog hauv compression, thiab tsis muaj zog hauv shearing thiab nro.
Puas yog cov pobzeb cement kim dua li ceramic?
Sib piv, zoo sib xws hauv nqi , ob leeg ceramic thiab cov nplais cement ua kim dua ib square feet/ib daim ntau cov ncauj lus kom ntxaws lawv ua (piv txwv li, xuas tes pleev xim los yog qauv cov nplais ).

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Puas yog pob zeb av nplaum yog pob zeb sedimentary?
Boulder Clay. Boulder av nplaum los ntawm Yorkshire, UK los ntawm lub sij hawm Pleistocene, qhia random loj ntau yam clasts nyob rau hauv ib tug glacial av nplaum matrix. Tsim los ntawm ntau yam txheej txheem glacial lossis dej khov, cov pob zeb sedimentary no muaj ntau qhov ntau thiab tsawg
Puas yog hlau yog pob zeb lossis pob zeb?
Los yog, cov ntxhia los yog ib qho sib xyaw ntawm cov ntxhia los ntawm cov khoom tseem ceeb, tshwj xeeb tshaj yog cov hlau, tuaj yeem tau txais txiaj ntsig zoo los yog rho tawm yog cov ore. Hlau - Ib qho hlau ntawm ob lossis ntau dua hlau. Yog li ntawd, pob zeb muaj cov zaub mov, uas nyob rau hauv loj concentration yog hu ua ores thiab cov no yog mined rau hlau
