Peb lub teb chaws yog "cov neeg siv khoom loj" ntawm iav.Nrog rau txoj kev loj hlob sai ntawm kev lag luam, iav noj tau nce zuj zus ib hnub dhau ib hnub, thiab cov iav pov tseg tau maj mam dhau los ua qhov teeb meem thorny.Lub ntsiab tivthaiv ntawm iav yog active silica, yog li tom qab tau hauv av rau hauv hmoov, nws muaj peev xwm muaj pozzolanic kev ua si thiab yuav siv tau raws li ib tug admixture los npaj pob zeb.Qhov no tuaj yeem tsis tsuas yog daws qhov teeb meem ntawm kev pov tseg cov iav pov tseg, tab sis kuj txhawb kev tsim cov khoom siv hauv tsev ntsuab thiab ib puag ncig zoo.HCM Machineryyog ib qho kev sib tsoo zeb chaw tsim tshuaj paus.Kev sib tsoo zeb peb tsim yog cov cuab yeej siv los zom cov iav khib nyiab.Hnub no kuv yuav qhia koj txog lub luag haujlwm ntawm iav hmoov ntawm cov cement.

Los ntawm kev txheeb xyuas qhov kev ntsuas lub zog ntawm cov pob zeb sib xyaw nrog cov iav hmoov thiab cov txiaj ntsig ntawm kev tshuaj ntsuam xyuas ntawm cov cement paste, nws tuaj yeem txiav txim siab tias txawm tias CaO ntawm iav hmoov tuaj yeem hnov ​​​​mob nrog dej, nws tsis muaj zog heev.Yog li, nws tuaj yeem suav hais tias iav hmoov tsis muaj hydraulic hardness.Thaum cov iav hmoov sib xyaw yog 10%, piv txwv li, cov active silica, alumina thiab calcium hydroxide nyob rau hauv cov iav hmoov reacts los tsim tsawg-alkalinity hydrated calcium silicate.Lub active silica kuj tuaj yeem hnov ​​​​mob nrog high-alkalinity hydrated calcium silicate.Calcium silicate hydrate reacts los tsim low-alkali calcium silicate hydrate.Thaum txo cov calcium hydroxide cov ntsiab lus, ib feem ntawm hydrated calcium silicate yog generated, uas txhim kho qhov ceev thiab impermeability ntawm hardened slurry;Nws reacts nrog cov cement hydration khoom calcium hydroxide (Ca(OH)2) los tsim cov dej Hydrated calcium silicate txo cov ntsiab lus ntawm Ca(OH)2 hauv pob zeb, nce cov ntsiab lus ntawm hydrated calcium silicate, thiab txhim kho lub zog ntawm pob zeb. Cov iav hmoov cov ntsiab lus nce mus txog 20%, vim tias cov cement cov ntsiab lus txo qis, cov hydrates generated los ntawm cov cement hydration kuj txo, tab sis cov iav hmoov reacts nrog cement hydrates los ua ib feem hydrated calcium silicate.Thaum cov iav hmoov nce mus txog 20%, lub zog. yog tseem muab piv rau benchmark qhob.Thaum cov iav hmoov txuas ntxiv nce ntxiv thiab cov cement cov ntsiab lus maj mam txo, cov khoom hydration yuav tsawg thiab tsawg, thiab cov iav hmoov reacts nrog cement hydrates Qhov nce hydrate tsis txaus los them rau qhov txo qis hauv hydration khoom los ntawm txo cov ntsiab lus ntawm cov cement.Yog li ntawd, lub zog tau qis dua thiab qis dua.Nws tseem pom tau tias thaum cov iav hmoov ntau dhau lawm, cov kab nrib pleb yuav tshwm sim.

Qhov no yog vim hais tias thaum tus nqi ntawm cov cement txo, qhov kev thov rau silica nquag koom nrog cov tshuaj tiv thaiv hydration kuj txo.Qhov seem active silica reacts nrog alkaline tshuaj nyob rau hauv iav hmoov, ua rau sab hauv expansion ntawm cov pob zeb.Lub hardened cement paste tseem yuav tawg thiab tsim cov kab nrib pleb loj, thiab lub zog ntawm cov pob zeb yuav raug txo.

Cov nyhuv ntawm iav hmoov rau cement:

(1) Lub 28-hnub compressive lub zog ntawm cov pob zeb npaj nrog cov xim tsis muaj pob tshab iav hmoov thiab cov iav ntsuab hmoov sib xyaw nrog 10% thiab 15% ntawm cov cement es tsis txhob cov cement yog siab dua li cov qauv ntawm cov pob zeb;thaum qhov ntau npaum li cas yog 20%, lub zog yog tib yam li cov qauv ntawm cov pob zeb.Piv rau pob zeb;Thaum cov koob tshuaj yog 30% thiab siab dua, lub zog compressive ntawm pob zeb txo qis ntau.

(2) Thaum tsis muaj iav hmoov ntxiv, calcium hydroxide crystallizes zoo thiab loj dua.Raws li tus nqi ntawm cov iav hmoov nce, cov ntsiab lus ntawm calcium hydroxide maj mam txo qis thiab crystallization zuj zus tuaj.

(3) Ntxiv iav hmoov ntawm cov xim sib txawv tsis muaj kev cuam tshuam zoo rau lub zog ntawm cov pob zeb.

(4) Cov hmoov iav yog siv los npaj cov pob zeb thiab muaj cov txiaj ntsig zoo ntawm ecological.

The role and economic benefits of glass powder on cement: Glass powder replaces cement, which can save 19,300 kW. , NOx15.1 t. If 20% of the 3.2 million tons of waste glass produced every year in our country is used to prepare concrete, there will be great ecological and economic benefits. The waste glass grinding machine produced by HCM Machinery is equipment for producing glass powder. It can process 80-600 waste glass powder to meet the processing needs of glass powder cement substrate. If you have relevant needs, please give us a call for details：hcmkt@hcmilling.com
