Peb lub teb chaws yog ib lub teb chaws uas siv iav ntau heev. Nrog rau kev loj hlob ntawm kev lag luam sai, kev siv iav nce ntxiv txhua hnub, thiab kev pov tseg cov iav pov tseg tau maj mam ua teeb meem loj heev. Cov khoom tseem ceeb ntawm iav yog cov silica uas ua haujlwm, yog li tom qab raug zom ua hmoov, nws tuaj yeem muaj cov haujlwm pozzolanic thiab tuaj yeem siv ua cov khoom sib xyaw los npaj cov pob zeb. Qhov no tsis tsuas yog daws tau qhov teeb meem ntawm kev pov tseg cov iav pov tseg, tab sis kuj txhawb kev tsim cov khoom siv hauv tsev ntsuab thiab zoo rau ib puag ncig.Cov Tshuab HCMyog lub chaw tsim khoom sib tsoo. Lub tshuab sib tsoo uas peb tsim yog cov khoom siv siv los sib tsoo cov hmoov iav pov tseg. Hnub no kuv yuav qhia rau koj txog lub luag haujlwm ntawm cov hmoov iav rau ntawm cov cement.

Los ntawm kev tshuaj xyuas qhov kev sim zog ntawm cov pob zeb sib xyaw nrog cov hmoov iav thiab cov txiaj ntsig kev kuaj xyuas microscopic ntawm cov cement paste, nws tuaj yeem xaus lus tias txawm hais tias CaO ntawm cov hmoov iav tuaj yeem ua rau dej tsis zoo, nws tsis muaj zog heev. Yog li ntawd, nws tuaj yeem xav tias cov hmoov iav tsis muaj hydraulic hardness. Thaum qhov sib xyaw ntawm cov hmoov iav yog 10%, piv txwv li, cov silica nquag, alumina thiab calcium hydroxide hauv cov hmoov iav ua rau cov calcium silicate qis-alkalinity. Cov silica nquag kuj tseem tuaj yeem ua rau cov calcium silicate siab-alkalinity. Calcium silicate hydrate ua rau cov calcium silicate qis-alkali. Thaum txo cov calcium hydroxide, ib feem ntawm hydrated calcium silicate raug tsim, uas txhim kho qhov ceev thiab impermeability ntawm cov slurry hardened; nws ua rau cov tshuaj calcium hydroxide (Ca(OH)2) uas yog cov cement hydration product los tsim cov dej. Hydrated calcium silicate txo cov Ca(OH)2 hauv cov cement, ua rau cov calcium silicate ntau ntxiv, thiab ua rau cov cement muaj zog dua. Thaum cov hmoov iav muaj txog 20%, vim tias cov cement txo qis, cov hydrates uas tsim los ntawm cement hydration kuj txo qis, tab sis cov hmoov iav ua rau cov cement hydrates tsim cov calcium silicate uas yog cov hydrated ib feem. Thaum cov hmoov iav muaj txog 20%, lub zog tseem zoo ib yam li cov cement benchmark. Thaum cov hmoov iav tseem nce ntxiv thiab cov cement maj mam txo qis, cov khoom hydration yuav tsawg zuj zus, thiab cov hmoov iav ua rau cov cement hydrates. Cov hydrate uas nce ntxiv tsis txaus los them rau cov khoom hydration uas tshwm sim los ntawm cov cement txo qis. Yog li ntawd, lub zog yuav qis zuj zus. Kuj pom tias thaum cov hmoov iav ntau dhau, cov kab nrib pleb yuav tshwm sim.

Qhov no yog vim tias thaum cov cement txo qis, qhov kev thov rau cov silica nquag uas koom nrog hauv cov tshuaj tiv thaiv hydration kuj txo qis. Cov silica nquag uas tseem tshuav reacts nrog cov tshuaj alkaline hauv cov hmoov iav, ua rau sab hauv ntawm cov pob zeb ua vaj tse nthuav dav. Cov cement nplaum uas tau khov kho kuj yuav tawg thiab tsim cov kab nrib pleb loj dua, thiab lub zog ntawm cov pob zeb ua vaj tse kuj yuav txo qis.

Cov nyhuv ntawm cov hmoov iav rau ntawm cov cement:

(1) Lub zog compressive 28 hnub ntawm cov pob zeb ua los ntawm cov hmoov iav tsis muaj xim thiab cov hmoov iav ntsuab sib xyaw nrog 10% thiab 15% ntawm cov cement es tsis txhob cement siab dua li ntawm cov pob zeb benchmark; thaum cov koob tshuaj yog 20%, lub zog yog tib yam li ntawm cov pob zeb benchmark. Sib piv rau cov pob zeb; thaum cov koob tshuaj yog 30% thiab siab dua, lub zog compressive ntawm cov pob zeb txo qis ntau.

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

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

(4) Cov hmoov iav yog siv los npaj cov pob zeb thiab muaj cov teebmeem zoo rau 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
