Technical Indicators
l.Cov khoom yog muab faib ua hmoov thiab kua.Cov hmoov yog xim av-daj.Cov kua yog xim av-xim av.Cov khoom yog non-toxic, tsw tsw thiab tsis-combustible.Yog tsis muaj corrosion nyhuv ntawm cov hlau tuav.
2. Cov khoom no muaj kev txo cov dej kom pom tseeb thiab cov nyhuv dispersion.Cov dej txo yog nyob nruab nrab ntawm 14 thiab 25% (hloov raws li cov neeg siv yuav tsum tau thiab cov cement adaptability).
3. Ntxiv cov khoom rau cov ntub dej condensate, nyob rau hauv tib lub cement ntau npaum li cas thiab tib yam kev poob qis, nws 1d compressive zog tuaj yeem txhim kho los ntawm 40% mus rau 110%, 3d compressive zog los ntawm 40% ~ 90%, 7d Hangzhou compression zog tuaj yeem yuav tsum tau txhim kho los ntawm 30 ~ 80%, thiab 25% mus rau 50% zoo heev txhim kho lub cev thiab txhua yam kev ua tau zoo ntawm 50% ntawm cov pob zeb.Ua kom lub zog compression thiab folding lub zog ntawm cov pob zeb.Qhov elastic modulus thiab durability yog txhim kho raws li.
4. Txhim kho qhov yooj yim ntawm cov pob zeb sib tov sib xyaw thiab ua kom cov slump.Nyob rau hauv tib cov cement ntau npaum thiab dej rau cov hmoov tshauv piv.Koom nrog cov khoom no.Qhov slump ntawm cov pob zeb yuav ua rau muaj kev nce ntxiv. Txhim kho qhov yooj yim ntawm pob zeb.Qhov kev poob qis tuaj yeem nce ntau dua 12cm.
5. Ua tib yam slump thiab lub zog theem.Koom nrog cov khoom no.Can txuag ntau tshaj 12%.
6. Lub sijhawm condensation thiab khov-thaw qib tuaj yeem hloov kho raws li qhov xav tau tiag tiag ntawm qhov project.
