Qhov ntxiv ntawm calcium formate hauv cement yog dab tsi?

Thaum lub caij ntuj sov, cov tshuaj ntawm Calcium feem ntau yog 0.3% ~ 0.7% ntawm qhov hnyav ntawm cov cement.
Thaum lub caij ntuj no, cov tshuaj yuav tsum nce ntxiv thaum qhov kub poob qis, feem ntau 0.5% ~ 1%, nrog rau qhov siab tshaj plaws ntawm 2.5%.
Rau cov cement (uas feem ntau muaj lub zog thaum ntxov tab sis qis lub zog lig) siv rau hauv cov mortar qhuav, ntxiv cov calcium formate kom tsim nyog rau cov khoom yog qhov zoo rau kev txhim kho lub zog thaum ntxov. Peb cov calcium formate muaj cov kua dej zoo, solubility siab, thiab suav nrog lub luag haujlwm cua-entraining (txuag 1.5% dej thiab txo cov dej ntsiab lus los ntawm 5%). Nws tuaj yeem txhim kho mortar ua haujlwm tau zoo thiab ua kom ruaj khov.

Cov tshuaj calcium formate concrete accelerator muab kev nce zog sai, cov chloride tsawg thiab ua haujlwm tau zoo heev - zoo meej rau kev ua kom zoo dua qub. Nyem kom sab laj nrog peb cov phiaj xwm muab khoom siv tam sim no!
