Hollow concrete thaiv tau los ntawm Cement, aggregate, dej, yuav tsum tau ua nyob rau hauv qhov tsim nyog loj thiab cov duab los ntawm thaiv kev siv lub tshuab , raws li cov pob zeb masonry tsev rau cov khoom siv, qhov loj me yog 4 nti, 6 nti, 8 nti, 10 nti thiab 12-ntim sib txuam sib luag.
Raws li kev siv zog lub zog yog muab faib rau MU3.5, MU5, MU7.5, MU10, MU15, MU20 rau qib kawm.
Cov kev xyuam xim siv:
1. Yog tias cov xuab zeb muaj cure nyob ntawm qhov ntsuas kub ntawm 20 ℃ mus rau 37 ℃ , yuav tsum tau ceev cia rau 28 hnub ua ntej siv.
2.Cov ntub cov ntsiab lus ntawm cov blocks thaum lub sijhawm khoom xa tuaj yuav tsum tau nruj nruj raws li cov txheej txheem
3.Cov dej nag tiv thaiv thaum muab cia rau hauv qhov chaw
Raws li lub zog theem tau muab faib rau cov kabmob ntawm cov kabmob, qhov tsis-load-bearing block, load-bearing block zog yog feem ntau tshaj MU7.5, tsis-ntsaws kabmob nrawm zog theem feem ntau yog hauv qab 5.0
Ordinary qhob hollow thaiv zoo zog:
