Ob-txheej txheej txheej txheem tseem ceeb, muab faib ua 5 txheej, los ntawm cov khoom siv rau saum, cov khoom siv, ua ke, cov khoom siv cement. Txoj kev twg yog qhov haum yog nyob ntawm txoj kev xwm txheej.
Lub luag haujlwm ntawm Jingbiao Lub Tsev Haujlwm Jingbiao yog qhov tseem ceeb rau hauv cov hauv qab no. Ua ntej, nws tuaj yeem txhim kho cov dej tsis muaj dej thiab tawg-resistant kev ua haujlwm ntawm txoj kev nto. Los ntawm nteg down binders thiab aggregates, xaus tau tuaj yeem ua rau txoj kev sib tw saum npoo av thiab txo qhov kev pheej hmoo ntawm kev pheej hmoo ntawm kev sib tsoo. Qhov thib ob, kev kho kom zoo zoo tuaj yeem txhim kho kev ua yeeb yam ntawm txoj kev saum npoo av. Vim kev xaiv ntawm aggregates thiab kev ua kom zoo dua ntawm cov txheej txheem paving, cov kev taug ua kom zoo nto tuaj yeem muab kev sib txhuam zoo dua thiab txo cov kev pheej hmoo.
