Qhuav mix mortars yog siv dav hauv kev tsim kho kev lag luam vim lawv qhov zoo ntawm kev tsim kho sai, kev ua haujlwm siab thiab tus nqi qis. Txawm li cas los xij, kev ua tau zoo ntawm cov khoom sib tov qhuav yog nyob ntawm qhov kev xaiv ntawm cov khoom siv raw thiab cov txheej txheem tsim khoom. Los ntawm kev ntxiv cov khoom siv ntxiv polycarboxylate superplasticizer, kev ua haujlwm ntawm cov khoom sib xyaw qhuav tuaj yeem txhim kho tau zoo, ua rau lawv yooj yim rau kev sib tov, thauj thiab siv.
Vim lawv lub peev xwm muaj zog rau dispersing cement particles thiab lawv cov dej txo cov nyhuv, cov pob zeb additives polycarboxylate superplasticizer tuaj yeem ua kom lub zog ntawm cov khoom sib tov qhuav thiab txo lawv cov shrinkage thiab tawg. Nyob rau tib lub sijhawm, pob zeb additives polycarboxylate superplasticizer kuj tau hloov kho rau cov qauv sib txawv thiab tuaj yeem siv nrog ntau yam ntawm cov ntaub ntawv raw, ua rau lawv haum rau ntau hom kev siv tshuaj khib nyiab qhuav.
