ob hom kev sib xyaw yog dab tsi?
Lawv yog: Hom A : Dej-txo admixtures. Hom B: Retarding admixtures. Hom C: Accelerating admixtures.
Dab tsi yog additives hauv pob zeb?
pob zeb additives yog ntxiv rau qhov sib xyaw ntawm cov dej cement thiab sib sauhauv qhov me me txhawm rau ua kom cov pob zeb ua kom muaj zog, txhim kho kev coj tus cwj pwm thiab tswj kev teeb tsa lossis tawv. Lawv tuaj yeem ua kua lossis hmoov additives.
Dab tsi yog cov khoom ntxiv hauv kev tsim kho?
(hauv cov khoom siv), natural lossis hluavtaws cov ntaub ntawv uas sib xyaw rau hauv cov neeg ua haujlwm khi, pob zeb, thiab mortars los faib cov khoom tsim nyog rau cov khoom tiav thiab txo nws cov nqi Additives tau muab faib ua ntau pawg nyob ntawm lawv lub hom phiaj thiab tus yam ntxwv.
Dab tsi yog cov piv txwv admixtures?
Muaj ob hom kev sib xyaw, viz., tshuaj lom neeg thiab cov ntxhia ntxhia. Accelerators, Retarders, Dej-txo cov neeg ua hauj lwm, Super plasticizers, Cua entraining agents thiab lwm yam. yog cov feem ntau siv tshuaj admixtures. Fly-ash Blast-kuav slag, Silica fume thiab Rice husk Ash yog cov piv txwv ntawm cov ntxhia pob zeb.
