1. Kev soj ntsuam ntawm admixture rhiab heev
Ua kom cov pob zeb sib xyaw ua kom sib piv tsis hloov pauv, kho qhov sib npaug ntawm qhov sib tov, coj qhov pib nthuav dav ntawm pob zeb ntawm (400 ± 10) mm ua qhov pib, thiab tom qab ntawd nce qhov nyiaj. Thaum pib nthuav dav ntawm pob zeb yog (550 ± 10) mm, txiav txim siab qhov kawg ntawm qhov admixture.Thaum muaj qhov sib txawv ntawm qhov pib thiab qhov kawg ntawm qhov ntau npaum li cas, qhov ntsuas qhov ntsuas dua rov tuaj yeem nqa tawm.dmixture qhov dav=admixture kawg taw tes / admixture pib qhov pib.Qhov loj dua admixture qhov dav yog, qhov tsis tshua muaj nkag me.
2. Ntsuas qhov kub thiab qhov ua tau zoo tshaj qhov ntsuas
Raws li admixture rhiab heev qhov kev ntsuam xyuas tus qauv, admixture xaus qhov kev txiav txim siab tau txiav txim siab raws li admixture reference.Then ua kom cov pob zeb sib xyaw kom xwm yeem, kho chav sov 0-5 ℃, hauv
3. Kev ntsuas qhov ntsuas qhov ua kom tsis muaj dej txaus siv
Raws li qhov kev ntsuam xyuas qhov sib txawv ntawm cov admixture, admixture benchmark txiav txim siab, thiab qhov pib ntawm admixture yuav tsum tau xaiv los ua qhov kev ntsuas.Kuv kom txaus tus nqi ntawm admixture thiab pob zeb sib xyaw ua ke tsis tu ncua, kho cov kev noj haus dej ntawm cov qhob sib xyaw, nce chav dej. tau noj los ntawm 15kg.Qhov sib txawv tus nqi ntawm pob zeb ua kev nthuav qhia qib hauv qab ob dej noj tau xam. Qhov me dua qhov sib txawv muaj nuj nqis yog, qhov ua kom tsis tshua muaj polycarboxylate superplasticizer yog kev siv dej.
4. Kev soj ntsuam xyuas cov khoom raw
Ua kom tsis txhob hloov cov pob zeb sib tov sib xyaw ua ke, hloov ntawm cov cement, xuab zeb thiab lwm yam, raws li qhov ntau ntawm kev ntsuas qhov kev ntsuas qhov kev ntsuas qhov ntsuas ntawm kev ntsuas, qhov ntsuas tsis tau hloov cov khoom nyoos lossis hloov cov khoom nyoos ntawm qhov txuas ntxiv, = nthuav tawm kev hloov pauv ntawm cov ntaub ntawv raw khoom raws li cov khoom siv tshuaj tiv thaiv kev kawm qib siab tus nqi - tsis yog nthuav dav ntawm kev hloov pauv ntawm cov khoom nyoos, suav qhov kev hloov pauv ntawm cov khoom nyoos ntawm txuas ntxiv thiab tsis hloov cov khoom nyoos ntawm cov qib ncua ntev tus nqi, qhov sib txawv me me, hais tias poly carboxylic acid dej txo tus neeg sawv cev nkag siab rau cov khoom nyoos tsawg dua, kev muab tshuaj admixture point tsim nyog xaiv ncua kev kawm ntawv ntawm (480 + 10) hli ntau npaum li cas ntawm cov ntsiab lus raws li tus qauv ntsuas.
