Sensitivity ntawmPolycarboxylate superplasticizer rau qhuav mix mortarrau kev siv dej thiab kev siv dej
Txij li thaum polycarboxylate superplasticizers rhiab heev rau cov kev hloov pauv hauv cov ntaub ntawv raw, ua ke nrog cov yam ntxwv xws li cov dej txo qis, qis cementitious cov khoom sib xyaw thiab kev siv dej tsawg, kev ua haujlwm ntawm cov dej-txo cov neeg ua haujlwm tseem ceeb heev rau cov dej saturation ntawm pob zeb. Yog tias cov pob zeb ntau dhau lawm, yuav muaj qhov tshwm sim tsis zoo xws li kev sib cais ntawm cov pob zeb, qhov dej, slurry khiav, hardening, thiab huab cua ntau dhau. Ntawm qhov tod tes, pob zeb yuav tshwm sim qhuav, ua haujlwm tsis zoo, thiab poob poob loj. Thiab lwm yam teeb meem. Yog li, txhawm rau teb rau qhov teeb meem no, cov lus qhia hauv qab no tau ua:
(1) Cov ntaub ntawv hloov pauv yuav tsum tau siv rau kev sim sib xyaw kom kho qhov sib xyaw kom ua tiav cov txiaj ntsig zoo tshaj plaws;
(2) nyob rau hauv kev siv cov txheej txheem yuav tsum nruj me ntsis tswj tus nqi ntawm Polycarboxylate superplasticizer rau qhuav mix mortar thiab qhob dej noj;
(3) rau cov khoom siv raw hauv kev ntsuas cov dej reducer, sim kho cov dej reducer rau hom "slow", thiaj li ua tiav lub hom phiaj ntawm insensitive rau raw cov ntaub ntawv thiab dej noj.
