Cov nyhuv ntawm Ib qho Tshiab Alkali-dawb Liquid Accelerator Rau Txau Cement Concrete tau tsim

Cov nyhuv ntawm cov kua accelerator tshiab tsis muaj alkali ntawm cov cement pob zeb tau tsim
 

kev piav qhia:

Cement pob zeb yog ib qho ntawm cov khoom siv siv ntau tshaj plaws. Nws yog siv rau hauv ntau yam kev tsim kho xws li txoj kev, vaj tse, txuas hniav, thiab lwm yam. Cov tshuaj tsuag-siv cement pob zeb feem ntau yog siv los ua cov khoom siv hauv ob sab phlu, culverts, thiab lwm yam hauv av. Kev siv cov tshuaj tsuag pob zeb accelerators yog qhov tseem ceeb hauv kev txhim kho cov khoom ntawm cov pob zeb txau. Txawm li cas los xij, kev siv cov tshuaj alkali-based accelerators muaj ntau qhov tsis zoo. Yog li ntawd, yuav tsum muaj lwm yam alkali-free accelerator technology.

Lub Hom Phiaj:

Lub hom phiaj ntawm txoj kev tshawb no yog los tshawb xyuas cov txiaj ntsig ntawm cov kua alkali-dawb accelerator tshiab ntawm cov cement pob zeb.

Cov ntaub ntawv thiab cov txheej txheem:

Tag nrho ntawm peb pawg ntawm cov pob zeb txau tau npaj. Thawj batch yog npaj nrog ib txwm alkali-raws li accelerator, lub thib ob batch yog npaj nrog ib tug alkali-free kua accelerator, thiab lub thib peb batch yog npaj tsis muaj accelerator. Cov khoom ntawm cov pob zeb tshiab thiab tawv tawv tau raug tshuaj xyuas.

Cov txiaj ntsig:

Cov txiaj ntsig tau pom tias qhov sib ntxiv ntawm cov kua alkali-dawb accelerator tshiab ua rau muaj kev nce ntxiv ntawm lub zog thaum ntxov ntawm cov pob zeb txau. Cov pob zeb nrog cov kua alkali-dawb accelerator tshiab muaj lub zog compressive ntau dua li cov pob zeb nrog cov tshuaj alkali-based accelerator ntawm 3, 7, thiab 28 hnub. Lub sijhawm teeb tsa ntawm cov pob zeb nrog cov alkali-dawb accelerator kuj luv dua li ntawm cov pob zeb nrog cov tsoos accelerator. Kev nqus dej thiab porosity ntawm cov pob zeb nrog cov accelerator tshiab tau qis dua cov pob zeb nrog cov tsoos accelerator thiab pab pawg tswj.

Xaus:

Tus tshiab alkali-dawb kua accelerator txhim kho lub zog thaum ntxov, txo lub sij hawm teem, thiab txo cov dej nqus thiab porosity ntawm cov pob zeb txau. Kev siv cov accelerator tshiab no tuaj yeem yog ib qho kev cog lus rau cov tshuaj alkali-based accelerators. Cov kev tshawb fawb ntxiv yog xav tau los tshawb xyuas qhov kev ua haujlwm ntev ntawm cov pob zeb txau siv cov kua alkali-dawb accelerator tshiab.
