Tam sim no, cov pob zeb hauv av tau ua ib qho tseem ceeb ntawm cov pob zeb tshiab, Pob zeb Travertine Pob zeb nws tau pom zoo tias feem ntau siv cov pob zeb me me (slag, fly ash, silica fume, etc.) siv hauv cov pob zeb ua tau los ua ib qho kev ua tau zoo. Lub koom haum ntawm cov hmoov tshauv, hmoov av hmoov av thiab lwm cov pob zeb hauv av tau zoo tuaj yeem txhim kho kom haum ntawm cov pob zeb ua haujlwm. Txoj kev loj hlob ntawm kev ua vaj tse, cov ntoo tshauv thiab cov slag thiab lwm yam siv los ntawm kev siv loj-loj, Travertine Pob zeb uas ua rau lub khw muag khoom ntoo tshauv, ntxhia hmoov thiab lwm cov nqi hluav taws xob nce nqi, cov khoom nce ntxiv. Qhov ua kom tsis muaj teeb meem ntawm cov pob zeb hauv av tsis txaus ntseeg, kev siv cov limestone hmoov los ua cov pob zeb ua ke, muaj cov ntsiab lus nram no: ib qho kev daws teeb meem ntawm cov kev siv tsis tshua siv nyob rau hauv Suav teb, qhov kev tsis sib haum xeeb thiab kev thov kom yooj yim. Chongqing hauv zos thaj chaw debestone hauv kev pab cuam, Travertine Pob zeb zoo thiab pheej yig, uas yuav tsim kho qhov tsis muaj teeb meem ntawm kev teeb meem kev qis. Tab sis kuj tuaj yeem lav tau qhov kev tsim kho lub zog ntawm thaj chaw ib puag ncig, ua kom siv cov kev pab hauv zos los txhawb lub Tuam Tshoj lub tuam tsev cov ntaub ntawv ua lag luam.
Nrog rau kev nce hauv limestone hmoov cov ntsiab lus, pob zeb tawg thiab 1 k slump nyob rau hauv Table 2. Nws tuaj yeem pom los ntawm Table 2 uas raws li cov limestone hmoov ntsiab los ntawm 0 kg / m3 mus txog 90 kg / m3, thawj lub pob ntawm cov pob zeb tau khaws cia ntawm 210 mm thiab 250 hli, thiab lub slump nce ntawm 170 mm mus rau 240 mm. Nrog rau cov ntsiab lus ntawm limestone hmoov, qhov kev poob qis poob ntawm 40 hli hauv pawg 1 mus rau 10 hli hauv pab pawg 5, Travertine Pob zeb thiab nce ntawm cov hmoov limestone cov ntsiab lus tau txo qhov qeeb ntawm pob zeb. Ntawm lawv, limestone hmoov cov ntsiab lus yog siab tshaj 50% ntawm cov pob zeb hauv av admixtures, 1h slump poob qis heev.
Nrog cov pob txha limestone nce, Travertine Pob zeb qeeb ntawm cov cag slag ua loj dua thiab qhov poob qis qis qis, uas yog vim yog cov nyom morphological thiab kev ntxim ntawm cov hmoov limestone. Qhov ntom ntawm cov xim thiab tus limestone cov hmoov lim xyaw dispersed hauv cov cement particles, ua si lub luag hauj lwm hauv cov dispersant, tuaj yeem txhawb cov av thaum ntxov ntawm cov tshuaj, qhov kev txhim kho cov kev kawm ntawm cov pob zeb. Lub limestone hmoov yog finer thiab muaj ib thaj chaw tsis tshua muaj deg, Travertine Pob zeb yog li ua qhov flowability ntawm cov dej. Vim limestone hmoov yog me dua li qhov xis ntawm xis mas, nws muaj peev xwm ua kom sib txawv ntawm xis mas thiab ya tshauv thiab ua si lub luag hauj lwm ntawm txhaws pob txha, yog li ua kom kev ua tiav ntawm cov pob zeb.
