Luso katundu zosakaniza konkire

Mu ntchito za malonda analimbitsa simenti kapena anasefukira nyumba monolithic, mwina chuma chofunika kwambiri workability konkire amatchedwa kapena mmene amatchedwa udoboformuemost - mphamvu konkire lembani mawonekedwe kukhuta chisindikizo ndi njira anasankha akhalebe homogeneity ake. Ngati aziona chuma ichi ntchito makhalidwe zotsatirazi:
• sayenda osakaniza - structural mphamvu makhalidwe;
• Malimbidwe - khalidwe la mamasukidwe akayendedwe wochitachita wa osakaniza;
• zamalumikizidwe - chikusonyeza luso osakaniza pa madzi m'thupi Kuthetsa.
Sayenda ya chifukwa "Phula Stone" atsimikiziridwa ndi kuyeza kuchepa mphamvu zake, zopangidwa ndi osakaniza mayeso. precipitate The amatanthauziridwa kuti avareji mfundo ziwiri muyeso wa cones zopangidwa chitsanzo chimodzi zikuchokera. Ngati kumene ziro kuchepa mphamvu, workability wa osakaniza amakhala ndi chinthu chimodzimodzi ake.
The stiffness wa simenti, koma osakaniza kwake anatsimikiza mtima kugwedera, amene chofunika kuti izo zidzakhala zosalala chidindo chisanadze kuponyedwa konkire phirilo ndakhuta mu chipangizo kwa kudziwa stiffness. chipangizo ali mkati cylindrical mphete 240 mm m'mimba mwake ndi 200 kutalika mm. Mu mphete imeneyi aikidwa mbewa zakufa muyezo, mudzaze ndi osakaniza inatuluka phirilo atachotsedwa. Chida chimbale ntchito miyendo itatu adatchithisira kuyenda pamwamba pa phirilo anapangidwa kuchokera osakaniza mayeso. Pambuyo pake, nthawi yomweyo kuyamba wotchi yoyimitsa ndi vibroplatform. Vibroplatform ntchito malingana ngati Kugawilidwa kwanthaka n'kuyamba osakaniza simenti kupyolera asanu millimeter orifice chimbale. Pa nthawi imeneyi zikhale akukonzekera nthawi. Iyi ndi nthawi ya kugwedera compaction, ndipo khalidwe la kuuma konkire. Ndisonyezeni miyezo iwiri ya kapangidwe yomweyo, ndi nthawi yotsiriza amatanthauziridwa kuti avareji mfundo ziwiri anayeza.
Malo omwe ndi monga kulumikiza amadziwika ndi homogeneity wa konkire Kusakaniza ndi akukhudzidwira katundu wa simenti. Kupulumutsa homogeneity wa konkire Kusakaniza afotokoze mu mawonekedwe kukhuta ndi chisindikizo - ntchito zofunika kwambiri ndi zovuta. Mu ndondomeko ya kusindikiza ndi mgwirizano mbewu amapanga osakaniza ndi kudzipatula ndi kuchuluka kwa madzi kuti akankhidwira m'mwamba.
njira imodzi yaikulu kulimbana mtolo konkire mankhwala ndi kuchepetsa kuchuluka kwa madzi mu yokonza zikuchokera koyamba konkire pempho la zosiyanasiyana zigawo zikuluzikulu plasticizing, ndi bwino madzi posungira mwa osakaniza kusankha mosamala zigawo yaiwisi monga chimanga.
