Technical ehupfumi nekongiri wemisanganiswa

In chokupika zvigadzirwa kubva Akazadzisa kongiri kana nemafashamo monolithic zvivako, zvichida chinokosha pfuma nekongiri workability zvinonzi kana sei inonzi udoboformuemost - mano kongiri kuti zadza muchimiro ukaguta chisimbiso pamwe nzira akasarudza uye kuramba homogeneity kwayo. Kana kunyatsoongorora pfuma iyi rinoshandiswa zvinotevera unhu:
• mufambo muvhenganiswa - STRUCTURAL simba unhu;
• pokuoma - cho kukumikidza viscosity pakati musanganiswa;
• Connectivity - chinoratidza mano musanganiswa panguva kupera mvura mumuviri nyaya.
Mufambo of zvichizoita "Liquid Stone" dzakatemerwa nokuyera slump kwayo, akaita pamusoro bvunzo nezvakasanganiswa. The precipitate rinorondedzerwa so paavhareji maviri tsika yakayerwa pakati pasikweya akaita chimwe mharidzo sezvamunoita. Kana apo razero slump, workability pamusoro musanganiswa kunoratidzwa kwayo Rigidity.
The kuomarara of kongiri, asi kutoti musanganiswa rayo pakutsvaga vibration, iyo kunodiwa kuitira kuti chechetere uye rakanamwa pre-vakakanda kongiri cône yazara zano kuti kusarudza kuomarara. The mudziyo ane yomukati cylindrical mhete 240 mm mu dhayamita uye 200 mm nekukwirira. In mhete ichi anoiswa mureza cône uye kuzadza nayo musanganiswa dzakatsigira cône chinobviswa. Chiridzwa Disc anokushandisira mutiraipodhi akatura padenga pemvura cône aumba kubva bvunzo musanganiswa. Pashure paizvozvo, panguva iyoyowo kutanga stopwatch uye vibroplatform. Vibroplatform anoshanda sokuvapo yavaive hakurevi kutanga samende musanganiswa kuburikidza shanu millimeter orifice Disc. Panguva ino zviri akaita kugadzira nguva. Iyi ndiyo nguva vibration compaction, uye anozivikanwa nekongiri pokuoma. Zvibereko kuyerwa maviri chete nziyo, uye kuguma nguva rinorondedzerwa so paavhareji maviri akayera tsika.
pfuma yakadaro somunhu kubatana inechirevo homogeneity pamusoro chesamende kunovhengana uye zvinonyatsorehwa zvivako zviri kongiri. Kungoona homogeneity ari chesamende kunovhengana panguva zvokufambisa, ari muchimiro vaguta uye chisimbiso - inokosha zvikuru uye rakaoma. In muitiro rakavhara munhu convergence tsanga vanoumba musanganiswa uye voga ane uwandu remvura iri kusundwa kumusoro.
Imwe nzira huru kurwisa chiputu kongiri chigadzirwa kuti kuderedza uwandu remvura kwegadziriro kutanga Kuronga kongiri, kushanda siyana plasticizing zvinoriumba, uye nani mvura chengetedzo achishandisa musanganiswa munhu kunyatsosarudza bota mbishi zvinoriumba.
