Izakhiwo Technical Izingxube ukhonkolo

Ngo ukusebenza imikhiqizo ephuma ngokhonkolo njalo nakakhulu noma zisitshekelwe amanzi izakhiwo Monolithic, mhlawumbe ebaluleke kakhulu workability ukhonkolo ibizwa ngokuthi noma kanjani ngokuthi udoboformuemost - ikhono ngokhonkolo ukugcwalisa uphawu yokugcwalisa ifomu olukhethiwe kodwa balondoloze homogeneity yayo. Uma kokuhlaziywa lokhu impahla isetshenziswa izici ezilandelayo:
• Mobility ingxube - kwesakhiwo amandla izici;
• Ukuqina - nobuntu viscosity othakazelisayo ingxube;
• Ukuxhumana - kubonisa ikhono ingxube phakathi kwamanzi emzimbeni sokulungisa.
Mobility we okuholela "Liquid Stone" kuthiwa latholakala ngokulinganisa indawo ukuwa kwayo, wenza ingxube test. I kwenze lichazwa ngokuthi isilinganiso amagugu ezimbili yokukala Izigaxa eyenziwe isampuli eyodwa kwengoma. Esimweni lapho zero ukuwa, workability ingxube libhekene rigidity layo.
I ukuqina we ukhonkolo, kodwa kunalokho ingxube yawo kunqunywa vibration, edingekayo ukuze wenze kube bushelelezi futhi uphawu pre-cast Isigaxa ukhonkolo licwile idivayisi sokunquma ukuqina. Idivayisi ine kwangaphakathi cylindrical indandatho 240 mm ububanzi kanye 200 mm ukuphakama. Kulesi indandatho ibekwe Isigaxa ejwayelekile futhi usigcwalisa ingxube tapho Isigaxa iyasuswa. Wensimbi disc usebenzisa tripod sehliselwe ku- kobuso Isigaxa kwakhiwa kusukela ingxube test. Ngemva kwalokho, ngesikhathi esifanayo ukuqala isitophuwashi kanye vibroplatform. Vibroplatform usebenza nje ukwabiwa kungaqali ingxube usimende ngokusebenzisa ezinhlanu milimitha orifice disc. Kuleli qophelo kube kwenziwa zokuthola isikhathi. Lesi isikhathi vibration compaction, futhi kuwuphawu ubulukhuni ukhonkolo. Khiqiza izilinganiso ezimbili ukwakheka efanayo, futhi isikhathi sokuphela lichazwa ngokuthi isilinganiso amanani amabili kulinganiswa.
isakhiwo Njengomsindo uxhumano ephawula homogeneity we mix ukhonkolo kanye jikelele izakhiwo ukhonkolo. Igcina homogeneity we mix ukhonkolo phakathi zokuthutha, ku yokugcwalisa ifomu bese uphawu - umsebenzi obaluleke kakhulu futhi kunzima. Ngo inqubo uphawu hlamvu Kuhlangana akha ingxube nokuhlukaniswa kwemihlambi okukhishwa kukho amanzi ukuthi bephushelwa phezulu.
Enye indlela enkulu ukuba ulwe besigaxa umkhiqizo ukhonkolo ukunciphisa umthamo wamanzi ekulungiseleleni ukwakheka kokuqala ukhonkolo, isicelo izingxenye ezehlukahlukene plasticizing, futhi egcina amanzi ngcono esebenzisa nenye ezikhethwe ngokucophelela eluhlaza izingxenye wokudla.
