Iyi nzira inoshanda mukutsunga kwemotokari yehunyoro hweshiri yechidhori portland portland, yakajairika portland simende, slag portland simende uye mamwe marudzi ezvemiti akasarudzwa kuti ashandise nzira iyi.
2. Zvinyorwa
GB177 SEMEN DEMENT Simba Esigiro Test nzira
GB178 SART SAD YENYAYA YENYAYA TENGE
JBW 01-1-1 Standard Sampuli yeFluidity yeSumbam Motar
3. Iyo nzira yekuona yekudzora kwemvura mwero we moter ndeye inotevera:
3.1 zviridzwa nemidziyo
A. MOTH MOMEER;
B. Svetuka tafura (5mm tsick girazi racho rinofanira kuwedzerwa);
C. Cylindrical Ramming Bar: Yakagadzirwa neSimbi Zvinyorwa, Dhiamita 20mm, kureba anenge 185mm;
D.
E. Mutongi (kuyera huwandu 300mm) kana calipers nekuyera huwandu 300mm;
F. Spatula.
G. Balance yezvinodhaka (inorema 1000G, kunzwa 1G).
3.2. Kuongorora maitiro
3.2.1 Kuyera iyo mvura yekudhirowa yemutengesi
A. WEGE 300G SEENT uye 750G yakajairwa jecha uye udururire muhari yekusanganisa, tanga iyo musanganiswa, wedzera mvura zvishoma nezvishoma mushure mekusanganisa 5s, wozovaburitsa mukati memakumi matatu. Rega kumirira 3min mushure mekutanga muchina. Svina durari kubva pamabhuruku uye bvisa pani inosimbisa.
B. Mukuvhenganiswa nemunguva imwe chete, nejira rejasi rekupukuta tafura tafura, gumburai rakatenderera madziro emukati uye kuiswa pakati pegirazi remukati, rakafukidzwa nejira rakanyorova.
C. Iyo yakavhenganiswa iri yakakamurwa kuita zvikamu zviviri mumuviri, denderedzwa rekutanga kuiswa kubva kumucheto kusvika pamatenderekedzo miviri yakakwira kupfuura mhou dzakatenderedza, iro dhizaini imwe chete yezasi, iyo tsvimbo imwecheteyo inodzamisa gumi neshanu. Kana gadzira jecha uye ramming, tinya iyo truncate Cone inofa neruoko kuti udzivise kufamba.
D. Pashure pekutambidza, bvisa chiumbwa cheMold, shandisa spatula yekubvisa dhiraivha iyo yakakwira kupfuura iyo concar Shake maoko necrank yevhiri kuti iite tafura yekusvetuka ichisvetuka makumi matatu pachiyero cheimwe chechipiri.
E. Pashure pekurova, shandisa calipers kuyera diamita yedhara pasi, uye utore kukosha kwepakati peyamwari miviri perpendicular kune mumwe nemumwe seyakaoma kana mvura ichishandiswa, inoratidzwa muMM. Kana defar referenti yakaenzana ne140 × 5mm, mvura yekunwa mvura ndiyo mvura yekudhara yemuterevhizheni.
3.2.2 Maererano 3.2.1 Maitiro emvura, iyo mvura yekudhara yemutya ane mumiririri-kuderedza kwemvura kusvika pa140 5mm.
3.3. Iyo yekudzora mvura chiyero cheBord Mortar inoverengwa seinotevera:
Kuderedza kwemvura kwemugwagwa (%) = (W0-w1) / w0 × 100
Kupi, w0 - mvura yekudhara (g) kana iyo iyo yakashata yeRealer Dope ndeye 140 × 5mm;
W1 - mvura yekudhara (g) kana iyo yakasarudzika yemutema ine mumvura-kuderedza mumiririri ane zana nemakumi mairi neshanu 5mm.
Iko kukosha kwemvura kuderedzwa kwemvura ndiyo iyo arithmetic zvinoreva kukosha kwematatu samples.
