1. Ukubukeka:Impushana ensundu ngokukhanyayo&uketshezi olunsundu ngokumnyama.Ayinaphoyizini, ayinaphunga, ayinakushi futhi ayigqwali kuzinti zensimbi.
2. I-Plasticity Ephawulekayo:Njengesimo sokuxutshwa lapho inani likasimende nokugoqeka kulungisiwe ngaphambili, amanzi okuxuba angehla ngo-18-28% uma exutshwe nokhonkolo oqiniswe ngo-0.5-1.0%.Ngokwezibalo, amandla okucindezela ngosuku loku-1, usuku lwe-3 kanye nosuku lwama-28 ngemuva kokufakwa kwesicelo esisodwa akhuphuka ngo-60-90% kanye no-25-60% ngokulandelanayo lapho engezwa ngesilinganiso esijwayelekile se-blend. Njengomphumela, amandla okucindezela, amandla okubamba ,amandla okugoqa kanye nemodulus yokunwebeka kuzothuthukiswa ngezinga elithile.
3. Thuthukisa ukuxubeka kwesihlanganisi sikakhonkolo ngamanzi kanye nokugoqeka futhi.Njengesimo sokuxuba okufanayo, ukugoqa kungandiswa izikhathi ezingu-5-8 uma sengezwe kumthamo wenhlanganisela engu-0.75%.
4. Amaphesenti angu-15-20 kasimende angagodlwa lapho i-ejenti ihlanganiswa kumthamo wenhlanganisela engu-0.75%, okuyisimo sangaphambili sokugoqeka okufanayo namandla.

(IV) UKUSETSHENZISWA:
1.Ukulinganisa umthamo ku-0.5-1%,0.75%ukuxuba umthamo kuyalulekwa.2.Lungiselela izixazululo njenge
okudingekayo.
3. Ukusetshenziswa okuqondile kwe-powder agent kuvunyelwe. Ngakolunye uhlangothi ukwengezwa kwe-ejenti kulandelwa ukuthambisa kwamanzi (isilinganiso samanzi-simende: 60%)
4.I-ejenti ingahlanganiswa namanye ama-ejenti asetshenziswa kakhulu uma ukuthuthukiswa komshayeli noma ukuhlolwa kwelabhorethri kuphumelela.
(V)UKUPAKA, UKUGCINWA KANYE NOKUTHUTHA
1.iphakheji:
Impuphu: ukupakisha esikhwameni sendwangu elukiweyo esinepulasitiki yangaphakathi.Isisindo esiphelele:25kg±0.2kg noma 650kg±0.2kg
2.Izixwayiso:
Kugwenywe ekubeni yi-tom yizinto ezicijile ngenkathi amaphakheji edluliswa noma ehanjiswa.Lapho ingcoliswa umswakama ophezulu noma umswakama uma kwenzeka kuvuza, ingalungiswa ngezindlela ezinqunyiwe ukuze isetshenziswe futhi ngaphandle kokuyeka noma yimuphi umphumela.
3.Kufanele igcinwe endaweni yokugcina impahla enomoya omuhle futhi eyomile. Uma ithinteke ngokuswakama, vele uyiphahlaze noma uyincibilikise ibe yisixazululo ngaphandle kokusebenza kabi.
