Njengento yokuhombisa eyimfuneko ekuhombiseni, i-putty powder sisixhobo esisisiseko sokulinganisa nokulungisa udonga, kwaye sisisiseko esihle sezinye izinto zokuhombisa. Umphezulu wodonga ungagcinwa uthambile kwaye ufana ngokusetyenziswa kwe-putty powder, ukuze iiprojekthi zokuhombisa zexesha elizayo zikwazi ukwenziwa ngcono. I-putty powder ngokubanzi yenziwe ngezinto ezisisiseko, isizalisi, amanzi kunye nezongezo. Zithini imisebenzi ephambili ye-latex powder ephinda inyibilike njengesongezo esiphambili kwi-putty powder:
① Impembelelo kwidaka elisandula ukuxutywa;
A. Ukuphucula ukwakheka kwayo;
B. Ukugcinwa kwamanzi okongezelelweyo ukuphucula ukufuma kwamanzi emzimbeni;
C. Ukwandisa ukusebenza kakuhle;
D. Kuphephe ukuqhekeka kwangethuba.
② Impembelelo kwidaka eliqinileyo:
A. Nciphisa i-modulus ye-elastic ye-mortar kwaye wonyuse ukuhambelana komaleko wesiseko;
B. Yandisa ukuguquguquka kwaye uxhathise ukuqhekeka;
C. Ukuphucula ukumelana nokuphuma komgubo;
D. Ukufunxwa kwamanzi ngamanzi okanye ukunciphisa ukufunxwa kwawo;
E. Yandisa ukunamathela kumaleko osisiseko.
Udaka olungangeni manzi lubhekisa kudaka lwesamente oluneempawu ezilungileyo zokungangeni manzi nokungangeni emva kokuba luqiniswe ngokulungelelanisa umlinganiselo wodaka kunye nokwamkela inkqubo ethile yokwakha. Udaka olungangeni manzi lunokumelana okuhle kwemozulu, ukuqina, ukungangeni manzi, ukuxinana, ukunamathela okuphezulu kunye nefuthe elinamandla lokungangeni manzi kunye nokulwa nokugqwala. Zithini imisebenzi ephambili yaloumgubo welatex ophinda unyibilikenjengesongezo esiphambili kwidaka elingangeni manzi:
① Impembelelo kwidaka elisandula ukuxutywa:
A. Phucula ulwakhiwo
B. Yandisa ukugcinwa kwamanzi kwaye iphucule ukufuma kwesamente;
② Impembelelo kwidaka eliqinileyo:
A. Nciphisa i-modulus ye-elastic ye-mortar kwaye uphucule ukuhambelana komaleko wesiseko;
B. Yandisa ukuguquguquka, imelane nokuqhekeka okanye ube nokukwazi ukubopha;
C. Ukuphucula uxinano lwesamente;
D. Ukungathandi amanzi;
E. Yandisa umanyano.
