Udaka olusetyenziswa kakhulu ludaka oluplastayo, udaka olumelana nokuqhekeka kunye nodaka olusebenzisa udongwe. Umahluko wabo ngolu hlobo lulandelayo:
Udaka olumelana nokuqhekeka:
Ludaka olwenziwe nge-arhente yokulwa nokuqhekeka eyenziwe nge-polymer lotion kunye nomxube, isamente kunye nesanti ngomlinganiselo othile, enokufikelela kwinguqu ethile kwaye ingaguquguquki.
I-mortar ekwaziyo ukumelana nokuqhekeka yinto egqityiweyo, enokusetyenziswa ngokongeza amanzi nokuxuba ngokuthe ngqo. Izinto ezigqityiweyo ze-mortar ezichasene nokuqhekeka yintlabathi ecolekileyo, isamente kunye ne-arhente yokulwa nokuqhekeka. Izinto eziphambili ze-arhente yokulwa nokuqhekeka luhlobo lwe-silica fume, enokugcwalisa iimbobo eziphakathi kwamasuntswana esamente, yenze ii-gels ngeemveliso zokufutha, kwaye iphendule ne-alkaline magnesium oxide ukwenza ii-gels.
Udaka lokuplasta:
Udaka olusetyenziswa kumphezulu wezakhiwo kunye nezinto kunye nomphezulu wezinto ezisisiseko, olunokukhusela indlela yesiseko kwaye luhlangabezane neemfuno zokusetyenziswa, lunokubizwa ngokuba ludaka lokuplasta (okwaziwa ngokuba ludaka lokuplasta).
Ukwakhiwa kwesamente:
Isithako sokudibanisa izakhiwo esiquka izinto zejeli (ngesiqhelo isamente kunye nelayimu) kunye ne-aggregate entle (ngesiqhelo isanti entle yendalo).
Ukugcinwa kwamanzi kwesamente kubhekisa kubuchule besamente bokugcina amanzi. Isamente egcina amanzi kancinci idla ngokopha kwaye yahlulwe ngexesha lokuthuthwa nokugcinwa kwayo, oko kukuthi, amanzi ayadada ngaphezulu aze isanti nesamente zitshone ngaphantsi. Kufuneka ixutywe kwakhona ngaphambi kokuba isetyenziswe.
Zonke iintlobo zeendawo ezisisiseko ezifuna ukwakhiwa kwe-mortar zinokufunxwa kwamanzi okuthile. Ukuba ukugcinwa kwamanzi kwe-mortar akusebenzi kakuhle, ngexesha lokufakwa kwe-mortar, lo gama nje i-mortar exutyiweyo elungele ukudibana ne-block okanye i-base course, amanzi aya kufunxwa yi-mortar elungele ukwenziwa. Kwangaxeshanye, amanzi aya kuphuma kumphezulu we-mortar ejongene nomoya, nto leyo ebangela ukuba amanzi anganeleyo kwi-mortar ngenxa yokulahleka kwamanzi, nto leyo echaphazela ukufuma kwesamente ngakumbi, echaphazela uphuhliso oluqhelekileyo lwamandla e-mortar, nto leyo ebangela ukuba amandla angaphakathi angabi maninzi. Ngokukodwa, amandla okudibana phakathi komzimba we-mortar oqinileyo kunye nesiseko ayancipha, nto leyo ebangela ukuba i-mortar iqhekeke kwaye iwe. Kwi-mortar enokugcinwa kwamanzi okuhle, ukufuma kwesamente kwanele, amandla anokukhula ngokwesiqhelo, kwaye anokudibana kakuhle ne-base course.
Ngoko ke, ukwandisa ukugcinwa kwamanzi kwi-mortar akupheleli nje ekuncedeni ukwakhiwa, kodwa kukwanyusa namandla.
