Umphumela wamanzi anciphisa i-ejenti ekuqhekekeni kwe-shrinkage ukuqhekeka kukakhonkolo wezentengiso:

I-ejenti yokunciphisa amanzi ingukuhlanganiswa okungezelelwa ngesikhathi senqubo yokuxuba kokhonkolo ukuze inciphise kakhulu noma yehlise kakhulu amanzi ukhonkolo, athuthukise amandla kakhonkolo, futhi athuthukise amandla kakhonkolo. Ukuzijwayeza kufakazele ukuthi ngemuva kokungeza ukuncishiswa kwamanzi ku-ukhonkolo, uma kungekho sidingo sokwandisa amandla, inani likasimende lingancishiswa kakhulu, futhi ukuhlanganiswa kokhonkolo kungathuthukiswa. Ngakho-ke, i-ejenti yokunciphisa amanzi iyinto ebaluleke kakhulu yesengezo ngokhonkolo wezohwebo.

Ukuze uphinde uthuthukise izinzuzo zezomnotho ngokhonkolo wezohwebo, abakhiqizi bakhonkolo bathanda ukusebenzisa ama-ejenti ancishisiwe ngamanzi aphezulu anciphisa izakhiwo ukuze athuthukise amandla kakhonkolo noma anciphise inani lokukhiqiza. Eqinisweni, lokhu ukungaqondi okukhulu. Yize ukuncishiswa kwamanzi kunenzuzo ukuthuthukisa amandla acindezelayo kakhonkolo, ukuncishiswa kwamanzi ngokweqile kuzothinta kabi amandla aguqukayo kakhonkolo. Yize inani elifanelekile lokuncishiswa kwamanzi linenzuzo ukunciphisa inani le-shrinkage likakhonkolo, kufanele liphawule ukuthi lapho kuklanywa isilinganiso sokhonkolo, umsebenzi owengeziwe wokungeza umenzeli wokunciphisa amanzi ubhekwe, namanzi Isilinganiso se -Binder ngokuvamile senzelwe ukuphansi. Ukusetshenziswa kwamanzi kuzokhulisa ukumiswa kokhonkolo kokhonkolo futhi kwandise inani le-shrinkage likakhonkolo.

Yize amandla acindezelayo kakhonkolo wezentengiselwano awanciphisi lapho okuqukethwe kwesimende kuncishiswe kakhulu, amandla ashubile ancipha ngokuncipha kwetshe le-cendid censite eqinisweni. Ngenxa yokwehliswa kwenani likasimende, usimende ukhonkolo osimende omncane kakhulu, futhi kuzovela imifantu emincane kakhulu ngokhonkolo. Vele, imifantu emincane inomthelela omncane emandleni acindezelayo kakhonkolo, kepha ithonya emandleni ashubile nezinye izakhiwo zokhonkolo ngeke zibukelwe phansi. Ukwehliswa okukhulu kwezinto zokwakha i-cementional kuzothinta futhi i-modulus ye-elastic kanye ne-creep kakhonkolo, okwenza ukhonkolo ithambekele ngokwengeziwe ekuqhekekeni.

Ukufingqa, lapho kukhiqizwa ukhonkolo wezentengiselwano, izinga lokuncipha kwamanzi ukhonkolo kanye nenani lezinto zokwakha i-cementional kumele zibhekwe ngokuphelele, futhi akukho ukuncishiswa kwamanzi noma ukuncishiswa ngokweqile kwezinto zokwakha i-cementized.
