6. Ingxaki yokungasebenzeki kakuhle kwekhonkrithi entsha
Iipropati zokusebenza zekhonkrithi entsha ziquka ukumanzi, ukudibanisa kunye nokugcinwa kwamanzi. I-Fluidity ibhekiselele ekukwazini komxube wekhonkrithi ukuhamba kwaye ugcwalise i-formwork ngokulinganayo kunye nokuxinana phantsi kwesenzo sobunzima bawo okanye ukungcangcazela komatshini. Ukubambisana kubhekisela kubumbano phakathi kwamacandelo omxube wekhonkrithi, onokuthi ugweme i-stratification kunye nokwahlula ngexesha lenkqubo yokwakha. Ukugcinwa kwamanzi kubhekisela ekukwazini komxube wekhonkrithi ukugcina amanzi, oko kunokuphepha ukuphuma kwegazi ngexesha lokwakha. Ukulungiswa kwangempela kwekhonkrithi, ngakwesinye icala, kwikhonkrithi yamandla aphantsi, inani lezinto ze-cementitious alikho phezulu kwaye umlinganiselo we-binder wamanzi mkhulu. Ukongeza, umgangatho odibeneyo wekhonkrithi enjalo udla ngokuba mbi. Ukusetyenziswa kwe-PCE kunye nezinga eliphezulu lokunciphisa amanzi ukulungiselela ikhonkrithi enjalo ilungele ukuhlukana kunye nokuphuma kwegazi komxube; kwelinye icala, i-concrete ephezulu yamandla elungiselelwe ngokusebenzisa i-samente enamandla aphantsi, ukwandisa ubuninzi bezinto ze-cementitious kunye nokunciphisa umlinganiselo we-binder wamanzi uthambekele kwi-viscosity ephezulu yekhonkrithi, u-fluid umxube ongalunganga kunye nesantya sokuhamba kancinci. Ke ngoko, i-viscosity ephantsi kakhulu okanye ephezulu kakhulu yomxube wekhonkrithi iya kukhokelela ekusebenzeni kakubi kwekhonkrithi, ukunciphisa umgangatho wokwakha, kwaye kungathandeki kakhulu kwiipropati zoomatshini kunye nokuqina kwekhonkrithi.
