7 Ngakho-ke, ngesikhathi sokuxuba isivivinyo (ukukhiqiza), inani kufanele lenyuswe ngendlela efanele. Kuphela ngokuguqula umthamo (okungukuthi, ukufinyelela umthamo we-satuanation) ingaxazululwa inkinga yokulahleka okukhulu kwe-slump.

I-8.Emva kokunciphisa inani lezinto zokwakha i-cementional, isilinganiso samanzi-usimende kufanele sibe sebeqinisekiswa ngokwengeziwe ngesikhathi sokukhiqiza. Uma ukulahleka kwe-slump kukhulu, okuwukuphela kwendlela ukukhulisa inani lokuhlanganiswa futhi ungeze ukuphikisana kabili. Ungangezi namanzi ukuxazulula inkinga, ngaphandle kwalokho kuzobangela ukwehla okukhulu kwamandla.

9 Ekulweni kokukhiqizwa, inkomba ye-fluidity (ukunwetshwa) kokhonkolo kufanele kusetshenziselwe ukukala ukusebenziseka kokhonkolo. I-Slump ingasetshenziswa kuphela njengenani lereferensi.

10. Amandla kakhonkolo anqunywa ikakhulu yisilinganiso se-manzi-sing. I-ejenti ye-polycarboxylate ye-polycarbox. izindleko eziphelele. Njengoba izinto ezingavuthiwe ziyashintshashintsha ngaphezulu ngesikhathi sokukhiqiza kunasesikhathini, ukuze zisebenzise kangcono ukusebenza kwemikhiqizo ye-polycarboxylate superplastimizer, ama-admixtures kufanele alungiswe ngendlela yezimo ezisetshenziswayo, izinguquko zokushisa ezikhona, njll. Ekusebenzeni kwe ukhonkolo ngesikhathi sokukhiqiza. Umthamo.

11. Ama-polycarboxboxylic acid acijile ama-ejensi ancishiswe amanzi awakwazi ukuxutshwa nama-naphthalene asuselwa kumanzi ancishisiwe amanzi. Lapho usebenzisa ama-polycarboxyylic acid anchents anchents agents, i-mixer kanye neloli yokuxuba elisebenzisa ama-naphthalene-based an agents asebekhulise ukuhlanzeka, uma kungenjalo i-polycarboxyylic acid e-umenzeli yokunciphisa amanzi ancishisiwe angalimala. Umenzeli oncishisiwe amanzi ulahlekelwa yithonya lawo lokunciphisa amanzi.

12. I-Polycarboxylate Superplastimizer kufanele igweme ukuxhumana kwesikhathi eside ngezinto zensimbi. Kusukela imikhiqizo ye-ejenti ye-polycarboxylate ivame ukuncipha kwamanzi, ukuxhumana kwesikhathi eside nemikhiqizo yensimbi kuzodala ukusabela kancane, okungenza kube mnyama noma kumnyama umbala, okuholela ekwehleni kokusebenza komkhiqizo. Kunconywa ukusebenzisa amabhakede epulasitiki we-polyethylene noma amabhakede ensimbi angenasici ukuze aqinisekise ukuqina kokusebenza.
