ew ndi apamwamba zofunika ntchito konkire.Kuyambira Kukwezeleza konkire admixtures mu 1940s, chitukuko chake osati anasintha kapangidwe mkati mwa oumitsa konkire ku tinthu ting'onoting'ono ndi submicroscopic misinkhu, komanso anasintha kapangidwe konkire mwatsopano mu ndondomekoyi. .Kusakaniza konkriti, komwe kumadziwikanso kuti dispersant kapena plasticizer, ndikomwe kumagwiritsidwa ntchito kwambiri komanso kofunikira kwambiri.

Kukonzekera konkire mwatsopano ndi katundu otaya wabwino, mawonekedwe viscous amene amachepetsa otaya pakati pa simenti particles ayenera disassembled, kuti particles simenti akhoza omwazika mokwanira mu sing'anga madzi.Pali zinthu zambiri zomwe zimakhudza kuphatikizika kwa simenti, monga kuchuluka kwa mchere wa simenti, mawonekedwe ndi kukula kwa tinthu tating'ono ta simenti, kukhulupirika kwa mineral crystallization, komanso magwiridwe antchito ndi zinthu zachilengedwe.Zomwe zili pamwambazi mwachindunji kapena mwachindunji zimayang'anira kukhazikika kwa tinthu ta simenti mu slurry.Osiyana sing'anga zinthu zingasinthe mtengo wa magetsi mlandu wa particles simenti mu slurry, ndiye kusintha electrostatic repulsion pakati pa particles.

Pamene kuchuluka koyenera kwa konkire kumawonjezedwa ku konkire yatsopano, mfundo za particles za simenti zimawonjezeka, ndipo kuthamangitsidwa kwa magetsi pakati pa particles simenti kumawonjezeka kwambiri, zomwe zimapangitsa kuchepa kwa kukhuthala kwa konkire mwatsopano, zomwe zimalimbikitsa bata la simenti. dongosolo lonse lobalalika.kuchuluka, ndipo liquidity anakula.

Nthawi zambiri, kuwonjezera koyenera konkriti admixture mu simenti phala akhoza kulimbikitsa mwatsopano konkire kusonyeza amphamvu thixotropy.Ichi ndi chifukwa mapangidwe solvated filimu wosanjikiza pamwamba pa simenti particles adsorbed kwa madzi kuchepetsa wothandizira ndi kuwonjezeka angathe.Ngati pali kugwedezeka pang'ono, kumawonetsa madzi abwinoko.The thixotropy wa konkire mwatsopano popanda superplasticizer ndi ofooka kwambiri.
