I-Superplasticizer

Concrete Superplasticizer Uhlolojikelele

Isinciphisi samanzi siyingxube kakhonkolo enganciphisa inani lamanzi okuxuba ngenkathi igcina ukuwohloka kokhonkolo ngokungaguquki.. Ingxube kakhonkolo inomphumela wokuhlakaza ezinhlayiyeni zikasimende, engathuthukisa ukusebenza kwayo, ukunciphisa ukusetshenziswa kwamanzi kweyunithi, ngcono fluidity ingxube ukhonkolo; noma unciphise ukusetshenziswa kukasimende weyunithi futhi wonge usimende.

Types of water reducers

According to performance, it can be divided into ordinary water reducer, high-efficiency water reducer, and high-performance water reducer.
1) Ordinary water reducer refers to an admixture with a water reduction rate of not less than 8% under the condition that the slump of concrete is basically the same.

2) High-efficiency water reducer refers to an admixture with a water reduction rate of not less than 14% under the condition that the slump of concrete is basically the same.

3) High-performance water reducer refers to an admixture with a water reduction rate of not less than 25% under the condition that the slump of concrete is basically the same. Compared with high-efficiency water reducers, it has good slump retention performance, small drying shrinkage and certain air entrainment performance.

Due to the important contribution of high-efficiency water reducer to concrete modification, ukusetshenziswa kwayo sekube impumelelo yesithathu emlandweni wokuthuthukiswa kokhonkolo ngemuva kokhonkolo oqinisiwe kanye nokhonkolo ocindezelwe, okwenze ukhonkolo ukuthi uthuthuke kusukela ekuthelweni kwamanuwali kwasekuqaleni noma ukuthela ithangi elilengayo kuye ekwakheni kokumpompa, ukonga abasebenzi, ukuthuthukisa ukusebenza kahle komsebenzi, ukuqinisekisa izinga, eqeda umsindo, nokwenza igxathu elikhulu ezingeni lobuchwepheshe kanye nezinga lokwakha likakhonkolo.

Indlela yokusebenza yesinciphisi samanzi

1) Ukuhlakazeka

Ngemuva kokuthi usimende uhlanganiswe namanzi, udaka lukasimende lwakha isakhiwo se-flocculation, futhi 10% ku 30% wamanzi okuxuba ahlanganiswe ezinhlayiyeni zikasimende futhi akakwazi ukubamba iqhaza ekugelezeni kwamahhala kanye nokugcoba, ngaleyo ndlela kuthinte uketshezi lwengxube yekhonkrithi. Lapho isinciphisi samanzi sengezwa, ama-athomu anciphisa amanzi angakwazi ukuqondiswa endaweni yezinhlayiya zikasimende ukuze izinhlayiya zikasimende zithwale inani elifanayo. (ngokuvamile ukushaja okunegethivu), ukwakha umphumela we-electrostatic repulsion, okwenza izinhlayiya zikasimende zihlakazeke zodwa, isakhiwo se-flocculation ukuze sihlakazeke, futhi ukhulule ingxenye egoqiwe yamanzi ukuze ibambe iqhaza ekugelezeni, ngaleyo ndlela andise fluidity ingxube ukhonkolo.

2) Umphumela wokugcoba

Iqembu le-hydrophilic ku-reducer yamanzi liyi-polar kakhulu. Ifilimu ye-adsorption yokunciphisa amanzi ebusweni bezinhlayiya zikasimende ingenza ifilimu lamanzi elincibilikisiwe elizinzile elinama-molecule amanzi.. Le filimu yamanzi inomphumela omuhle wokugcoba futhi inganciphisa ngempumelelo ukumelana nokushelela phakathi kwezinhlayiya zikasimende ukuze uketshezi lukakhonkolo luthuthuke nakakhulu..

3) Isithiyo se-steric

Amaketanga aseceleni e-hydrophilic esakhiweni sokunciphisa amanzi anwebeka esixukwini esinamanzi futhi akhe ungqimba lwe-hydrophilic lwe-dimensional adsorption logqinsi oluthile endaweni yezinhlayiya zikasimende ezikhangisiwe.. Lapho izinhlayiya zikasimende ziseduze, izingqimba ze-adsorption ziqala ukudlulana, leyo, ukuthikamezeka kwesteric kwenzeka phakathi kwezinhlayiya zikasimende. Ukugqagqana okwengeziwe, i-steric repulsion kanye nesithiyo esikhulu sokubumbana phakathi kwezinhlayiya zikasimende ukuze ukhonkolo ulondoloze ukuwohloka okuhle..

4) Umthelela okhishwa kancane wamaketango aseceleni e-copolymer

Ngesikhathi sokulungiswa kwezinciphisi zamanzi ezintsha, njengezinciphisi zamanzi ze-polycarboxylic acid, amanye amaketanga aseceleni axhunyelelwa kuma-molecule wesinciphisi samanzi. Amaketanga aseceleni awakwazi nje ukuhlinzeka ngomphumela wesithiyo esiqinile kodwa futhi anqanyulwe kancane kancane endaweni ephakeme ye-alkalinity ye-cement hydration., ikhipha i-polycarboxylic acid enomphumela wokuhlakaza ukuze kuthuthukiswe umphumela wokuhlakazeka kwezinhlayiya zikasimende futhi ulawule ukulahleka kokuwohloka..

Kungani ukhonkolo udinga ukunciphisa amanzi?

Ipharamitha eyinhloko yesilinganiso sokuxuba ukhonkolo isilinganiso samanzi nosimende, leyo, isilinganiso samanzi ku-cementitious material. Ukuphakama kwesilinganiso samanzi nosimende, ngcono ukusebenza kokhonkolo omusha wepulasitiki, kulula ukwakha, kodwa amandla kakhonkolo aphansi. Ukuze kuxazululwe lokhu kungqubuzana, isinciphisi samanzi sidinga ukwengezwa ukuze kuthuthukiswe amandla ngaphandle kokudela ukusebenza kahle noma ukunciphisa umthamo usimende ngenkathi kugcinwa ukusebenza namandla..

Umsebenzi obalulekile wesinciphisi samanzi ukunciphisa ukusetshenziswa kwamanzi kokhonkolo, futhi ingenye yezinto ezibalulekile zokusetshenziswa kwezinto zikakhonkolo. Amandla kakhonkolo ahlobene eduze nesilinganiso samanzi nosimende. Ekuweni okuthile, kuncane ukusetshenziswa kwamanzi, amandla aphezulu. Ukwengeza isinciphisi samanzi kunganciphisa ukusetshenziswa kwamanzi kuyilapho kugcina ukuwohloka kungashintshile, ngaleyo ndlela kuthuthukisa amandla kakhonkolo.

Ebangeni lamandla aphansi ngaphansi kwe-C30, ukusetshenziswa komshini wokunciphisa amanzi kunganciphisa ukusetshenziswa kukasimende, ukunciphisa izindleko, futhi uthuthukise ukusebenza kokhonkolo wepulasitiki.

Ebangeni lamandla aphakathi nendawo lika-C40 kuya ku-C50, isinciphisi samanzi ngokuvamile siyadingeka ukuze kuqinisekiswe ukusebenza kahle (ukupompa) namandla kakhonkolo.

Okwebanga lamandla aphezulu ngaphezu kwe-C50, ngaphandle kokusebenzisa isinciphisi samanzi esisebenza kahle kakhulu noma esisebenza kahle kakhulu, ukhonkolo ngokuyisisekelo awunakho ukusebenza futhi ukhonkolo ofakwe endaweni kunzima ukwakha.

Ukhonkolo opompayo kufanele uhlanganiswe ne-ejenti yokupompa noma isinciphisi samanzi, kanye nezixube zamaminerali kufanele kwengezwe; isinciphisi samanzi esisebenza kakhulu esinezinga lokunciphisa amanzi elingekho ngaphansi 25% kufanele isetshenziselwe ukhonkolo oqinile ngaphezu kwe-C60; izingxube zamaminerali kanye nesinciphisi samanzi esibeka kancane kufanele kwengezwe kukhonkolo yevolumu enkulu.
