chinhu chinoderedza mvura chepolycarboxylate mukongiri yakasimba

Nekukura kweindasitiri yekuvaka ichienda kumabasa epamusoro, simba rayo guru uye kuchengetedzwa kwezvakatipoteredza, zvinodiwa pakushanda kwezvinhu zvekongiri zviri kuramba zvichivandudzika. Kongiri yakasimba zvikuru inoshandiswa zvakanyanya muzvivakwa zvirefu, mabhiriji, zvivakwa zvakakura uye mamwe mapurojekiti einjiniya nekuda kwehunhu hwayo hwakanaka hwemakanika uye kugara kwenguva refu. Semusanganiswa wekongiri yepamusoro wechizvarwa chechitatu,chinhu chinoderedza mvura chinonzi polycarboxylaterave chinhu chakakosha pakugadzira kongiri yakasimba zvikuru nekuti inogona kupararira zvakanyanya uye inodzivirira kudonha kwayo.

1. Hunhu hwekushanda kwemushonga wekuderedza mvura we polycarboxylate

Polycarboxylate water reducer imhando itsva yehigh-performance water reducer yakagadzirwa nekuisa mapoka akawanda anoshanda ane polyether uye acrylic acid sechain huru. Maumbirwo ayo emamorekuru anoumbwa nemapoka makuru ekudzvinyirirwa kwechain uye mapoka e side chain steric blockade, ayo ane dhizaini yepamusoro uye mashandiro. Kana tichienzanisa ne naphthalene yechinyakare kana aliphatic water reducers, polycarboxylate water reducers dzine mabhenefiti akakosha anotevera:

Kudzikisa mvura zvakanyanya: Polycarboxylate water reducer inogona kuderedza mvura neanopfuura 20% nedosi shoma, zvichinyatsoderedza huwandu hwemvura nesimende yekongiri, nokudaro ichivandudza simba rayo.

Kupararira kwakanaka uye kuchengetedza kudonha: Maumbirwo ayo emamorekuru anogona kugadzira jira rakagadzikana pamusoro pezvikamu zvesimende, kuderedza kukwezvana pakati pezvimedu, uye kuchengetedza kuyerera kwakanaka.

Kurasikirwa kwakaderera kwekudonha: Nekugadzirisa kureba kwecheni yemativi uye huwandu hwemamorekuru muchimiro chemorekuru, mashandiro ekuchengetedza kudonha kwekongiri anogona kuvandudzwa zvakanyanya kuti agutse zvinodiwa zvekuvakwa kwenguva refu.

Kuenderana kwakanaka: Polycarboxylate water reducer inogona kuchinjika zvakanaka kumhando dzakasiyana dzesimende nemaminerari admixtures (senge fly ash, slag powder, silica fume), izvo zvinobatsira pakugadzirwa kwecomposite high-performance concrete system.

Yakasvibirira uye ine hushamwari kune nharaunda: Maitiro ayo ekugadzira zvinhu ane hushamwari kune nharaunda, ane zvigadzirwa zvishoma, uye anosangana nezvinodiwa zvekusimudzira nharaunda.

2. Zvinodiwa zvekutanga zvekongiri yakasimba

Kongiri yakasimba inowanzoreva kongiri ine simba rekudzvanya re cubic re C60 zvichikwira. Kuti iwane simba rayo guru, chiyero chemvura nesimende chinofanira kuderedzwa ukuwo ichivimbisa kushanda zvakanaka kwekuvaka (senge kupomba mvura, kuyerera kwayo) uye kugara kwenguva refu. Kuti izvi zviitike, zvakakosha kushandisa zvinoderedza mvura zvinobudirira kuti zvivandudze kushanda kwekongiri, uye zvinoderedza mvura zvinoumba polycarboxylate ndiyo sarudzo yakanaka yekuzadzisa chinangwa ichi.

3. Mabhenefiti e polycarboxylate water reducer mu concrete ine simba guru

Kuvandudza simba rekutanga neranonoka: Polycarboxylate water reducer inoderedza zvakanyanya chiyero chemvura nesimende uku ichichengetedza kuyerera kwakanaka, kuitira kuti simende ive nemvura yakakwana, inovandudza zvakanyanya simba rekutanga neranonoka resimende, uye inosangana nezvinodiwa zvemagadzirirwo ezvivakwa zvakasimba.

Kuvandudza huwandu hwemaumbirwo ekongiri: kuderedza huwandu hwemvura nesimende pasina kukanganisa kushanda zvakanaka, kunobatsira kuderedza capillaries, kuvandudza huwandu uye kusapinda kwekongiri, uye kuwedzera kugara kwayo kwenguva refu.

Kuvandudza mashandiro ekuvaka: Mukongiri yakasimba, musanganiswa unowanzo sviba nekuda kwehuwandu hwakawanda hwesimende. Kupararira kwakanaka kwepolycarboxylate water reducer kunogona kuvandudza kuyerera kwekongiri, kuderedza kubatana, uye kuvandudza kushanda zvakanaka kwekupomba.

Mhedzisiro yekusanganiswa ne mineral admixtures inokosha: polycarboxylate water reducer ine simba rakanaka rekubatana ne admixtures dzakadai se fly ash, slag powder, uye silica fume, izvo zvinobatsira kugadzirisa hunhu hwe concrete, hwakadai sekusimba, kugara kwenguva refu, shrinkage, nezvimwewo.

Deredza mutengo wese: Kunyangwe mutengo weyuniti yepolycarboxylate water reducer wakakwira, kushanda kwayo kwakanyanya kunogona kuderedza kushandiswa kwesimende, kuderedza kushandiswa kwesimba, kuvandudza mhando yeprojekiti, uye kuwana mabhenefiti ari nani ehupfumi.

4. Kuongorora nyaya yekushandisa

Muchirongwa chekuvaka chakakwirira kwazvo, simba rekongiri rinofanira kuva C80, uye rine mashandiro akanaka uye kugara kwenguva refu. Chikwata chepurojekiti chakashandisa polycarboxylate high-performance water reducer, pamwe chete ne silica fume uye slag powder composite admixtures, uye vakabudirira kugadzira kongiri yakasimba yakasangana nezvinodiwa zvekugadzira nekugadzirisa chiyero chemvura nesimende uye saizi yezvikamu. Mhedzisiro yebvunzo inoratidza kuti simba rekudzvanya rekongiri remazuva makumi maviri nemasere rinodarika 85 MPa, uye nguva yekuchengetedza slump inopfuura maawa maviri, izvo zvinosangana nezvinodiwa zvekuvaka nekupomba panzvimbo, uye zvakare zvinoratidza hunhu hwakanaka hwekudzivirira kuomeswa nechando, kudzivirira kuyerera kwemvura uye kudzivirira carbonation.

5. Matambudziko aripo uye nzira dzekuvandudza

Kunyangwe polycarboxylate water reducer ichishandiswa zvakanyanya mukongiri ine simba guru, kuchine matambudziko anotevera mumapurojekiti chaiwo:

Matambudziko ekushanda zvakanaka kwemamwe masimende: Mamwe marudzi esimende anogona kukonzera kuti chinhu chinoderedza mvura chisashande zvakanaka kana kuti kusashanda zvakanaka kwesimbi kuderera, uye kutsvagurudza kuti zvinhu zvigone kuchinjika sei kunodiwa.

Kunzwa kwakanyanya kunzvimbo yekuvaka: Polycarboxylate water reducer inonzwa mamiriro ekunze akadai sekupisa nehunyoro, uye mamiriro ekushandiswa anofanira kudzorwa zvine mwero.

Maitiro ekugadzira zvinhu akaoma uye mutengo wakakwira: Parizvino, mapurojekiti einjiniya ane mashandiro epamusoro achiri ndiwo anonyanya kushandiswa, uye zvakakosha kuderedza mari kuburikidza nekugadzirisa maitiro ekugadzira zvinhu kuti zvifadze vanhu vakawanda.

Kugadzirwa kwepolycarboxylate water reducer kuchatarisa pane zvinotevera: Chekutanga, kuwedzera kugadziriswa kwemamorekuru kuti pave nekuvandudzwa kwekubatana kwekuderedza mvura uye kugona kwayo kuchengetedza mvura; chechipiri, kugadzirwa kweakachenjera anoderedza mvura, akadai semhando inonzwa tembiricha, mhando inononoka kuburitsa mvura, nezvimwewo; chechitatu, kutsvagisa nzira yekugadzira girini uye ine hushamwari kune nharaunda yekusimudzira budiriro inoenderera mberi; chechina, dhizaini yakangwara yekongiri pamwe chete neAI kana big data.

Polycarboxylate inoderedza mvuraYave chinhu chikuru chekugadzira kongiri yakasimba zvikuru nekushanda kwayo kwakanaka. Kuburikidza nekugadzira nekushandisa zvine musoro, haingogone kugutsa zvinodiwa zvakawanda zvekongiri inoshanda zvakanyanya zvemakanika uye kushanda zvakanaka, asiwo inovandudza hunhu hweinjiniya uye kushanda zvakanaka kwekuvaka. Mumamiriro ekusimudzira tekinoroji yekuvaka mune ramangwana, polycarboxylate water reducer ichashandisa kugona kwayo kukuru mumunda wakakura.
