Kudzidza pamusoro pekutsemuka kwekutanga kwesamende dhaka yakasanganiswa nepamusoro inoshanda yekudzikisa mvura
1. Elliptic ring shrinkage cracking test inoratidza kuti naphthalene uye polycarboxylic acid superplasticizers inorebesa nguva yekutanga kupaza kwesamende dhaka., inoderedza kuputika kwekunzwa kwesamende dhaka.
Kana yakakwirira kunyatsoshanda mvura kuderedza mumiririri dosage chikamu panguva imwe chete, ukuru hwekutanga kutsemuka nguva yekurongeka kwesamende: yakasanganiswa> PC simende dhaka yakasanganiswa nesamende dhaka> H – UNF C – UNF simende dhaka> mabhenji masampuli.
Mhedzisiro yekuonekwa, yakakwirira kunyatsoshanda mvura inoderedza mumiririri kuderedza simende dhaka kutsemuka senitivity iri: poly carboxylic acid kirasi> yakakwira yemhando mhando naphthalene akatevedzana> yakajairika naphthalene akatevedzana.
2. Mune yakagadziriswa mvura / simenti reshiyo uye simende paste kunaka, kusanganisa naphthalene series, poly carboxylic acid mhando yepamusoro-soro yemvura inodzikisa mumiriri inowedzerwa mahara shrinkage yesamende dhaka iyo inozowedzerwa nedosage yemhando yepamusoro yekudzikisa mvura mumiririri. . Pasi pemamiriro akafanana emhando yepamusoro yemvura inoderedza agent dosage phase, dhaka resimende 28 d yemahara shrinkage kukosha kwehukuru hweodha: Sanganisa h-unf simende dhaka> sanganisa c-un F simende dhaka> sanganisa PC simende dhaka> referenzi sampuli. Tinogona kuona kubva ipapo, pasi pemamiriro ekuedzwa akafanana, mhedzisiro yemvura yakakwira yekudzikisa agent inodzora vhoriyamu kugadzikana kwesamende dhaka yakafanana pazasi: poly carboxylic acid kirasi > yakajairika naphthalene akatevedzana BBB 0 high concentration naphthalene system.
3. Mukati mechikamu chebvunzo iyi, kusanganiswa kwepolycarboxylic acid kunoshanda kudzikisa mvura kunoderedza hupamhi hwekutsemuka kwesamende dhaka, nepo kusanganiswa kwenaphthalene system kunomhanyisa chiyero chekukura kwehupamhi hwekutsemuka kwesamende dhaka., panguva iyo 28 d yakatokwirira kupfuura iyo yereferenzi sampuli.
4. Pasi pemamiriro ekurapa kwakaoma, kuwedzera yakakwirira-inoshanda-inoderedza mvura mumiririri inovandudza kuchinjika uye kumanikidza simba resimende dhaka re 28 d, uye kuwedzera yakakwirira-inoshanda-inoderedza mvura yepolycarboxylic acid, iyo inonyanya kushanda mukuvandudza simba resimende dhaka re 28 d pane kuwedzera yakanyanya-inoshanda-inoderedza mvura mumiririri we naphthalene system.
Ndeupi musiyano uripo pakati pekudzikisa mvura neretarder?
Mvura inodzikisa mvura imhando yemusanganiswa unokwanisa kuchengetedza kushanda kwenet sement slurry., dhaka nekongiri zvisina kuchinjwa uye zvinogona kuderedza zvakanyanya kuwanda kwemvura inoshandiswa pakusanganisa. Inogona kuvandudza zvakanyanya simba rekongiri uye kuvandudza kusimba kwechando kwekongiri pamwe nekusamira uye kuderedza huwandu hwesimende uye zvichingodaro..
Retarding agent zvakare ndeyemusanganiswa, asi inozononotsa nguva yekumisikidza kongiri pasina pesvedzero iri pachena pasimba rinozotevera. Function: chinangwa chekusanganisa retarder yemunhu mukongiri ndechekuwedzera hydration uye kuoma nguva yesamende, kuitira kuti kongiri nyowani inogona kuchengetedza plastiki munguva yakareba,uye nokudaro gadzirisa nguva yekuisa kongiri itsva.
Cie-China.org ndiyo inotungamira furo kongiri yekuwedzera inopa inopa kongiri inopupuma mumiriri, superplasticizer,foam kongiri simba rekusimudzira kune lightweight kongiri, CLC inovhara. Kana uri kutsvaga superplasticizer, ndapota inzwa wakasununguka taura nesu.
