Lightweight Concrete Additives | High-Performance Foaming Agents for Cellular Concrete
kongiri yekuwedzera mvura inoderedza superplasticizer ikemikari inoshandiswa kuita kuti misanganiswa yekongiri ibude nyore. Inowanikwa sehupfu kana mvura uye inogona kuwedzerwa kumusanganiswa sezvinodiwa pakushanda kwaunoda. Inoshanda nekudzikisa reshiyo yemvura / simende uye kubvumira kusimba kwekongiri yepamusoro nekuderera kuderera. Inogonawo kumhanyisa kana kumisa kongiri kugadzika zvinoenderana nemakemikari ayo anoita. Inogona kushandiswa mune yakakwirira-inoshanda kongiri kunyorera senge pumpability, kuzvisimbisa kongiri (SCC), low permeability uye kunyura kwemvura yakaderera.
Kongiri inosanganiswa iyo inosanganiswa neinoderedza mvura ine kuderera kwakaderera pane vasina ivo. Izvi zvinoita kuti zvive nyore kushanda kongiri nemaoko uye kuchengetedza pamari yebasa. Iyo yemhando yemvura inoderedza musanganiswa inogona kuwedzera kudonha kwekongiri musanganiswa pasina kushandura simende zvirimo..
Mvura inoderedza musanganiswa inogona kushandiswa pamwe chete nezvimwe zvinosanganiswa senge set retarders., air etraining agents, silika fume uye inobhururuka madota. Izvi zvakasanganiswa zvinogona kubatsira kuzadzisa zvinodiwa nekuita kwemapurojekiti akadai semakoramu marefu, high-simba pasi slabs kana abrasion resistant hydraulic structures.
Mukuwedzera pakuderedza mvura, kongiri yekuwedzera senge superplasticizers inogona kushandiswa kune zvimwe zvinangwa senge kudzoreredza yekutanga seti yekongiri kana kuwedzera simba rayo rekuchinja.. Mamwe anowanikwa se chloride-isina set accelerators inogona kushandiswa muprecast kana prestressed kongiri pasina kukanganisa simba rekupedzisira rekongiri.. Mamwe ma hydration control additives anobvumira makondirakiti kuti awane yakanakisa kongiri nekudzora hydration uye simende particle size..
