Lightweight Concrete Additives | High-Performance Foaming Agents for Cellular Concrete
Mushonga wemakemikari weanopupira mumiririri wakakosha pakuona kushanda kwekongiri. Iyo chemistry yeanopupa agent inogona kukanganisa ma mechanical properties uye thermal conductivity yekrete.
Mvura kune simenti ratio (w/c) ine simba rakakosha pane microstructure yefoam concrete. Kana w/c reshiyo iri pasi pemuganho wakakwana, akaonda-akavezwa uye asina kurongeka furo anoumbwa, zvichiita kuti simba rekumanikidza rekongiri riderere. Mukupesana ne, apo w/c chiyero chiri pamusoro pemuganho wakakwana, mabubbles ari nyore kubatana uye ma pores makuru anoumbwa.
Superplasticizers anowanzo shandiswa mufoam kongiri kudzikisa mvura kune simende ratio, uye chengetedza mvura inogutsa panguva yekugadzirwa kwefuro. Izvi zvinoderedza kudiwa kwemvura, inovandudza kushanda uye inowedzera simba rekumanikidza refoam concrete.
Fly ash [41] inogona zvakare kushandiswa mufuro kongiri kuvandudza kushanda kwayo uye kupisa conductivity. Kudyidzana pakati pedota renhunzi neanopupa anogona kuvandudza simba rayo rekumanikidza uye chimiro chepore, sezvakaratidzwa muchidzidzo. Uyezve, kusanganisirwa kwedota renhunzi mune furo kongiri kunogona kukonzera diki pore saizi uye yakakwirira yekumanikidza simba..
Fibers dzinogonawo kuwedzerwa kune foam kongiri kuti iwedzere kunyudzwa kwayo kwemvura. Fibers dzakaita se sugar cane pulp fibers dzine simba rekutora mvura rakakwirira kudarika jecha, saka vanogona kuwedzerwa kune furo kongiri kuitira kuti iwedzere kushanda kwayo uye simba.
Kugadzikana kweiyo cellular lightweight kongiri kunoenderana nerudzi rweaggregate inoshandiswa. Kushandisa yakadzokororwa kongiri aggregate pachinzvimbo chejecha rakanaka kunogona kuvandudza zvakanyanya kugadzikana kweiyo cellular lightweight kongiri.
