1. Material Science uye Functional Mechanisms
1.1 Zvinoreva uye Kurongeka kweChiremera Admixtures
(Lightweight Concrete Admixtures)
Akaremerwa kongiri anosanganisa akasarudzika emakemikari kana emuviri ekuwedzera akagadzirirwa kuderedza density yemasimiti masisitimu uku uchichengetedza kana kuvandudza chimiro uye chinoshanda..
Kusiyana nechinyakare aggregates, Izvi zvinosanganisa zvinopa inodzorwa porosity kana zvinosanganisira yakaderera-density zvikamu mune kongiri matrix., zvichikonzera huremu hwemudziyo kazhinji kubva kubva 800 ku 1800 kg/m TWO, zvakasiyana ne2300– 2500 kg/m³ yekongiri yenguva dzose.
Iwo akakamurwa zvakanyanya mumhando mbiri: kemikari frothing agents uye preformed light-weight incorporation.
Kemikari frothing vamiririri vanogadzira zvakanaka, yakatsiga mapeji emhepo kuburikidza ne-in-situ gasi kutanga– kazhinji kuburikidza nealuminium poda mune autoclaved aerated kongiri (AAC) kana hydrogen peroxide ine catalysts– nepo preformed inclusions inosanganisira yakawedzera polystyrene (EPS) zviyo, perlite, vermiculite, uye hollow ceramic kana polymer microspheres.
Yepamberi misiyano inosanganisirawo nanostructured permeable silica, aerogels, uye kudzokororwa zvakareruka-huremu kuunganidzwa kunobva kumaindasitiri ne-zvigadzirwa zvakaita segirazi rakawedzera kana slag..
Kusarudzwa kwemusanganiswa kunoenderana neinodiwa thermal insulation, stamina, moto kuramba, uye kushanda, zvichiita kuti zvive zvakasiyana-siyana kune zvakasiyana-siyana zvinodiwa zvekuvaka.
1.2 Pore Structure uye Density-Property Relations
Kubudirira kwekongiri inorema-inorema kunonyanya kudzorwa neiyo morphology, saizi kugovera, uye interconnectivity of pores akaunzwa ne admixture.
Maitiro akanaka anosanganisira kupararira zvakaenzana, akavharwa-sero pores ane hukuru pakati 50 uye 500 micrometers, iyo inoderedza kunyura kwemvura uye yekupisa conductivity uchitora mukana wakazara wekuita kwekudzivirira.
Vhura kumusoro kana akabatana pores, uku kuderedza density, inogona kukanganisa kusimba uye kusimba nekubatsira nekunyorova kwekuwana uye nechando-nyungudika kukuvara.
Admixtures inodzikamisa zvakanaka, akaparadzana mabhuru– senge maprotein-based kana artificial surfactants mufoam kongiri– wedzera kugadzikana kwemakanika uye kugona kwekupisa.
Hukama hwakasiyana pakati pe density uye compressive kuoma kwakanyatso kusimbiswa; zvisinei, yemazuva ano admixture maumbirwo anoderedza kutengeserana uku kuburikidza nematrix densification, fiber kusimbisa, uye optimized kurapa regimens.
( Lightweight Concrete Admixtures)
Semuyenzaniso, kubatanidza utsi hwe silica kana dota rinobhururuka pamwe chete nevamiriri vanobuda furo kunonatsa pore framework uye kuwedzera kongiri paste., kugonesa high-simba lightweight kongiri (kusvika pa 40 MPa) zvekushandisa zvekuvaka.
2. Yakakosha Admixture Kind uye Yavo Injiniya Mabasa
2.1 Mafuro Brokers uye Mhepo-Entraining Solutions
Protein-based and synthetic frothing vamiriri ndiyo hwaro hwekugadzirwa kwefoam kongiri, kugadzira mabhuru emhepo akachengeteka anosanganiswa nemuchina mukongiri slurry.
Hutano hweprotein foams, inotorwa kubva kumhuka kana veggie masosi, inopa yakakwira furo chengetedzo uye yakanakira yakaderera-density application (
Cabr-Concrete mutengesi weConcrete Admixture ine pamusoro 12 makore echiitiko mu nano-kuvaka simba kuchengetedza uye nanotechnology kusimudzira. Inobvuma kubhadhara kuburikidza neCredit Card, T/T, West Union uye Paypal. TRUNNANO ichaendesa zvinhu kune vatengi mhiri kwemakungwa kuburikidza neFedEx, DHL, nemhepo, kana nomugungwa. Kana iwe uchitsvaga yemhando yepamusoro Concrete Admixture, ndapota inzwa wakasununguka kutibata nesu uye kutumira kubvunza.
