Concrete hollow blocks yave ibwe repakona mukuvaka kwemazuva ano, ichipa kutendeseka kwechimiro uye dhizaini inoshanduka. Chimwe chezvakakosha zvinokonzeresa kukwidziridzwa kwemaitiro emabhuraki ayakubhururuka madota . Kubva mukupisa kwemarasha mumagetsi emagetsi,fly ash inoshanda akati wandei akakosha mabasa mukugadzira kongiri hollow blocks . Ichi chinyorwa chinoongorora mabasa akakosha anoitwa nenhunzi madota muzvinhu zvekuvaka izvi.
▶ Kuvandudza Kushanda:
Fly ash inoshanda se pozzolanic material, zvichireva kuti inogona kuita ne calcium hydroxide pamberi pemvura kuumba simentitious compounds. Iyi pfuma inovandudza kushanda kwekongiri musanganiswa. Muchirevo chekrete hollow blocks, kuiswa kwekubhururuka madotainofambisa musanganiswa wakapfava uye unogoneka, uchigadziranyore kuumba uye kuumbazvidhinha panguva yekugadzirwa.
▶ Kuvandudza Simba uye Kusimba:
Rimwe remabasa ekutanga ekubhururuka kwedota mukongiri maburi mabhuroko kugona kwayokuwedzera simba rekumanikidza zvezvinhu. Iyo pozzolanic reaction pakati pe fly ash uye calcium hydroxide inoguma mukuumbwa kwezvimwe zvigadzirwa zve simenti, zvichipa kune kusimba kwese kwezvivharo. Uku kuvandudzwa kwesimba kunoshandura kuwedzera kusimba, kuve nechokwadi chekuti zvidhinha zvinogona kumira nekuoma kwezvimiro zvemitoro uye mamiriro ezvakatipoteredza.
▶ Kuderedza Kupisa kweHydration:
Kupisa kunogadzirwa panguva ye hydration process ye simenti kunogona kuve kunetseka, zvichitungamira mukupisa kwekupisa mumahombe kongiri zvimiro. Fly ash inoderedza nyaya iyikuderedza kupisa kwe hydration . Mune zvivharo zvekongiri, izvi zvinonyanya kubatsira sezvo zvichibatsira kudzivirira kukura kwekutsemuka uye kuve nechokwadi chekugara kwenguva refu kwemaitiro ezvivharo.
▶ Kuwedzera kusakwana:
Fly ash ine chirevo chekutaura pane porosity yekrete. Nekuzadza ma voids uye nekugadzira yakawedzera kurongedzerwa matrix, nhunzi madota inobatsira mukuvandudza kusamira. Izvi zvakakosha kune kongiri hollow blocks, kunyanya mumashandisirwo uko kupokana nekupinzwa kwehunyoro kwakakosha.Iyo yakakwidziridzwa impermeability inobatsira kuchengetedza zvivharo kubva kumhedzisiro yemamiriro ekunze uye kuwedzera hupenyu hwavo.
▶ Kubatsira Mukuvaka Kunoenderera:
Incorporatingkubhururuka madota mumabhuroko ekongiri maburi anowirirana nemaitiro ekuvaka anoenderera mberi. Nekushandisa chinobuda mukupisa kwemarasha icho chinganzi imarara, indasitiri yekuvaka inoderedza kukanganisa kwayo kwezvakatipoteredza. Izvikwete cheteinowedzera chimiro chezvakatipoteredza chekugadzirwa kwekongiriasiwoinotsigira pfungwa yehupfumi hwedenderedzwa mukuvaka.
Fly ash inoita basa rakawanda uye rakakosha mukugadzira kongiri maburi mabhuroko. Kubva pakuvandudza kushanda uye kuwedzera simba kusvika pakubatsira kusimba, mabasa ayo akasiyana uye ane simba. Sezvo indasitiri yekuvaka ichienderera mberi kukoshesa kushanda zvakanaka, kusimba, uye mutoro wezvakatipoteredza, kubatanidzwa kwekubhururuka madota mukongiri maburi mabhuroko anomira pachena semhinduro inotarisisa uye inoenderera. Kugashira mabasa aya hakungobatsiri kuita kwezvibhuroko chete asi kunobatsirawo mukushanduka kwemaitiro ekuvaka kune ramangwana rakagadzikana.
