Mumunda wezvivakwa zvekuvaka, simende chinhu chakakosha chekushandisa, uye optimization yekushanda kwayo kwagara kuri kutarisisa kwekutsvaga. Calcium formate, sechinhu chakajairika chekuwedzera, inoita basa rakakosha mu simende.
1. Kurumidza simende hydration reaction
Calcium formateinogona kumhanyisa zvakanyanya hydration reaction process ye simenti. Mushure mekunge simende yasanganiswa nemvura, iyo calcium ions mu calcium formate inogona kuita nemamineral components se tricalcium silicate uye dicalcium silicate mu simenti kukurudzira kuparara kwemaminerari esimende uye kuumbwa kwe hydration zvigadzirwa. Izvi zvinobvumira simende kuti isvike simba rakakwirira munguva pfupi, inopfupisa nguva yekuisa simende, uye inovandudza kushanda kwekuvaka.
2. Kuvandudza simba rekutanga
Nekuda kwekukurumidza kuita kwecalcium formate pane simenti hydration reaction, inogona kunyatso kuvandudza simba rekutanga resimende. Mukugadzira zvigadzirwa zvesimende senge precast kongiri zvikamu uye zvidhinha zvesimende, kuvandudzwa kwesimba rekutanga kunogona kukurumidzira kudzoka kwefodya uye kuderedza mutengo wekugadzira. Panguva imwecheteyo, kune mamwe mapurojekiti anoda kushandiswa nekukurumidza, sekugadzirisa migwagwa uye kugadzirwa kwenhandare yendege, kuwedzerwa kwecalcium formate kunogona kuve nechokwadi chekuti chirongwa chine simba rakakwana munguva pfupi yekusangana nezvinodiwa zvekushandisa.
3. Kuvandudza kupikisa kwechando kwesamende
Munzvimbo dzinotonhora, zvigadzirwa zvesimende zvinotarisana nemuyedzo wechando-thaw cycles. Kuwedzerwa kwecalcium formate kunogona kuvandudza kusimba kwechando kwe simenti. Inogona kuderedza porosity musimende, kuderedza kupinda uye kutonhora kwemvura mukati mesimende, uye nokudaro kuderedza ngozi yekukuvara kwechando. Pamusoro pezvo, calcium formate inogona zvakare kuwedzera kuwanda kwesimende uye kuwedzera kusimba kwesamende kune chando chinowedzera kushushikana.
4. Kuvandudza kusimba kwekuora kwe simenti
Mune dzimwe nzvimbo dzakakosha, zvigadzirwa zvesimende zvinoda kuve nekudzivirira kwakanaka kwekuora. Calcium formate inokwanisa kuita ne calcium hydroxide mu simenti kuti ibudise zvinhu zvisiri nyore kuita ngura, zvichibva zvanatsiridza kusaonda kwe simenti. Panguva imwecheteyo, calcium formate inogonawo kuderedza kupindira kwe simenti uye kuderedza kukukurwa kwe simenti ne corrosive media.
Calcium formateinoita basa rakakosha musimende mukumhanyisa hydration reaction, kuvandudza simba rekutanga, kunatsiridza kusimba kwechando uye kuwedzera corrosion resistance. Mukugadzira uye kushandiswa kwesamende, kushandiswa kunzwisisika kwe calcium formate kunogona kuvandudza kushanda kwesamende uye kusangana nezvinodiwa zvezvirongwa zvakasiyana.
