Foaming Agents muConcrete

Foaming agents ikemikari makomisheni ane yakaderera chaiyo giravhiti inowedzera kupenya kwekongiri. Kazhinji, Foaming agents anoshandiswa pamwe chete neaggregates kuvandudza kushanda kwavo. Vanogonawo kubatsira kuderedza kushanduka kwekongiri panguva yekurapa nekusimudzira hydration uye nekuvandudza pore chimiro chefuro.. Foaming agents anogona kugadzirwa nezvinhu zvakasiyana senge gasi remarara, limestone, gypsum, kubhururuka madota nejecha. Zvisinei, kongiri inoguma ine simba rakaderera rekumanikidza nekuti mavhodhi emhepo anowanzo kudonha [1].

Kuwedzerwa kwefoam stabilizer kana PPF kunogona kuwedzera ma mechanic zvimiro zvefoam kongiri. Zvisinei, akareruka furo kongiri akagadzirwa pamwe nekuwedzera kwefoam stabilizer uye PPF inoratidza kuderera kwe density., Thermal conductivity uye flexural uye compressive simba sezvo huwandu hwavo hunowedzera ne furo agent yekuwedzera kubva pa5wt% kusvika 7wt%. Izvi zvinodaro nekuti huwandu hukuru hwema pores anogadzirwa nekuora kweanopupa agent anogona kutungamira kune yakaipa mhedzisiro pane pore chimiro..

Mukuwedzera kune foam stabilizer uye PPF, kushandiswa kwedota renhunzi kwakaratidzwa kuwedzera simba rekumanikidza uye kupisa kwemafuta ekongiri ane furo.. Izvi zvinodaro nekuti madota enhunzi chinhu chakaderera-density chinotora chikamu mukunyorovesa simende uye inosimudzira chimiro chepore chekongiri ine furo..

Iyo SEM mufananidzo wakapihwa mumufananidzo 4 inoratidza iyo microstructure yefoam kongiri apo WMP yakatsiva silica jecha uye RHA yakawedzerwa kumusanganiswa. Kuwedzerwa kweRHA kwakavandudza chimiro chepore chekongiri nekuwedzera saizi yeCSH gels. Kuwedzerwa kwemarara emarble kwakasimudzirawo chimiro chepore nekuwedzera huwandu hweakakwenenzverwa zvimedu mumusanganiswa..
