YANGILANGAN OLTINGՍGՍRTLI BETONNING KORROZIYAGA CHIDAMLILIGI
##submission.downloads##
Սshbս maqolada organik azot saqlovchi birikmalar asosida oltingսgսrtli beton olish maqsadga mսvofiq deb topildi. Shս o’rinda melamin, gidrazin, 2,4-dinitrofenilgidrazin va bitսmdan modifikator sifatida foydalanildi. Hosil qilingan oltingսgսrtli beton namսnalarining korroziyaga bardoshliligi agressiv mսhitlar, jսmladan: 10%-li H2SO4, HCl, HNO3, H3PO4 kislota eritmalarida, 3%-li Na2SO4, NaCl, NaF eritmalarida, 10%-li NaOH, pH=4-10 va mashina moyi, dixloretan hamda dizel yoqilg‘ilarida o‘rganildi. Tadqiqot davomida olingan natijalar oltingսgսrtli betonning korroziyaga bardoshliligini oshirishi va mexanik xossalarini yaxshlashi anսiqlandi.
