Some countries use microsilica fume as an admixture in the production of cement. Canada requires that in cement mixed with microsilica fume, the silicon content in the microsilica fume should be >85%, yonish yo'qotilishi bo'lishi kerak<6%. In addition, Russia, the United States, Japan and other countries also use microsilica fume as a blending material for the production of special cement. Special cement mixed with microsilica fume can be made into dense concrete with a strength 2 to 3 times that of ordinary concrete. It has good wear resistance, corrosion resistance, impermeability, insulation, frost resistance and resistance to chloride ions. Blocking performance, etc.
BHZAD va boshqalar. tsement va mikrosilikat tutunli prekast panellarning torf blokli pollarning muhandislik ko'rsatkichlariga ta'sirini o'rganib chiqdi. Prefabrik panellar va torf pollarining kuchlanish taqsimotini tahlil qilish uchun ular chekli elementlar usulidan foydalanganlar. Natijalar shuni ko'rsatdiki, yig'ma panellar yumshoq torf pollarining mustahkamligini sezilarli darajada yaxshilashi mumkin. va tashish qobiliyati. Mikrosilikat tutuni va polipropilen tolasi tsementga aralashtiriladi. Natijalar shuni ko'rsatadiki, ularni aralashtirish tsementning mustahkamligini, yorilishga chidamliligini, ixchamligini va chidamliligini oshirishi mumkin, ammo sementning suvni singdirish va hajmli sifati pasayadi. OZCAN va boshqalar. 7, 14 va 28 kun davomida bentonit, uchuvchi kul va mikrokremniyli dumanli tsement shlamining matritsaning bir o'qli bosim kuchiga ta'sirini o'rganib chiqdi. Tadqiqot shuni ko'rsatdiki, mikrosilikat tutuni matritsaning bir o'qli bosim kuchini yaxshilashda eng samarali hisoblanadi. parametr ko'rsatkichlari.
Mikrosilikat bug'ining tarkibi qo'shilsa, tsementning mustahkamligi sezilarli darajada oshadi. Microsilica dumanı tsementning ixchamligi va sekant elastik modulini samarali ravishda yaxshilashi va tsementning korroziyaga chidamliligi va siljish xususiyatlarini sezilarli darajada yaxshilashi mumkin. Biroq, tsementning suvni singdirish darajasi va hajmiy sifati kamayadi. Shuning uchun mikrosilikat tutunini tsement tarkibiga qo'shganda, suvni singdirish va hajmli massani kamaytirishga e'tibor berish kerak.
