Fly ash is the most mineral residue left over from burning coal by coal-fired power plants. Fly ash pozzolanic, meaning that it has cementitious properties. It is valuable for use in ready-mix concrete as a partial replacement for Portland cement. Shuningdek, it may be used in the manufacture of other building materials such as bricks, kafel, and blocks.
Beton aralashmalarga chivin kulining qo'shilishi qurilish maqsadlari uchun bir qator afzalliklarni beradi. It is also great for the environment. biri uchun, Qolgan chivinlarni poligonga yuborishning hojati yo'q. Yana biri uchun, tsement ishlab chiqarish CO2 chiqindilarini chiqaradigan yuqori haroratli kalsifikatsiya jarayonini talab qiladi. If every pound of fly ash is used to replace cement in concrete, atigi bir funtli CO2 atmosferaga kirishining oldini oladi. Qurilish uchun, tayyor betonga kulni uchiring offers several advantages versus normal Portland cement-only concrete, shu jumladan –
Concrete mixed with fly ash requires less water for production, bu qisqarishga kamroq moyil bo'lgan zichroq mahsulotni yaratadi. Bu uni kuchliroq va yorilish yoki o'tkazuvchanlikka kamroq moyil qiladi. Kamroq o'tkazuvchanlik namlik va yo'l kimyoviy moddalarini ushlab qolish orqali sovuqqa katta qarshilik ko'rsatadi, harorat pasayishi va qisqarishi mumkin.
The spherical shape of fly ash particles helps to facilitate the movement of the concrete, oddiy betonga nisbatan suv kamayganda ham. Bu nasosni osonlashtiradi, joylashtirish osonroq, and easier to mold, va u o'tkir tafsilotlar bilan yumshoqroq ko'rinishni yaratadi.
Tsement tayyor betonning eng qimmat tarkibiy qismidir. Chivin kulini almashtirish vositasi sifatida, it can create a better product that is less expensive to produce. Arzonroq bo'lgan yaxshiroq mahsulot pastki qatorni tomosha qilganlar uchun barakadir. Xom, ishlov berilmagan chivin kulida ko'pincha qoldiq ko'mir char mavjud, yoki uglerod, bu uning ishiga yoki hatto betonda ishlatilish qobiliyatiga ta'sir qilishi mumkin.
The ST uskunalar & texnologiya electrostatic separation process can treat raw fly ash by removing the unwanted residual coal char. The resulting product is a mineral-rich concrete grade, savdo belgisi ProAsh®. STET jarayonini yangi, ham tarixan ishlab chiqarilgan poligonda yoki urib yuborilgan chivin kulida ishlatish mumkin.
