CONCRETE EXPANSIVE ADMIXTURE USING LOW CARBON LOW BURNING CLINKER FOR MANUFACTURING CEMENT

摘要

In the method for manufacturing a concrete expandable material using a low-carbon low-temperature calcined cement clincher according to an embodiment of the present invention, the content of low-grade limestone having a CaO content of 44.0 to 47.0 wt%, and SO 3 which is a by-product of a bituminous coal-fired power plant is 35.0 to 45.0% by weight of the FGD gypsum and rare metals the content of Al 2 O 3 generated in the recovery process is manufactured, including the alumina sludge 65.0 to 75.0% by weight of a source, a calcium sulfo aluminate (4CaO · 3Al 2 O 3 · SO 3 ) pulverizing a clinker for manufacturing cement having a content of 57.0 to 63.0% by weight; and mixing anhydrite and slaked lime powder in the pulverized clinker, wherein the clinker is 20 to 40% by weight, anhydrite 50 to 70% by weight, and slaked lime is 5 to 20% by weight, so that the sum is 100% by weight Including; mixing to make an inflatable material.
