CONSTITUTION: The cement admixture composition comprises 20-40 wt% of stainless slag; 20-40 wt% of the burned product from a combined heat and power plant; 5-40 wt% of furnace slag fine powder; and 5-20 wt% of paper ash. Preferably the stainless slag, the burned product from a combined heat and power plant, the furnace slag fine powder and the paper ash have a particle size of 3,000-5,000 cm2/g, respectively. The cement secondary product is prepared by substituting 10-30 wt% of the total amount of cement with the cement admixture composition.</p> |
