摘要
天然煤矸石由于活性较低,严重制约其在水泥生产中的应用,而煅烧热激活是激发煤矸石活性的一种有效手段.通过对其活化温度、煅烧时间、冷却方式、经济效益、掺入矿物微粉改性等六个方面进行煤矸石活化研究,有效提高了煤矸石活性和各项工作性能.
Abstract
Due to the low activity of coal gangue,its application in practical production is severely restricted,and calcination heat activation is an effective means to stimulate the activity of coal gangue.In this paper,through the modification of its activation temperature,calcination time,cooling method,economic benefit,add-ing mineral powder modification,such as five aspects,effectively improve its activity,practical application ef-fect is good.
