一、引言据经济日报载:“以煤粉为燃料的火力电厂生产的粉煤灰,正以日益迅猛的速度威胁着我们有限的国土和良田.”“从现在起到本世纪末,我国火力发电而产生的粉煤灰累计将达6亿吨,届时,占地面积将增加50万亩,并将严重污染环境,有关专家学者呼吁,变废为宝,化祸为福,加快开发利用粉煤灰,……”因此,加快粉煤灰的开发利用不仅利国利民,造福子孙,而且具有显著的经济效益,社会效益和环境效益。我们研究试制的粉煤灰硅酸盐微孔夹芯砖,就是这方面的一个偿试。
I. INTRODUCTION According to the Economic Daily, “Pulverized coal ash produced from coal-fired thermal power plants is threatening our limited land and fertile land at an increasingly rapid rate.” “From now to the end of this century, China’s thermal power generation The accumulated amount of fly ash produced will reach 600 million tons. By then, the area will increase by 500,000 mu, and the environment will be seriously polluted. Experts and scholars have called for turning waste into treasure, blessing for disasters, and accelerating the development and utilization of pulverized coal. Gray, ... "Accelerate the development and utilization of fly ash not only to benefit the country and benefit the people, but also to benefit future generations. It also has significant economic, social and environmental benefits. We study the trial of fly ash silicate microporous sandwich bricks, is a test in this regard.
