随着国民经济的发展,近年来我国电力工业发展迅速,全国好多省市兴建、扩建和改建了燃煤电厂,造成粉煤灰的排放量急骤上升,带来了取置粉煤灰矛盾的尖锐化,预计到1990年将达到7000万吨,而目前我国粉煤灰利用率仅20％多一点。为了解决粉煤灰的出路,急需开拓经济实用的、大批量用灰的新途径,对提高粉煤灰的利用率和使用价值大的项目,需作一定的深化研究。而从我国的公路建设发展来看,正在兴建和筹建的高(快)速公路数十条。我市已通车和
With the development of the national economy, the power industry in our country has been developing rapidly in recent years. Many provinces, cities and cities across the country have built, expanded and rebuilt coal-fired power plants, resulting in a sharp rise in fly ash emissions. This has brought sharper contradictions of fly ash It is estimated that by 1990 it will reach 70 million tons, but at present, the utilization rate of fly ash in China is only slightly more than 20%.
