摘要
电石灰是工业废料,经实验证明其主要成分与消解后石灰相同,且钙镁含量符合公路建设的要求,并对10％、12％、14％、16％、18％、20％几种电石灰剂量进行组成设计实验,经过实验结果分析后,采用16％电石灰剂量进行试铺,各项指标均达到标准的要求。用电石灰代替石灰用于路面基层,不仅能节省大量的建设资金;减少优质石灰岩的开采,保护生态环境;减少电石灰排放占用的土地,减少其对土地和空气的污染;也可降低企业的生产成本,提高经济效益。
As an industrial waste material, calcium carbide ash is experimentally proved of same main ingredients with lime resolved and its contents of calcium and magnesium are in line with the requirements of highway construction. The experiment for ingredient design has been performed for calcium carbide ash with a dose of 10% , 12% , 14% , 16% , 18% and 20% respectively. According to the analysis of the experiment results, all indexes can meet the standard when performing the test pavement with 16% calcium carbide ash. To substitute calcium carbide ash for lime on the pavement base can save construction capital in large sum; can protect ecological environment with the reduction of exploiting quality limestone; can reduce its pollution to land and air through releasing the land used for calcium carbide ash discharge. Meanwhile, in this application, the economic benefits can be raised through lowering the enterprises'production cost.
