摘要
通过正交试验设计,研究机制砂级配与空隙率的关系。通过试验结果与GB/T 14684—2011《建设用砂》级配和空隙率规定,提出企业应在国标下制定自身机制砂石质量标准的重要性。
In this paper,the relation between gradation and void fraction of manufactured-sand d is studied by orthogonal test.According to the test result and the regulation of grade and void ratio of GB/T 14684-2011 sand for construction,it is proposed that enterprises should formulate their own quality standards formanufactured-sand under the national standard.
