机制砂的制备及在混凝土中的应用

On application of machine-made sand preparation in concrete

对机制砂的生产、技术指标进行了分析评定,并通过室内试验得出了机制砂完全可以替代天然砂配制出符合设计要求的高品质混凝土的结论,以推广机制砂在混凝土工程中的应用。

The paper points out the analysis evaluation for the production of the machine-made sand and its technological parameters,and concludes the natural sand can be fully replaced machine-made sand to produce the high qualified concrete adhering to the design requirement,so as to extend the application of the machine-made sand in concrete project.
