宁津甲子山地区正长岩体作为混凝土骨料的适宜性评价

Suitability Evaluation of Syenite Rock Mass Used as Concrete Aggregate of Jiazishan Area in Ningjin County

摘要:

砂石骨料在混凝土中起着极其重要的作用，其质量关系工程寿命的大计。该文选择山东省荣成市宁津甲子山地区正长岩体作为研究对象,对该地区正长岩体作为混凝土骨料的适宜性进行了评价研究。通过野外实地调查及大量的分析测试数据对该地区三叠纪宁津所序列甲子山单元、东山单元、朝阳洞单元岩石进行了分析研究，确定其用作粗细骨料的适宜性，并提出了开采的建议。

Abstract:

Sandstone aggregate plays an extremely important role in the concrete. Its quality will affect the project life. In this paper, selecting syenite rock mass of Jiazishan area in Ningjin county in Rongcheng city of Shandong province as the research object, suitability of syenite rock mass as concrete aggregate in the region has been evaluated. Through field investigation and analysis of a large number of test data in the region, rocks of Jiazishan unit, Dongshan unit and Chaoyangdong unit of Triassic Ningjinsuo sequence sequence have been analyzed and studied, suitability of rocks which are used as coarse and fine aggregate has been determined, and some suggestions of exploitation has been put forward.
