摘要
随着日益增长的建筑市场需求,天然骨料供需不平衡的现象越来越严重。本文以山东省乳山市南黄地区黄垒河河砂为调查研究对象,对该地区河砂作为混凝土天然骨料的可行性进行了分析研究。经过野外调查、采样及试验测试、综合分析等,认为河砂质量较好,所测各项指标全部可以满足C60混凝土技术要求,开发技术条件优越,加工技术条件简单,同时提出了下一步开采和利用的意见建议。
With the increasing demand of construction market,the imbalance between supply and demand of natural aggregate is becoming more and more serious.Based on the investigation of Huanglei river sand in south yellow area of Rushan,Shandong Province,this paper evaluates the feasibility of using river sand as natural aggregate of concrete.Through field investigation and a large number of experimental test data,the river sand in this area has been studied and tested in many aspects,such as petrology,petrography,geochemistry and rock material test.All the tested indexes can meet the technical requirements of C60 concrete,and can be used to prepare natural aggregate of concrete above C60.At the same time,some suggestions are put forward for the further exploitation of river sand in this area.
