摘要
本文简要介绍埋藏在我国26个试验站的18种混凝土及钢筋混凝土材料腐蚀情况的实测结果。取得了二万多个数据,经复核审查数据可靠。在中、碱性土壤中埋设35年的腐蚀数据和酸性土壤中1、3、5年的腐蚀数据,在我国还是首次获得。这对我国基本建设具有重要意义。在此基础上,总结出不同混凝土在不同土壤中的腐蚀规律、钢筋锈蚀规律、主要影响因素、以及硫酸盐对混凝土强度影响等等。这对建立和发展我国混凝土材料环境科学,指导不同混凝土材料的合理使用具有重要意义。
More than 20000 corrosion data of 18 kinds of concrete and reinforced concrete,which were proved to be reliable by experts and authority,have been accumulated from 26 experimental sites.The corrosion data of concrete and reinforced concrete embedded in neutral,alkaline soil for 35 years and embedded in acid soil for 1,3,5 years are first obtained in our country,which have great importance to the capital construction of our country.Based on this,the corrosion regularity of concrete and reinforcement in different soils,the major influential factors and the action regularity of sulphate to concrete strength are summarized in the paper.It is of great significance for establishing and developing the environmental science of concrete and guiding proper use of different concrete in our country.
