尺寸效应对再生混凝土性能的影响
Influence of size effect on properties of recycled concrete
摘要
Abstract
Size effect is the inherent characteristics of quasi-brittle materials. The waste concrete components were manufactured as raw material to get recycled coarse aggregate. Then the recycled coarse aggregate was used as main raw material to prepare recycled concrete. The concrete specimens, of which the replacement ratio of recycled coarse aggregate were 0, 30%, 50%, 80%and 100%, were used as research objects respectively. The influence of the size effect on strength properties and durability of recycled concrete were determined respectively. The test results were analyzed comprehensively to obtain the basic laws of size effect on the strength properties and durability of the recycled concrete. The objective of the study is to provide experimental basis for the application of recycled concrete in engineering construction.关键词
