配合比的主要参数对外掺MgO混凝土自生体积变形的影响
Influence of mix factor on autogenic volume deformation of concrete mixed with magnesium oxide
摘要
Abstract
In this work, the influence of water-cement ratio, MgO content, fly-ash content, grading of aggregate and so on, on autogenic volume deformation of concrete mixed with light-burned magnesium oxide were tested. Results show that the autogenic volume deformation becomes greater when water-cement ratio or/ and MgO content is increased. And this volume deformation is higher at early ages and lower at later ages if fly-ash is added, and it also varies considerably with the maximum aggregate size. The results are practically significant to further study and application of concrete mixed with magnesium oxide.关键词
