混凝土中氧化镁安定掺量的研究
Study on balanced content of magnesium oxide in concrete
摘要
Abstract
This paper presents experimental results of concrete material and compares distortions of cement-based materials with different magnesium oxide content.To obtain the balanced contents of magnesium oxide,three test methods were adopted,method of autoclave-treated expansibility of cement paste,method of concrete mortar with light-burned magnesium oxide,and method of autogenic volume change of concrete.Results show that for the same concrete mixture,the balanced content achieved with these methods are different,with its tested value increasing in turn from autoclaving,mortar test to autogenic volume change test.This work provides a basis for farther study and application of concrete with magnesium oxide.关键词
