Abstract：This paper uses four light burned magnesia samples with different activity as the research object,first studies the influence of storage time on the light burned magnesia hydration activity,loss on ignition,expansion character and discuss shelf life of the different samples. Experimental results show that:during 12 months,storage time had no effect on the reactivity of light burned magnesia,but had great effect on the loss and expansion behavior of high active magnesia,and had less impact on the loss and expansion behavior of low active magnesia. When the expansion behavior of light burned magnesia is assured,taking the loss on ignition of samples after storage for certain period as the indicator,M50 and M100 shelf life is 6 months,M150 shelf life is 9 months,M250 shelf life is 12 months. The larger reactivity time of samples,the longer shelf life of light burned magnesia.
