Title: Shelf life of alkali activated cement: Effects of storage condition and duration

Journal Article · · Construction and Building Materials

Hydraulic cements based on the alkali aluminosilicate chemistry tend to be more reactive than Type I Portland cement. An experimental investigation was conducted in order to evaluate the effects of storage in air and in sealed condition on the properties and performance of alkali aluminosilicate cements. Different storage durations up to 28 days were considered in this experimental study. Hydraulic cements were evaluated based on their morphology, chemistry and mineralogy, hydration kinetics, strength development characteristics, and microstructure of the resultant hydration products. The early-age hydration kinetics and strength development characteristics of the alkali aluminosilicate cement were found to be altered by storage, especially when the cement was exposed to air. Older cements also produced hydration products that were more susceptible to microcracking when dried under vacuum. Longer-term strength development characteristics of cements were less influenced than their shorter-term strength development characteristics with duration of storage in sealed or exposed condition.
