Investigation for Strength and Durability of Mortar Using Dry Sludge Powder
In recent years, reducing environmental impact is required in all industries.Therefore, the dry sludge powder has attracted a great deal of attention in the construction industry.Dry sludge powder is a method to reuse returned concrete.It is hoped that this can be reuse as replace cement.In the previous study, it is reported that specific surface area and density are different in the dry sludge powder according to the processing time at the production.We need to investigate strength and the durability to utilize dry sludge powder effectively because these are necessary for construction materials.In this study, authors inspected the strength developing property and durability of mortar using the dry sludge powder which different processing time.As a result, the strength development property obeys the progress of hydration reaction.The carbonation depth of mortar using the dry sludge powder became larger than mortar using Ordinary Portland Cement.On the other hand, the salt penetration depth become smaller than mortar using the Ordinary Portland Cement.
