Research on the Cement Stable Powder and Mixed with Crushed Stone

摘要

This paper has studied the different dosage of cement mixed with different proportions of gravel. Through the compaction and unconfined compressive strength test and economic analysis, and finally determined that the gravel mixed with content is 30% and the cement dosage is 3%. The study also shows that by adding a certain amount of gravel instead of powder is feasible. The same cement doses adding macadam mixture, unconfined compressive strength is higher than stable powder. The study has solved the shortage of raw materials of construction, saving a lot of money, and has important engineering significance.
