Abstract: One kind of super high strength concrete, by adding some zeolites to cement, in order to attain the objective of shortening the time of hydration of cement, so that the concrete shows higher initial compressive strength. Zeolites and cement can undergo the Pozzolanic reaction which results in less void content and higher final compressive strength, so we can get super high strength concrete.
