Abstract：Under the same test conditions，the effects of different addition amounts of active components on the strength and water absorption of concrete were studied，and the internal crystallization of concrete matrix was observed by scanning electron microscope. It was found that the active material enables the concrete specimen to obtain good compressive strength and waterproof performance.
Key words：concrete，active material，compressive strength，water absorption
