【 摘 要 】

To find a way to solve the growing shortage of natural raw materials in building industry, this research adopted the method to fabricate green concrete by using as raw material instead of traditional natural stone and sand. Comparison tests like flexual strength, compressive strength and freeze-thaw resistance were carried out. By the introduction of new type cement, both the flexual strength and compressive strength of this kind of green concrete of 28d could meet the requirement of concrete standard. And green concrete showed a better freeze-thaw resistance than that of Ordinary Portland cement concrete. The microstructure of green concrete and common concrete were also investigated by a digital microscope.
