再生微粉对混凝土强度的影响研究

摘要

针对废弃混凝土破碎、研磨制备的再生微粉对混凝土抗压、劈裂抗拉的影响进行了研究,试验结果表明,掺有再生微粉的混凝土的抗压强度、劈裂抗拉强度均能满足实际工程应用的要求。%This paper studies the impacts of recycled ultrafine powder grinded with waste conerete on pressure resistence of concrete and tensile splitting strength.Results show that the compressive strength and split tensile strength of recycled fine-powder concrete meet the requirements of practical engineering application.
