%X 通过废弃石粉单掺以及分别与粉煤灰、矿渣粉复掺，研究废弃石粉对混凝土的收缩性能、抗氯离子渗透性能、抗硫酸盐侵蚀以及抗冻性能的影响. 研究表明：废弃石粉单掺掺量在10%以内，混凝土表现出良好的抗氯离子渗透性；单掺掺量控制在20%以内，混凝土抗冻性能良好，并在一定程度上提高混凝土抗收缩、抗硫酸盐侵蚀性能；复掺总量控制在30%以内时，混凝土各项耐久性能良好.<br>The effects of waste powder on shrinkage，chloride ion penetration resistance performance，resistance to sulfate attack and frost resistance using the waste powder independently and complex mix of waste powder with fly ash and slag were studied. The research shows that when the content of the waste stone powder is less than 10%，the concrete displays good chloride ion penetration resistance performance，when the content of the waste stone powder is less than 20%，itimproves the resistance of concrete shrinkage and sulfate resistance，frost resistance of concrete is good too. The total amount of the admixture is less than 30%，the durability of the waste stone powder concrete is good
