矿粉在抗折强度5.0 MPa的C35路面混凝土中的应用

摘要

以实际项目为例，研究了矿粉对路面混凝土性能的影响，并针对生产中出现的问题，提出了改进措施。结果表明，适宜的矿粉掺量以及适宜的砂率有助于提高路面混凝土的抗折强度和耐磨性。%Taken the actual proj ect as an example,the effects of slag on road concrete were studied.The improve-ment measures were put forward in connection with the problems in production.The results showed that the bending strength and abrasion strength of road concrete could be improved by adding suitable amount slag and setting appropri-ate sand rate.
