通过室内试验,文章初选并比较了两种改性混凝土的路用性能。研究发现,当按照合理的比例三掺适量的高效减水剂、硅粉和矿渣后,普通道路水泥混凝土的力学性能和耐久性能均较有大幅度改善。
Through laboratory tests, the paper preliminarily selected and compared the road performance of two types of modified concrete. The results show that the mechanical properties and durability of ordinary road cement concrete are greatly improved when the appropriate amount of superplasticizer, silica fume and slag are added in a reasonable proportion.
