西安～铜川一级公路通过三原县罗李小学路段，由于公路距学校很近，交通噪声对学校的环境造成不良影响，故修建了近300m长的声屏障工程。在该工程设计和施工中，进行了一系列测试研究，采用炉渣无砂大孔混凝土块作为墙体的主要材料，取得良好的隔声效果，经济效益也十分显著。
The Xi’an-Tongchuan Class I Highway passes the section of Luo Li Primary School in Sanyuan County. Since the road is very close to the school, traffic noise has an adverse impact on the school environment, an acoustic barrier project of nearly 300m long has been constructed. In the project design and construction, conducted a series of test studies, the use of slag-free macroporous concrete block as the main material of the wall, get a good sound insulation effect, the economic benefits are also very significant.
