前景:目前我国市政用料基本上有四大类别:一是天然石材,用天然石材铺设广场或街道,豪华美观,档次高,但随着我国禁止山石开采范围的扩大,石材资源越来越紧张,水电运输成本不断大幅上升,使天然石板的成本越来越高。对于全国绝大多数的城市,采伐天然石用于市政的消费是不现实的;二是彩色水泥砖,前几年这种砖几乎占去了全国市政铺路用料的80％,风光无限。由于彩色水泥砖技术含量低,办厂门槛低,同一地区办厂者很多,形成恶性竞争。偷工减料
Prospects: At present, there are basically four categories of municipal materials used in China: First, natural stone, paved with squares or streets with natural stone, luxurious and beautiful, high grade, but as China bans the expansion of the scope of rock mining, the stone resources become more and more tense As the cost of hydropower transportation continues to increase substantially, the cost of natural stone slabs is getting higher and higher. For most cities in the country, it is unrealistic to cut natural stone for municipal consumption. The second is colored cement bricks. In the past few years, this brick accounted for almost 80% of the national road paving materials. Due to the low technical content of the colored cement bricks, the low threshold of the factory and many factories in the same area, vicious competition has been formed. Cut corners
