我国轻骨料资源十分丰富,据不完全统计,目前生产陶粒的厂家有30多个,设计生产能力在140万m~3以上。不仅能生产容重等级600～800kg/m~3级的普通陶粒,而且可生产400kg/m~3及以下级别的超轻陶粒。为节省能源已研制出非煅烧陶粒,目前先用在砌块中,其成本较煅烧陶粒降低20元/m~3左右。煤矸石的资源也相当丰富, China’s light aggregate resources are very abundant. According to incomplete statistics, currently there are more than 30 manufacturers that produce ceramic pellets, and the designed production capacity is more than 1.4 million cubic meters. It can not only produce common ceramsites with a capacity rating of 600-800kg/m3, but also can produce ultra-light ceramic granules of 400kg/m3 and below. In order to save energy, non-calcined ceramsite has been developed. It is currently used in blocks first, and its cost is lower by about 20 yuan/m~3 than calcined ceramsite. Coal gangue resources are also quite abundant.
