nature : light concrete is one of the main varieties. By the light of coarse aggregate, light fine aggregate (sand or ordinary), cement and water used to prepare dry bulk density of not more than 1950 kg / m 3. By use can be divided into different insulating concrete, structural and insulating concrete structure lightweight aggregate concrete three categories. According to the compressive value can be divided into CL5.0, CL7.5, CL10, CL15, CL20, CL25, CL30, CL35, CL40, CL45, CL50 11 intensity levels. In addition to widely used industrial and civil engineering for the load-bearing structure and envelope, but also for the construction of bridges, poles, ships, and high-temperature furnace chimney and the refractory lining.
