摘要: An orthogonal experiment was developed to study the effects of mix proportions on properties foamed concrete. Then, based demands concrete used as a seismic isolation material for tunnels in rock, optimum were obtained, and new type developed. Test results showed that had low dry density, water absorption rate, certain strength good ductility. In addition, simulation coating rock could significantly decrease stress plastic zone tunnel lining. view its cost concrete, it is suitable feasible use rock.
