清水自密实混凝土在隧道二衬中的应用研究
|
摘要
文中将兼具自密实性能与表面清水效果的清水自密实混凝土应用于隧道的二次衬砌,通过对成型后的二衬结构进行外观质量检验,研究其力学性能并对经济效益进行分析。结果表明,清水自密实混凝土的清水效果理想,表面清水镜面效果十分明显;使用的清水自密实混凝土强度达到C30;综合各项成本后,C30清水自密实混凝土成本明显低于普通混凝土。
The fair-faced self-compacting concrete which has both the self-compacting property and clean appearance was applied in the second lining structure. After the structure was formed, its appearance and compression strength was checked, and its economic effect was analyzed. Results show that the surface of fair-faced self-compacting concrete is optimum and the mirror effect is obvious. The fair-faced self-compacting concrete we used is up to C30. After synthesizing material cost, labor cost and decoration cost, it is found that the cost of C30 fair-faced self-compacting concrete is obviously lower than common concrete.
