摘要
本文针对南平闽江大桥水下不分散混凝土力学性能进行了试验研究,对配合比进行了设计调整,检测TW-NA外加剂对水下浇注混凝土的抗分散性、流动性、自密实度及力学性能的影响,研究应用结果表明,TW-NA水下不分散混凝土外加剂的作用效果明显,制备的水下不分散混凝土的各项指标稳定。
Experimental study on the mechanical performance of non-dispersible concrete in water of Nanping MingJiang River Bridge is carried out, and mix on a design adjustment. Tested TW-NA effect on antidispersive, fluidityself-compact and mechanical property. The result shows the admixture of TW-NA has favorable properties in underwater non-dispersive concrete.
