纳米混凝土物理力学性能研究初探

Primary investigation of physics and mechanics properties of nano-concrete

本文通过对比试验,对掺有0 5%纳米SiO2的粉煤灰混凝土的物理力学性能进行初步研究,试验表明掺0 5%纳米SiO2可提高粉煤灰混凝土7天和28天的抗压强度与抗折强度;结合微观电镜扫描试验,本文深入分析了纳米SiO2可提高粉煤灰混凝土密实性和强度的机理。。

Based on the comparison test on the compressive and tensile strength and submicrostructure (by scanning electron microscope) of concrete,some conclusions are drawn that nanoconcrete have higher strength and more compaction and better durability.
