Effect of Pre-Wetting Super-Light Aggregate Reinforced Aerated Concrete

Abstract:

In this study, the effect of pre-wetting super-light aggregate on the microstructure of the aerated concrete was discussed. The experimental results show that: using Scanning electron microscopy to magnify the interface between mortar and aggregate in aerated concrete to 200 times their normal size, the pro-wet treatment densifies the interface,and to 20000 times,fibrous CSH gel and lamellar tobermorite interweave each other and form very pre-pressing structure on the surfaces .
