Given that, most of the MSW incineration (MSWI) bottom ash (BA) are disposed in...

The influence of hydration on the microstructure development of cement paste with bleeding: An NMR study

Bleeding can be described as water coming out from fresh cement paste, which not only affects the homogeneity at fresh stage but also decides the hardened state structure. Previous studies have focused on the determination or simulation of the bleeding extent of fresh cement paste and give objective conclusions. However, there are rare...
