In this paper, different types and particle sizes of nanoclay (nano-metakaolin?NMK?and nano-attapulgite?NMA?clay) were selected to study the effect of nanoclay on the properties of cement-based cementitious materials. The stability of different nanoclay ...

series of SEM micro-graphs were obtained from the cracked surfaces of samples from two types of AISI-1018 steel after applying fatigue tests at a stress ratio ofR=-1. Various strain-control levels were used in the range ±0.0008 = ? = ±0.0014 following a ...
