Abstract: In this paper, we synthesized LiMnO2 compounds doped with different amount of Ni by coprecipitation. The composition of the sample can be determined by ICP tests and energy loss spectroscopy. We found that the grain size decrease with more Ni doped .We found that the space group of the material is R-3m through XRD and Raman spectroscopy and with more Ni doped there is a blue shift in Raman spectroscopy. We can say that with more Ni doped, the material contains more Mn4 + through XPS analysis. But when Ni is doped excessively, there will be Ni3 + in the material. SEM analysis showed that corrosive effect of LiOH may have fatal effects on the electrochemical properties of the material.

Abstract: To improve the anticorrosivity of concrete, an analysis was made to the corrosivity/anticorrosivity mechanism of concrete followed by some relevant technical measures proposed to take. In the experiments, anticorrosive agent was used to prepare the high-anticorrosivity concrete with different proportioning. Both the experimental and application results showed that the concrete we developed had high physical/mechanical properties and durability especially the high anticorrosivity feature.
