In this work, we propose the synthesis of ZnO nanostructures through the thermal oxidation of ball-milled powders with the introduction of Mg and Sn doping species at the preliminary step of milling. We investigate the advantages and challenges of this two steps process for the production and fabrication of highly crystalline ZnO nanowires. This simple method allows us to fabricate ZnO ...

graph of compressive strength and water cement ratio

How to Calculate the Water to Cement Ratio. The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds) So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a 50 water to cement ratio.
