1. Cement is a powder that works like a glue, activated by water. Different cement recipes will yield different properties in the cement. 2. The more water you use, the easier the cement will flow, but the weaker the final structure will be and the longer it will take to set. For quality purposes, aim for a low water to cement ratio.
