Does water weaken concrete?
The rule of thumb: One gallon of water will increase the slump of 1 yard of concrete by approximately 1 inch. This should only be taken as a rule of thumb as there are various other conditions, like temperature and air content, that will change the water required to increase concrete slump.
Does plastic stick to cement?
Cement sticks very well to plastic, or at least Portland cement concrete does. … There are plastics that have an oily film or a very slick surface that cement wouldn’t stick to, or at least not very well.
