May refer to “cementing the deal” making an agreement solid and bonding.
If you are mixing cement then it would refer to something you are currently planning on building such as a career, a relationship, etc.
If the cement is wet then it refers to something new and fresh. Are you “laying the foundation” for something in your future?
Cracked or crumbling cement indicates something in your life that you thought was solid, such as a relationship, an opportunity, your job, etc. is starting to crack and fall apart. It is a warning that you need to find a way to repair and strengthen the situation before it crumbles completly. Also look at your own state of mind, are you starting to crack under the pressure?
