Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your
issue. First I’ll need some more info so I have a more complete picture of you situation.
Is this on a tub or a stand up shower?
Ok, since I doubt you put concrete down the drain I have to assume the material you describe is calcium deposits and soap residue. I'd stuf a rag in the drain and cover the blockage with a product like CLR. Even white vinegar can work to dissolve this type of deposit
You may have to chip some of it away. You can suck out any solids that fall down the drain with a wet vac. They will stop at the trap.
