Why is my cement crumbling?
Water. If too much water is introduced to the mixture, the cement and sand cannot bond with each other and will instead fall apart. As the concrete starts to dry, this results in a crumbling area where the particles aren’t sticking together.
What causes cement to crumble?
Concrete seems like a stable and permanent material, but it remains porous and will absorb water. When this water trapped inside the concrete freezes, it pushes the cement binder apart. This expansion, and the resulting contraction when the water melts again, causes crumbling.
