One of the important materials in creating concrete walls, houses, roads and more is cement, a substance that sets and hardens independently and can bind the materials together. As we are building  a concrete house we need cements in every part of the house,  the work cannot be done continuously  so when we have extra funds we buy materials like cement bit by bit.

We have to keep the cement in a safe place to avoid moisture, that can begin drying and hardening. Once the cement went on this process it won’t be as effective binder or worse it is going to be useless that’s why if you have noticed a sack of cement is lined up  with a plastic sheet to keep the moisture out.
