What will happen if cement is not used in making concrete?

Concrete is a mixture of cement, water, sand, and gravel. Cement helps to make structures strong and leakproof. If cement is not mixed into the concrete, the structures made using it will not be strong and leakproof, thus increasing the chances of collapse.
