Yes, cement can indeed be used without sand. Cement and water can be used as a slurry. Now, we do use white cement + water at time for certain applications like filling joints or applying it on wall cracks or for minor plastering works at times.

Now, white cement is nothing but a regular grey cement without ferrous oxide and manganese oxide which impart grey cement its colour. It is indeed cheaper to make grey cement and hence it is more prevalent and more widely used, except in specialised application, where grey colour is undesirable.cement flower pots suppliers

Let’s understand this in a slightly better context. Cement is a binding material and it develops strength once it reacts with water. The strength in case of cement mortar (which is a mixture of Cement and Sand with water) is due to sand present in it. However it does not mean that more sand results in more strength, proportion of sand to cement is decided based on the desired strength. Cement coats the sand particles and provides binding and subsequently the strength is developed based on mixing proportion.

Similarly, concrete derives its strength from coarse aggregates (metal/ jelly), fine aggregates (natural river sand/ crush sand). The voids creates by coarse aggregates are filled by sand, and voids creates by sand is filled by cement particles; and all put together along with water makes up an impervious mass post setting (hardening).

Hope I was able to answer the question with required details.
