Cement undergoes a chemical reaction when it is reacted with the atmospheric moisture this process is termed as hydration. Moisture is very harmful to cement. Cement becomes useless once it is hydrated with water. The presence of excessive moisture is the reason for finding a lot of lumps in old cement is due to content in it.

Dry Concrete range are Bico + Cover, Fence dan Colomn, Topi Uskup, Kanstein, Square Paving Stone, Color Paving Stone. D ry cast has a low water to cement ratio and a zero slump. This "Dry Process" allows you to use one form and pour numerous pieces without deformation. The concrete is stripped and resembles Hard clay and dries within and hour.
