Cement is the most important construction material which is widely used in modern construction. Cement is generally used to prepare concrete and mortar which are used to make RCC framed structures. Cement has binding properties and can easily mix with aggregates and forms a homogeneous mixture, which hardens to give a stone-like strength. The strength and durability of the structure are mainly dependent on strength of cement.
There are many manufacturers of cement worldwide. Many times they adopt bad practices to manufacture and pack cement to increase their profits. The cost of cement is more than other construction materials (coarse aggregates, fine aggregates etc.) and it also affects your overall project cost. Hence we must be aware before buying cement bags because sometimes cement bags arriving on the site may be a duplicate. Duplicate or adulterated cement will decrease the life of the structure. You have to check some basic standard specifications before you buy it. You must check the information that is printed on a standard cement bag.
